    Lightroom 5.4 to Lightroom Mobile sync is soooo slow - why no local sync?

    x2mt Level 1

      I am testing the new Lightroom 5.4 with Lightoom Mobile. What really annoys me is the fact that all photos are going up to the Creative Cloud. I have private pictures which should be private. Always. No upload. No Cloud sync. It is important!

       

      Speed is the next major problem. LR 5 is way too slow for a fluid workflow. But this is mentioned from other users.

      What absolutely makes me sad ist the sync speed of LR5.4 to LR Mobile. 100 Photos took up to 4 hours. On a typical wedding I have 2000+ images. Depending on the speed of the first 100 photos I have to wait 80+ hours? Are you kiddding me? This makes LR Mobile unusable. My clients are expecting results fast. Speed is one factor to the next contract.

       

      Overall, I don't want to sync anything into the Cloud. I want a to use my fast local sync via WiFi or USB. Only those two options. I want to sync photos even without any internet connection successfully and quickly.

       

      I'm fine with authentication with Adobe servers for licensing verification. But that's it. The rest should be configurable by the users whether they Cloud sync or not.

          @x2mt: I totally agree with your point. I started testing the Adobe Lightroom Mobile and Adobe Lightroom 5.4. It took for ever to sync 2 raw images(smart previews). I also second that I want to upload my images to the cloud. Adobe can charge me for the app if needed, Adobe can verify my license but I dont expect them to force me to upload my private pictures on to their cloud. Moreover forcing me to purchase the annual plan of Photoshop cc plus lightroom(the cheapest) when I already have bought a full license of Lightroom 5 (I dont use Photoshop cc) is a no go. I hope Adobe changes the policy soon.

            I was so hopeful for Lightroom mobile.  So far, though, I'm not very enthused with this product.  What I was hoping was to be able to view all the photos in my catalog on my iPad.  I use LR as a casual photographer, not as a professional.  I have ~50K photos in the catalog.

             

            The first thing that struck me was that I had to have photos in a collection.  That's a bit of a pain - I don't tend to use collections too much.  I do use a lot of smart collections, but even those are supported for syncing it seems.

             

            Secondly - the price.  It is pretty expensive for what it is.  I'm looking at it from the perspective that I own LR, and I just want LR on my iPad.  I guess I can adjust my thinking a bit since I think the price includes the price of future LR upgrades?

             

            Lastly - yes it is so slow.  I took an old collection and synced it.  It had 2000 photos from one of my vacations, and it was very very slow to get them on the iPad.

             

            So for me, I don't think I'll be signing up past the trial.  The price, only working with collections, and the speed are pretty big issues for me.

              Right, the idea you'd sync these huge raw files, just to view them on a non color managed device, to sit at the pool 'editing', then have to sycn back to the desktop, makes this a solution in search of a problem. So if I understand the 'workflow':

               

              Take camera card to desktop or laptop.

              Copy images there then wait to sync to iPad.

              Do less work at a slower pace and without proper preview color on a device that's not really designed for this task.

              Sync back to desktop or laptop. To edit by the pool? I'll just take the laptop.

               

              What am I missing here? Even if the sync was super fast?

                Yep - clearly not a solution for you.  For me - one of the things that I would use it for it to weed out rejects.  I wouldn't mind being able to do this on my ipad while I'm not at my main PC.  I'd also like to be able to do some light retouching, as well as use my ipad to find photos in my catalog to share via email/facebook etc.

                  That's my primary purpose, too.

                  But the slow sync method will work against that and makes it impractical for daily usage. Hopefully Adobe rethinks the transfer workflow.

                    Short of accessing a faster internet connection there is no way of improving the sync speed. Not now or any time soon. Had there been, we would have it now. The other issues mentioned above can be worked round by those willing to compromise their existing workflow. Some will do so at any price, others will wait until Lr mobile fits with our workflow rather than dictates it.

                      My hoped-for workflow:

                       

                      I'd like to travel without having to take a laptop; just bring the iPad. I'd load images onto the iPad using the camera connection cable. I could pick, add keywords and rate them in LR mobile. Maybe I'd crop and adjust a bit to show the pix to folks on the trip. When I got back I could import and sync from the iPad, capturing the added metadata and simple adjustments.

                       

                      The Photosmith app does part of this, but not all, and not as smoothly as LR mobile. If only LR mobile sync were fast....

                        Thanks for everyone's feedback.  When reporting sync speed would you mind testing your internet connection speed and reporting that with your results so we can isolate the potential bottleneck?  I recommend speedtest.net for a simple Up/Down performance test.(Don't run that test while syncing with Lr Mobile) 

                         

                        Also, I realize that some of you are uncomfortable with your images going through Adobe's cloud before reaching your iPad.  But Adobe's servers need to act as an omniscient entity to reconcile your efforts between multiple clients.   We already have a web interface and the phone app is on the way.  A centralized, sever-based agent is needed to keep clients from colliding with sync conflicts.  Adobe will need to gain your trust in our ability to keep your images private and secure and we've actually provided online photo management solutions for many years without incident. (Photoshop.com then Revel)

                         

                        Let's keep the feedback coming.

                         

                        Regards,

                          Ian,

                           

                          I think the direct to PC option is a method to go around the internet sync.  For example - the iPad has multiple ways to share content.  You can airdrop (bluetooth), you can do a wifi sync to iTunes and you can sync via iCloud.  Translate that to LR, and they have implemented the equivalent of the iCloud.  I'd love to see the product  evolve to support alternatives to the cloud.

                            Exactly! And that isn't going to happen any time soon. And to answer Tom's question, my internet speed is quite good*. That's not a fix for moving huge amounts of data to a device that is ill suited for the job when another tool (my laptop) does the job better and faster. And is color managed. And provides every tool in LR and other tools provide that I need. So in the end, I can do more faster and better just sticking to my laptop and an external drive with all my photo's than anything I could do with LrM and an iPad. The iPad is a nice tool for some tasks, like how it sits in my kitchen with all my recipes. Or surfing the web. For large (and raw) image editing it's a sick joke. And I'm a patience fellow. I recall waiting 20 minutes to rotate a 15mb Photoshop document 1 degree on a IIci with 8 megs of ram back in 1990. I'm willing to wait but the tool has to be adequate for the job (the IIci was back then). Today the iPad isn't nor is getting all that data from point A to point B then back to point A again.

                              Your preaching to the choir regarding direct connection but as Tom has already indicated there are reasons for the Cloud based approach. Some of those are technical others may well be commercial, I don't know.

                                My internet connection is decent/typical.  As tested with Speedtest.net, I get 25Mbit down and 1Mbit up (cable).  I have a collection with 2000 photos synced from my PC.  On my iPad Air, I have the LR app open and it is sitting there open.  It has pulled down 171 photos so far, and it adds another one at the rate of about 1 every 10 seconds or so.

                                 

                                I think the issue is on the LR destop side.  It says it is "Syncing 1,963" photos. By looking at my router's realtime reporting, I can see that I'm maxing out my 1Mbit upload. The photos in my collection are pretty large - RAWs between 10 and 21 megapixel each.

                                    The files synced to the iPad are actually Smart Previews (i.e. lossy DNG), not your actual raw files. They weigh in at around 2.5MB each, irrrespective of what size they were to begin with.

                                      Something is wrong. With the bandwidth you have available the files should have synced closer to 5 minutes rather than forty. My connection, at best, is 350kbs upload and I can sync 200 in around 1 hour 50 minutes.

                                        Raw files are synced from the iPad to the computer if they originate on the iPad, for example those imported to the iPad from a camera or memory card.

                                          Not sure where you get that idea from because Lr mobile does not support raw files from any source.

                                            Yeah, I spoke too soon. You can import from the camera roll into LR Mobile. I had translated that in my head to importing from the photo library on the iPad, which can contain raw files. Raw files imported onto the iPad don't go into the camera roll. Many other apps can handle them, but not LR Mobile. My hoped-for workflow won't work; I was asking for something that's apparently not the purpose of LR Mobile, at least for now.

                                              I just created a collection of 91 photo's RAW files.

                                              I selected the options to create virtual copies and sync with mobile.

                                              It took 3 mins to create the collection and copies and a further 51mins to sync.

                                              I have a fibre internet connection with 68mb download and 19mb upload speeds.

                                               

                                              I then opened up the Lightroom app on my I-Pad and the sync took about 4 seconds.

                                               

                                              The collection had previously been exported to full size JPGS totaling 765mb. I then uploaded them to a test gallery on my website and the upload time was 12mins.

                                               

                                              Is the sync speed issue within the Lightroom desktop application?

                                                I've no idea where the problem lies, but be very aware that the download to your iPad requires that you either loupe through the individual images or set Lr mobile for Offline Editing (click on 3 dots in right corner of collection image). If you remain connected to internet these steps aren't necessary. However, say you're in a hurry and go offline as soon as the collection appears on iPad then there's a good chance you'll find that there are no images to work on. Bottom line here, Lr mobile needs to have access to the smart previews in Cloud or downloaded to your iPad. I would be very surprised if it took only 4 seconds to download 91 photos.

                                                 

                                                Note, I expect a lot of folk will be caught by this, and Adobe have said next to nothing as a warnning.

                                                  Lightroom is absolutely fabulous and the mobile tool had promise, but with no direct sync from PC to the iPad, it makes it a toy for iPhone pics at best. As a number of guys had mentioned above, the best use of a companion tool like this is the ability to sort, pick and keyword your images for further development on the PC/MAC, but the speed at which the cloud sync happens makes it completely impractical anyone else in the world other than those in Silicon Valley I presume and even then, it seems to take its time.

                                                   

                                                  For those of you looking for a tool that is a real work companion, try PhotoPhile which has all the "Selection" capabilities with bi-directional sync but has no editing, which is fine!

                                                   

                                                  Adobe, we understand the vision and the drive to get everyone into your cloud, but please think of the practicality for a serious user.

                                                    My local Internet is 150 mbit/s down and 40 mbit/s up. And it took forever to get some images to LR Mobile. In comparison it took just seconds to get some images into Photo Manager Pro which my favorite app to show photos to my clients. Via WiFi of course. Independent of any cloud or internet connection. Everytime, everywhere, very reliable.

                                                    I am very often in hotels with very slow or non exisiting internet. In those locations it is an important goal to catch the clients enthusiasm.

                                                     

                                                    And as mentioned in my opening posting: Privacy is a very, very important part. If Adobe has no further ideas to develop an reliable sync option without transfering all images to the cloud or over need of internet: This Creative Cloud stuff is no option for me. I am very sceptical in software abonnemments and Creative Cloud "features". I see more benefit on Adobes side to get a fixed income and bounded customers.

                                                     

                                                    i am sorry to say that: I am out if there is no fundemantal rethinking in privacy, sync method and sync speed.

                                                    And beside of that: I need a workflow which works fast, reliable and completely offline as well.

                                                      The upload speed does not seem to be the issue.

                                                      It seems that the Lightroom desktop application takes an age to do the syncing just as it takes an age to export images.

                                                        I agree, this is quite disappointing so far, and I'm having trouble imagining what type of workflows in which this will actually be useful.

                                                         

                                                        I'm on standard cable internet 15Mbps down 1 up. I made a new catalog just for testing with 10 frames from a 5D Mark III, 22mp raw. The total smart preview file size is 18.1MB. It took 6min 30sec to upload this test collection and about 1 more minute to complete the sync on the iPad Air. Estimating this out to about 45sec per image, syncing collections of hundreds or thousands of images is not going to be practical.

                                                         

                                                        Granted, part of this bottle neck the internet connection, but part of it is something in lightroom's upload performance. Uploading an equivalent sized folder (18MB) of jpegs to dropbox took only 3min 39 sec.

                                                         

                                                        Is their theory that we would make smart previews for all our thousands of existing photos, have them available in various collections and then sync those collections overnight so we can work on them at some future point?

                                                         

                                                        I'm happy to hear about the other programs mentioned in this thread. I too am looking for a way that I can access all my 150k photos from any device, anytime, anywhere. But I'm afraid until we've all got super fast upload speeds at home, and unlimited data caps on wireless devices this is not going to happen for several more years.  I applaud Adobe for trying to provide a solution with the smart preview technology to compress a 30MB Raw down to 2.5MB DNG, but this is still not practical with today's home broadband.

                                                          AAh, I see why it's so slow, all the images are going up to the Adobe server before coming to the Ipad. With 19MB ownload and 0.5 mb upload, this is not a workable option for me.

                                                           

                                                          What about a quicker option for those of us who have just one Desktop computer and one Ipad that gives us the option of bypassing the cloud?.

                                                            Somewhat disappointed in the speed of transfer and then, when on the iPad, the slowness in display and access to tools when scrolling from one photo to the next.

                                                             

                                                            It is far simpler to continue to use my MacBook Air 'on the move' and have access to all the bells and whistles without having to find things to do waiting for LR Mobile to catch-up!!

                                                             

                                                            I therefore remain unconvinced that LR holds any real advantage over using PhotMechanic, Bridge and Photoshop where speed of workflow is far better without the constraining effect of a catalog system.

                                                              @Tom: Regarding the sync, I have noticed that once I add a bunch of photos for upload to a collection, it does not show up as and when each individual photo in the collection is synced (Btw I have already created smart preview before starting the sync, when I import the pictures to my PC from my camera). I need to wait until all the photos are synced and only then is my collection updated on iPad. Any cloud based service like Dropbox or onedrive the files are uploaded and synced individually. This coupled with the high upload time it makes for a painstakingly long workflow. Considering I have not missed anything I also do not see the status of my sync. What percent of my collection has been synced and how much is pending which would help me estimate time for the whole process. At the moment it's kind of a black magic that's happening and a slow one at that.

                                                               

                                                              Your point regarding sync conflicts, it would be very useful if you could provide us the option other than sync over cloud like over private wifi and USB etc.. (We trust the creative minds in Adobe to come up with a solution for this :-)) Let Your users choose what best suits them. Power of choice is a wonderful thing and highly appreciated by creative minds. More over passing all the creative content through your servers gives rise to security protection. Anyone who wants to access them knows where to attack. You might have the best intention to protect your customers privacy and content but there are always people out there trying to prove you wrong. Adobe servers where attacked last year and there is no guarantee this will not happen again. So please do give us an option, to either place our trust in you or not. But not force us to do so. Like you have won our trust in your products give time till we do so in your new product(cloud) until then let us enjoy your products that has won us over to its maximum capabilities.

                                                                    Tom, thank you for taking your time to come here and enlighten us with the decision making process behind what was done. Like it was said before here, the Lightroom Mobile so far has been very, very frustrating. I came home very excited to test it and make my dream come true. To be able to take my catalog (or a shoot) with me on the subway, etc and be able to choose the photos on my iPad. See, I am a photographer and I shoot mainly fashion and beauty, so my workflow starts as soon as I finish shooting by importing all images into Lightroom and then going through the painstaking process of choosing which picture to use. I would shoot anywhere between 5-12 looks in a day, around 100 photos per look and at the end of the process I need to choose only one photo from each look. This normally involves going back multiple times to be able to get to only one from each look. The LR Mobile would have been the perfect solution for me, making me able to look at photos while out of the office, on the subway, at home, etc. It would have made my editing process much faster (or less slow). Instead, I've been sitting and waiting for 6 hours so far and only 18 photos showed up on my iPad (from the 500+ that were chosen to be synced from my desktop LR. Now I know it's not my internet that is making it that slow because I have 80+Mbps of download and 40+Mbps upload. And that haven't helped me much as my LR is stuck on "Syncing 527 photos" for the last 5 hours. Most professional photographers that I know deal with a huge amount of photos from a photoshoot. Wedding, fashion, advertising, we all shoot 1000+ images in any given work day. To come home and have to wait 100 hours before we are able to edit on the iPad is just not useful. This will be useful for the amateur photographer that will take photos of their children/dog/flowers and want to be able to show their guests the photos without having to get them in front of the computer.

                                                                     

                                                                    Now I understand what you said about having to have a centralized place so that all the clients up to date on the changes, and I think that is great but I also think that it's paramount that there's a different way of syncing, a faster, more efficient way. Even if it is, like mentioned, not a "everything in sync" solution. Something like sync the desktop to the iPad and only those two work together. If both are changed before the next sync, a "the 'blabla' catalog has been changed since you last synced, do you want to overwrite it?" takes care of the problem, much in the same way that Photoshop asks us when we are saving something that has been somewhat modified by some external agent between saves. But the beauty of shooting all day, loading everything in Lightroom at night at the hotel and in the morning catch your flight and edit your shoot on the iPad while traveling, or being able to show the clients on the iPad right after you shot the wedding, or (what I was dreaming was going to be possible just to have my dreams crushed when started to use it) shooting tethered on the job and giving the art director the iPad so that he/she can see the shots without having to stay in front of the computer during the whole shoot. Now THAT would be a game changer! That was what I was expecting from LR Mobile but unfortunately got disappointed. I'd pay for the app alone if it did that!

                                                                      I am not uncomfortable myself, but I can understand if someone are. To have fool-proof sync, we definitely need a centralized server-based agent to keep things in control, but in theory, this central server does not need the photos - just the metadata. This is most likely far from the current sync design, but it should theoretically be possible to allow for local sync of photos while metadata are synced via your servers. This will allow for both much faster sync (wifi or even cable) and retaining an option for photographers that are in desperate need for privacy to have full control of where their photos are. On the other hand - how safe are photos that are stored in cache (or offline) on a mobile device anyway? But faster sync at least seems to be a big issue for someone.

                                                                      • 33. Re: Lightroom 5.4 to Lightroom Mobile sync is soooo slow - why no local sync?

I don't believe that most people have these made during import so they need to be created before uploading. This is a huge bottleneck and can only be resolved by turning on the generation of smart previews during import. Or by buying yourself a ridiculously fast machine . But I also feel that there is a lot of room for performance improvement when it comes down to generating smart and normal previews in LR. The same goes for exporting. I know that the LR team doesn't really want to use the graphics card but maybe it's time to start thinking about it. I could offer huge performance gains.

                                                                         

                                                                        2. The upload speed. The speed at which LR uploads is not really an issue (it seems to max out my upload speed, but I need to measure it to be 100% sure). The issue is that, even though smart previews are small, they are still too large for most home broadband connections to upload effectively. A lot of people have really fast download speeds but ISPs limit upload speeds. And this is an issue that won't be resolved quickly, and has nothing to do with LR or Creative Cloud.

                                                                         

                                                                        Solution: As most of us probably have our computer and iPad on the same wifi network it would be nice if there was an option to use wifi sync. I understand that creative cloud servers are being used to resolve sync issues. So why not have the option to upload a small file to the creative cloud that contains all the metadata about the current running sync and move the smart previews over local wifi or LAN. And optionally you could, after that sync is complete also start to upload the smart previews to CC (or simultaneously) from either the iPad or the desktop LR application (or both simultaneously).

                                                                         

                                                                        Unfortunately I also realise that local sync has it's own issues. You would have to copy all your smart previews to your iPad instead of just downloading them "on demand" just like it is now. Which can be an issue on devices like the iPad, where space is limited.

                                                                        That's why I suggest doing a double upload. First a quick upload, over wifi, to your mobile device. And then a slower upload to the cloud. That way, when LR mobile sees that some collection is also available on CC it would give you to option to delete the local files on your iPad. But until all the smart previews are on CC, LRM won't give you the option to delete the local smart previews, because they would be effectively gone with no way to access them again.

                                                                        I, again unfortunately, realise that this solution could be confusing to some people. So I don't know if it's a good idea to implement such a thing.

                                                                            But what is your upload speed? My VDSL line at home offers 4mbit upload which means a theorical throughput of 512KB per second (4096 kilobit / 8). Substract the overhead and you get a realistic max upload somewhere around 420-450KB/s. That's kiloBYTE not kilobit.

                                                                            Every smart preview DNG is on average 1MB (for me). So in theory it would take around 2,5 seconds to upload. Add some metadata, some time to fetch the next file and so on and that's where you get to a real life upload speed of around 4-5 seconds per smart preview on a 4mbit UP line.

                                                                            I do believe that there is some room for improvement. LR doesn't constantly max out my line, it goes somewhat up and down right now. A possible solution would be to pack a few smart previews in one file and upload it. The fluctuation in speed I'm seeing right now is, probably, caused by LR sending every DNG individually. So maybe it could shave off 1 or 1,5 seconds. But that's just in theory..

                                                                             

                                                                            How long does it take for you, in seconds, to go from "400 remaining" to "399 remaining"? On my machine it's 4-5 seconds per image. Which is very slow but ultimately caused by the slow upload speed provided by my internet connection.


                                                                            To make this really fast and usefull we need 20mbit or more upload speeds. Unfortunately those lines are rare.

                                                                                We really need wifi sync and as an added bonus this would also lower the load on CC servers, which could also be an issue right now. Too many people trying out their new LR Mobile at the same time.

                                                                                The majority of home broadband infrastructure is not really ready for the cloud because of slow upload speeds.

                                                                                I once tried an online backup service. I would have taken 2,5 months 24/7 uploading to back all my stuff up. Online backup only sounds great on paper.

Both are excellent and fast! I do hope that the speed issue is a result of the number of users getting online and may calm in time!

I want to be able to load raw files from my camera to my iPad, sort and do basic adjustments in the field, and then sync to my desktop when I get home, not vice versa. If the only way to get photos into Lightroom mobile is via the desktop version, what’s the point? I’m already home.
