I am new to Lightroom and work with a laptop at home and a PC at work. Before I started to use LR3 I simply duplicated my pic files onto both machines, edited on whichever machine I wanted and then synchronised the folders. This system provided me with a working copy at either home or work and also a backup copy on the other machine.
I would like to operate the same system with LR3 but am unable to figure it out due to the automatic filing system used by the programmme to seperate the raw files and the instructions for those files.
Can anyone provide me with simple step by step instructions on how to transfer the files/instructions by using a flash drive and "Copy and replace"system
as I am totally confused by the grammar, syntax, and terminology used by Adobe.
I too work on two machines: one at work and one at home. I use the export/import catalog functionality that takes care of everything.
My workflow is:
Note: If you know you worked on old files, that already exist on the other computer, do not check the "Include negatives" option during export. This will save a lot of disk space (on the flash drive) and time.
Thanks. I've already tried that method but the flash drive has come up with 3 seperate folders. When going to import it asks me to select the photos.
Which file should I then choose ? Also, what other options should I tick ?
With your system are your photos all in one folder or spread out in different folders?
In my opinion (notice, MY opinion), the easiest way to do this is to have the catalog, the images, previews, (in other words, everything) on an external hard drive. It's easy, it works well. Then, when you are finished with the editing, you could export a set of JPEG images for viewing to each computer. But the master files remain on the external drive. It's a way to do it, but you might not like that idea. I do.
If you're following Dorin's instructions, be sure you choose File->Import from Catalog, don't just click Import. Then you'll find & choose the .LRCAT file from your flash drive (not photos or folders). The catalog file knows where the photos are (so you don't have to).
My flash drive shows 1 photo file, previews Irdata file, and 1 lrcat file. Do I ignore the photo and preview files and if I can I avaoid loading them can you tell me how ? Does the "dont include negatives" method cover it ?
if you see only 1 photo you did export only 1 photo in the catalog.
Make sure you select all (e.g. <ctrl> A or remove the tick from "export selected photos only" in the dialog box of export-as-catalog =>will pick the total folder).
What Dorin mentions are catalogs as transportation vehicles between the two LR computer catalogs.
Let's assume you start on your home-comp and transfer to the work-comp.
When you EXPORT you give a name "home-to-work" for the transport catalog. You decide if you include the pictures by ticking "exclude negative files".
You would do so only for the first time, when your work-comp would not yet have them.
These are the original files which would never be touched, but which LR needs to have available to do develop work (i.e. to write develop instructions into its database). [Or maybe only you need them in order to have LR display the effects of what you are doing, if your slider settings achieve your desired result.]
When you transfer your new settings from the work-comp to the home-comp which has the original files already you only need to transfer the DB-records for the files, i.e. the catalog parts. Then it is sufficient to export-as-catalog (name it "work-to-home") without the tick for the negative files. Which will obviously save a lot of data to transfer.
As would leaving off the tick for "include available previews", but then your receiving computer would have to render the previews itself - your choice where you spend the effort.
Depending on your ticks checked in export dialog the data on the transfer stick will show different folders:
On the receiving computer, when you IMPORT FROM CATALOG, you only select the *.lrcat-file.
In the dialog box you decide if you import the negative files (prereq you had included them) or if you just add them without moving (why not leave them on the stick i.o. actually copying over to the work-comp?). If there are no new photos, but just new settings, you can either overwrite your old settings (which is probably your intention) or tick "preserve old settings as virtual copies".
When you use Dorins smart collection "Touched today" the virtual copies should not show up upon re-export on the way "work-to-home", provided you have further tweaked the master versions only. Or they do because in the end you liked them better and continued tweaking on them.
Note if you do not include previews: you might need to tell LR on the receiving comp to rerender the previews if it contains the photos and earlier previews already - I am not sure, if LR starts off on its own to rerender them.
Thank you Cornelia (as the Pub Landlord says "Thats a great British name").
First let me clear up some errors on my part.When I wrote 1 file I should have put 1 folder.
I have tried following the instructions but run into problems as detailed :
As both machines contain a copy of the original "negatives" the info I am carrying over will be used to overwrite any previous instructions.After going to File>Import from catalogue the dialogue box shows 3 folders. I selected the lrcat folder and pressed choose. The next dialogue box offers me a choice between
"All Folders (1 Folder)" and "My Transfers" These are linked so that I can only slecet or deselect both entries.
The next box allows me to add new photos (which is not my intent) and the third box for Changing existing photos is greyed out. (Why does LR now refer to Photos when previously it asked us to think of the original as a negative ?)
One concept that I havent quite grasped is that of working in one catalogue, say, "home to work" and having LR make changes to negatives in ,say, the "holiday"catologue. After importing "Home to work" into the 2nd machine and checking that the files have been overwritten can I then delete that "home to work"catalogue?
I know you mentioned that an external drive would not work, but you did not say why. I work on 2 computers also... There are a lot of advantages to having ALL your work on an external drive and it works great as long as you have a fast one (ESATA; Firewire 800 / 400; etc.).. If you have a moment take a look at this post by David Marx on the Lightroom Lab...
The reasons I dont want to use an external drive are;
I go home mainly to relax, but, unfortunately I sometimes need to finish work in my own time.I don't wish to carry around a laptop, a harddrive, mains adaptors,mouse, phone, camera, mp3 player, or any other items which are considered to be "essential" travelling companions nowadays. A flashdrive is more than adequate and that is only carried when essential !
My external harddrive serves as my back up.
I rarely require access to ALL photos at one time and on those occasions when I do, I utilise a procedure called forward planning.
On the occasions that I require the use of a laptop on outdoor assignments I dont want want extra weight, nor do I wish to waste battery power on an additional harddrive.
I am au fait with the method you suggest and appreciate that it suits your requirements however if you take time to study my posting you will notice that I have asked for help to set up a specific working system ie using flash drive with copy and replace, and even though I have politely replied to one other person who also used your system you have taken it upon yourself to query my decision and also attempted to "sell" me on your system.
Don't get me wrong, its a good system, it works for you, it works for others, and If I had asked for "any ideas on how to set up a system" I would certainly
have seriously considered that option but by not addressing the initial specific question I regret to inform you that your well intentioned posting has simply wasted both our times.
I won't apologise for being so blunt, I'm a Yorkshireman and we are respected for 'saying it as it is'.

No regrets; and no problem for me... What I posted was 10 seconds of reading. If your time is so critical those 10 seconds of read don't compare to your arduous reply. I certainly Hope you get your issue's worked out and have a better day.
I would rather be respected than liked . Respect is gained by being honest. Being liked can be gained with a round of drinks.Who would you ask for advice, the honest guy who is blunt, or the nice guy who agrees with every word you say ? Now, bearing in mind that it was'nt I who drifted off topic, can we get back to the original discussion which asks for answers to a specific problem ?
Sorry to deliberately keep off the point, but honesty can be taken too far, and definitely was in this case; the native photo was just trying to draw out why you didn't want to follow one particular course of action. Not at all an unreasonable act, as he just might have convinced you that there was a better way of doing things in the future.
The purpose of this forum is not to debate social graces or manners. It is to discuss Lightroom and to be helpful to others. I certainly was not trying to waste your time, or anyone else's including mine. As Johnhawk666 stated accurately; I was only curious why using an external drive wouldn't work for you, and only offered a link for a good article on the topic that you might have found helpful. That did not mean you had any obligation to follow the link, and I was not trying to "sell" you on my way. But again; I don't want to waste time by drifting as you say "off topic"... I will point out that if you think such is the case you might consider editing the title of this thread and changing it to something such as "How can I work with Lightroom transferring files using a flash drive?"
Currently your post is titled "How can I work with lightroom when I use two computers?" so after all; I was really not so off topic. If taking a moment (A very brief moment) to read a post bothers you so much, maybe you would get more specific responses if you re-title your post. It's Just a suggestion, and you should respect that because I am only 'saying it as it is'.
Happy days using Lightroom. I sincerely hope you have great success and hope someone will answer your questions to your liking. Now I will remove the default e-mail notifications for this thread because I don't know about you, but I have better things to do.
Hi Geoffbubbles - Yorkshireman,
To answer your question: yes, you can delete the *transportation-vehicle partial catalogs* home-to-work / work-to-home once you have imported them on your work-machine / home-machine. Their sole purpose is to carry the database-entries from one of the *real catalogs* over to the other.
They never change your original files, they just have setting-instructions&metadata about them. (There may be the photo-files themselves as well as previews present).
And those instructions in a *real catalog*, which are present from a previous import, you overwrite by the process of importing from the transpo-catalog-part.
Myself I have experience only with a one-way set-up: one computer has the "master LR catalog", the other computer has a *2nd view catalog*, but is not intended to perform work which I would want to take back into the master catalog. But the process of exporting a portion from a real catalog via a transpo-vehicle-partial-catalog and importing that into the other real catalog is always the same.
Don't be confused about Adobe's wording: I have not found them consistent in a mathematical manner, so whenever you read "image", "photo", "negative", "file" best treat the terms as synonyms...
I would bother with previews only for the first time you create a transpo-package, assuming that the changes afterwards by new development instructions are more easily updated on the real catalog after import.
So once you consider the going-back-and-from finished I would have LR re-render the previews in the final catalog for quick browsing (Menu Library - Previews - Render standard-sized previews).
Regards from a also notoriously blunt German,
(I have never made it yet into Yorkshire, but it's now on top of my Britain-list to visit, for stunning photo scenery)
I saw your reply to the post on working with two computers. I have a slightly different situation - I would like to have Lightroom installed on two computers (in different cities) then save my catalog and phots to a cloud such as Dropbox. I would then use the Catalog and files from either computer and have changes saved on each. I would never be in two places at the same time some my only risk is that somehow that Catalog does not sync. Will this work?

It will if you are willing to upload the entire catalog and previews to Dropbox each time you make a change then download the entire catalog and previews each time you want to work on the images in another location...but the images would need to be up/downloaded at the same time. Personally, I don't think this is workable unless you net speed is super, super fast. I would suggest keeping the images, catalog and previews on an external drive and carry it between the locations.
In Dropbox the files are automatically synchronized to both computers. For example I could work on a catalogue in NY which is located on my local Dropbox folder and as I work is updated to the cloud. In this scenario my catalog would be replicated on computer "B" located in Chicago. When I get to Chicago the files will be identical.
I have read that Lightroom can't be used on a network but this would look like a local drive in both cases. Other than transfer speed, which is not an issue given that it is at least 24 hours between uses in each city, I can't see a reason that this won't work. Am I missing anything?
Thanks for you help!
