You will lose PV 2012 edit capability, the amazing editing of RAW and jpeg files, the way that upping the shadow detail does not introduce 1/10th as much noise as fill did. You will lose the ability to lift the whites and drop the blacks, the ability to add the incredible clarity and compromise its crushing blacks by reducing the black levels.
You will lose the ability to Geotag your photos using data from GPS trackers or iphones or similar machines that generate the necessary GPX (?) files.
You will lose the ability to make books with a company called BLURB.
You will also miss the headaches and the issues, the slowness and the frustrations.
Why not use LR4 for all your new images? rather than importing all your old images from LR3.X catalogs?
There is a great deal of info on ways to reduce the lags, the issues, the slowness. YES some are workarounds, some are / rather should be unncessary, but they DO work.
I have catalogs on USB 2 drives. They work, but I'm mostly adding new images to these and I can cope with some slowness, fortunately I'm either very lucky with my laptop having very few issues.
I restart LR4 on my laptop every hour or so. So what it takes 30 seconds. I lose that every 2 edits, so its not a realistic issue. Its a FXKNG PITA that LR4 does not work properly, but fill in the bug reports on their get satisfaction forum.
This was posted 2-3 weeks ago on the bug forum http://feedback.photoshop.com/photoshop_family/topics/lr4_0_reacts_ext remely_slow but why it was not posted on here is totally beyond me. Whoever is doing LR4's marketing and social awareness is in need of a new job as a prison janitor as they are not communicating with their public.
I've been asking questions on Twitter and facebook, and posting comments - fair, but honest, and I'd recommend making noise on twitter / facebook / Google + as this is where comments will get noticed, they can't shut down threads or delete comments.
All that negativity and educated derisement will cause them more pain in the real world. This is where voices are heard and companies have to listen, or mud does stick.
Make comments on twitter using the hash tag #lightroom #LR4, you can also put these on Facebook messsages, google+ and Linkedin.
All these really make a very very strong impression on companies, they should listen to social networking and if they dont, they are so 20C.
LR 4 will get sorted, it seems to be 2 main issues - dual displays and over enthusiastic disk access - for some reason more prevalent on certain drives - whether SSD or not, I'm uncertain.
Til then, if you are going back, use your LR4 catalog for the stufff you've edited in LR4 - why not export all the most recent stuff as a new catalog and use that when you need to, and go back to the backup LR3.X catalog that was generated when you upgraded to LR4
least you can cope with the slowness of those images you worked on in LR4, but have your main catalog as LR3.x
Good luck and I hope this helped.
Everyone else, on twitter, follow #lightroom and see the noise there, and those with issues, post positive, fair but DAMMING comments so #adobe #takeNOTE and #listen to the #disenfranshised
I suspect Brett is right - that Rosalyn was talking about screwing things up by trying to get back, still I have to agree with Hamish - it seems a shame to return to Lr3 when Lr4/PV2012 is so awesome on so many photos. On the other hand, if you've tried "everything" and still no go - whata ya gonna do??? Although at this point, it sounds like Lr3 is messed up too, so maybe it's time to retry with Lr4...
Lots of ways to trouble-shoot. But I find that seeking a ground zero then working back up is often effective.
do the problems happen even with a brand new catalog with only a few photos? if not, then it was your catalog causing the problem.
If so, then its something about your system/installation/config...
Thanks so much to those who took the time and effort to reply - I do appreciate it, and I see you've given some very valuable information - including the link, which I appreciate shows step by step instructions for those of us who need it- like me. Yes...I really want those wonderful features that LR4 offers, but I realize I didn't make myself clear. Originally, it was just "slow"...importing taking many hours for a couple hundred photos, exporting exceptionally long as well. I didn't even notice the develop panel slowdowns/problems that others have mentioned. Now, it is now totally unusable, not just "slow"....it deteriorated to not opening an individual image at all....constantly displaying "loading" on the image and in the histogram area, "calculating", with no details there. The thumbnails load quickly when I click out of the individual image, but again showing "calculating" in the histogram, when there is an idividual photo highlighted. Only one monitor is used, I tried all the cache settings suggested, rebooted, catalog optimized, disk defrag, disk clean up, etc. etc.
I installed LR4, but didn't do anything to " import" photos from LR3 - there were there, and knew not to expect the old edits to convert to the LR 4 features - which was acceptable. I didn't do anything to import photos.
As I mention in my original post, I tried to go back to LR3.6 - and it won't even load the catalog now. (see my original post "I tried just switching back to LR3.6 having not deleted it and it is broken too,- a handful of previews load, then others try to load, taking far far too long. If preview thumbnails do load, they disappear when I scroll up or down, if it lets me.) I was just hoping to "fix" LR4 - I can accept some slow downs, at this point just plain "slow" would be a huge improvement.
Thanks for the suggestions as to how to give them feedback that has the potential to get noticed.
Yes, my original question was what was my risk in trying to delete and reinstall LR 4....thinking that might be a fix....but I didn't want to cause myself more problems by doing that.
So, thanks again for those who responded.
Bummer about your troubles.
Indeed Lr3 can not open an Lr4 catalog.
Did you try creating a new catalog in Lr4, and import just a few new photos? - Same problem in that case too??
I've found that relatively minor glitches in a catalog can really goof up Lightroom sometimes.
This would be a very worthwhile thing to try if you haven't already.
Yes, I created a new catalog and it is still trying to import a handful of photos for the past several minutes - stuck on the first one at the moment, so the problem continues......I once again tried to open 3.6, an the problem continues with it as well - tried rebooting again, no luck. Thanks for the suggestions, though.
Windows 7 - I was going to delete LR4, then reinstall, then chickened out since I can't even get thumbnails up in LR3.6...therefore no idea if I have functional back upwith the old stuff....thanks again for your replies. I am totally ignorant on the computer system behind Lightroom and Photoshop, etc., I only know how to function within LR, PHotoshop,etc.since computer courses weren't even heard of until well after my college years.....translation - I'm too old for this stuff! My husband checked things like whether the computer systems were bogging down with the operations, and that doesn't seem to be the case - have far more than the minimum requirements in my system. Also...I .have a 4TB server, storing my photo files. Still stuck in never never land and no way out, but thanks for trying!
Sorry Rosalyn, if Lightroom does not even work with a new catalog after re-install/re-boot, then I wouldn't know what to do, other than stuff you've probably already done - clear out preferences, previews, presets, caches, and disable all plugins...
Only 1 computer in house? If not, maybe try the other one. Even if not OK to use permanently, it may provide a clue.
Try photos on non-networked drive...
There is something in your computer system setup, or Lightroom configuration that Lightroom is not liking (could be just about anything) - your mission, should you choose to accept it, is to find out what (or get around it without ever finding out what).
Wacom tablets have caused such problems, as have graphics adapters/drivers... Also, security software and auto-backup software can sometimes interfere...........
Did Lr4(b/.0) ever work good? or never has??...
Something bothers me about what you said you did when you got LR4.
"I installed LR4, but didn't do anything to " import" photos from LR3 - there were there,
and knew not to expect the old edits to convert to the LR 4 features - which was acceptable. I didn't do anything to import photos. "
When you started LR4, did you point it at your LR3 catalog?
- If yes -- did it ask to convert it??
- If you did not point at our LR3 catalog, what did you do???
- Did you re-import ALL your photos into a new LR4 catalog?
Just your statement above seems a bit strange ???
You know...I have thought about the question that you have just posed....... I must admit I don't remember what I did - I don't remember doing anything special...........evidently I did make some choice during the installation (I somehow thought it did it automatically - sorry for my ignorance!!!) since the previous catalog from LR3 shows up in LR4 and for a short time, all seemed well. I don't even remember any problems with the develop module that others have mentioned, initially. Even now, all my old photo thumbnails load quickly in LR4 preview....but none of the individual photos load without 7-8 minutes of "loading" for one photo, and develop results in the 7-8 minutes per photo, loading. It took many hours to import into LR4 a couple hundred photos initially, and I questioned that.
You may be on to something here, when I try to return to use just LR3, the catalog has disintegrated to now only loading a handful of photo thumbnails, with placeholders for all the other photos-it seemed okay at first, as it loaded thumbnails okay, then it didn't - waiting a long time to try to let the whole thing load again, but it didn't...just loaded a few more, but, scrolling makes them go back to just the gray boxes with to those handful of photos that seems to come up regardless, or it is locked and doesn't let me do anything.
I had minor problems with slowdowns with LR3 on occasion, but it was still very usable. So....I hope my response makes sense. Thanks so much for trying to help - I really appreciate it!
I installed a trial copy of LR4. During the installation process I thought it had stopped and after waiting about 5 minutes it opened and all my folders and collections were displayed within LR4 identical to my LR3 content.
I had assumed that LR4 would install and then give me the option to select the folders and collections that I wanted to 'Update' to LR4. (I didn't select to import my LR# content upon ionstallation)
Interestingly after a complete backup of LR3 I chose then to uninstall LR3. After a reboot and re opening of LR4 it was very slow opening in the first instance but then was slow re acquiring but now has some 60,000 imageswhich appears to be all of my LR # content.
Hope this helps
Old & Weary.
Thank you for clarifying.
I'm not sure what to say, except maybe the difference in behavior that you and I noticed is due to using the default catalog? (which I don't - and had in fact, deleted it).
Or, were more than one catalog converted automatically, or was a non-default catalog converted?
Interesting that Lr4 was slow to open after uninstalling Lr3 - I would have expected no connection... - shows you what I know .
