Lightroom on two computers

I have Lightroom 4 on an IMac and store all my photo files on an external HD.

I recently purchased a Mac Book Pro and have installed lightroom and my main catalogue on it. I have the actual images on a portable hard drive.

How can I work on images on my desktop and then import the changes to the images on the laptop. I also wish to be able to work in lightroom on the laptop and update the changes on my desktop and main HD.

Have googled this but very confused.

I'm a guy who likes to keep all my photos from the last ten years on in a single catalog. For various reasons that I won't get into here, this is viewed by some as a reasonable thing to do. But the catalog is large. Mostly I work on my photos on my desktop machine.

When I'm on vacation, I sometimes put photos on my laptop and, for fun I might edit them a bit in Lightroom. I don't keep a full catalog on my laptop, as I don't want to use all that space on it's drive. And I don't feel like trying to export and import catalogs or trying to keep a catalog on an external hard drive.

So if I have, say, fifty images that I've edited while on vacation---what the heck, I just export them as maximum size JPGs and copy those JPGs over to my desktop so I don't lose the edits. I'm not compulsive enough to want to save the unedited state of those images, I just overwrite the old files with the new ones.

I really do not adwise you to do that. I used to resize my 3-Mpx images to fit my screen (1024x768) and save HDD space. Now, 15-years later I am stuck with overedited and resized 0,7Mpx images, that some of them already failed to open. While original 3Mpx images, thoose who somehow escaped my habbit, still holds more data than 10x15 cm print can reproduce and more fidelity to drag details from. Since new processes in new Lr keeps geting more out of SAME images. Plus as from my experience original images are fails less often than new edited one. Reason is probably that JPEG file, which is very prone for corruption, are likely safer when you leave it at one place on HDD (every copy can produce error. Error in JPEG is quickly enough to render image corrupt. edited images tend to be more fragmented than original one, ... ).
Make edits and copy the image. Having second copy is safer, for JPEGs even on same computer it reduce risk of corruption of certain image.

But if you do not care for picture to have the safe, why then bother with edting?

I recently went through some old jpg files, family stuff shot on a 3Mp Canon Ixus. I work by culling my pictures ruthlessly, keeping only the best or most unusual/ interesting ones but rarely duplicates of them (It's one of the few ways of having people be glad to see your holiday pix, 10 max). I'm an ex newspaper photographer so rigorous editing is second nature to me.

No matter what editing I do, I always keep the original untouched. One shot, of my family at dusk walking through a field of maize was a lovely picture but hopelessly noisy. LR current noise reduction is 20 times better than the specialist NR software I had when i took the shot back in 2003 and yields a still noisy but very acceptable quality result. It transforms the picture, really. I'm with Snemanje 100% here.

The best solution I have found is to use BitTorrent Sync to keep the catelogs in sync across multiple computer. The only thing you have to do is in the computer you are working pause the syncing while you are working.

Another solution is to keep both your Lightroom catalogue & your photographs in a cloud storage location (usualy located in c:\users area on a PC), this will automatically be synchronized between your desktop & laptop in the background. The biggest issue here is that the size of your pictures/catalogue directories needs to be contained within your cloud storage allowance. In my case I rarely have more than 20GB (the size of my Adobe cloud with the Photographers CC subscription) a year so plan on creating a new catalogue each year which will then be stored on my desktop & a back-up hard disk.

Thanks kid.carter. That was the question I asked just a few posts above. I did map the network drive and it did work but found I sometimes launched LR before the mapping was finished. My catalog is (currently) just over 200 MB, I guess it would be fine on Google Drive. Did you try it yourself?

Hi

You can store your catalog on a dropbox folder and share it with as many computers as you need. And it's backed up too.

There are severals tutorials around, here's one http://www.vdsar.net/lightroom-catalog-sync-with-dropbox/

Thanks Paolo67.

I'm a bit surprised to read that: I can't use my own network drive (which should be much faster I would think) but I can use something like Dropbox?

Does that make sense?

A dropbox-managed folder is no different in terms of its access, AFAICT, than any other folder that is stored on the same physical disk volume.

What your PC "sees" at any given moment with Dropbox is not all the stuff in the cloud, just the locally stored copy - as that currently stands.

The point is AFAICT, that LR wants to enjoy direct access without intermediate layers of network protocols etc. It doesn't mind using a more distant form of addressing for the image files, but the database is.. close-to-home.

Mapping a network location via the OS "under the guise of" a (virtual, simulated) local drive, with its own drive reference, may work.

I am in a similar situation.

In my case, I store my pictures on a network drive and access them from a desktop, and a laptop. I would have to move the catalog to the network drive if I understand correctly and that's not a big deal. How about the pictures only present on one of the two computers though, would they be just greyed out in the catalog? For example if I want to work on some pictures off-line outside of the house. Could I move pictures from the network drive to the laptop, work off-line, and move them back when I come back? Or would the catalog get all corrupted depending if I use the other computer?

I am a bit worried about the process since LR has a bug in the "update folder location" and will duplicate my entire network drive when I use the function to "catch" pictures that would have been moved/copied/imported outside of LR. (I think Victoria already helped me out with that problem actually)

It is my understanding that Lightroom won't let you open a catalog that's located on a network drive. Al least, I get an error message when I try that. If anyone has a work around to that, I'd love to hear it.

The simplest workaround is what Victoria suggested: don't put it on the network (use external drive instead).

If you absolutely must keep it on the network, then you'll "have to" copy it to local host before using, and make sure it's copied back to network afterward. consider LightroomStartupScript if you decide to go that route.

One can fool Lightroom into using it from the network, but it's:

* slow

* unreliable (may corrupt your catalog)

Those should be good enough reasons not to do it.

The simplest solution is to put the catalog on the external hard drive, and then you can easily plug it in and use it from either machine. There are alternatives, including using import and export to/from catalog, but they then require you to keep track of which you last used.
