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.

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.

One important reprequisite for working seamlessly across both computers by means of an external drive, will presumably be - to ensure that the external drive appears under the same drive reference when connected to each computer.

This doesn't matter for the catalog itself; but it does matter for the validity of the image paths information that it contains.

Richard this works differently with MacOS where drives have actual names that are retained.

Yes, thanks, I thought that was the case. Altering the drive reference (by which, I include naming) meanwhile, will presumably break the file paths concerned?

Windows also uses an (optional) assigned name that the drive stores, and reports to a different computer when first connected. This all navigates and works perfectly fine in normal circumstances, where file paths are not critical. But in Windows this is only ever an alias for an assigned drive letter which will not (IIRC) port automatically in the same way as the name does. My own experience is that it is better to also force this drive letter the same, because Windows applications tend to use either kind of addressing more or less at whim (it often seems).

If Mac applications are written to always respect the name only, consistently, so much the simpler and better.

I haven't tested whether LR will still respect paths using the same drive name, even when associated with a differing Windows/DOS drive letter, but would not have expected it to do so. One also has to consider other utilities, backup, etc.

This has become IMO worse with later versions of Windows, where even the exact same (physical) folder may present itself under slightly different (library) names in different circumstances - for example, "Documents", "My Documents", "(Username)'s Documents". Yet another layer of uncertainty; just to confuse longbeards who are more accustomed to the explicit and straightforward file systems of yesteryear (grin).

I use Lightroom on 2 computers, one in England and one in France. I have all my images, catalogs, keywords etc on a USB3 portable disk and I just up sticks and plug it in where I am.

I use a Windows 7 64 bit machine in both places and have the disk designated as W: on both machines.

It works seamlessly but obviously for it to work all manipulation of images must be from within Lightroom and within the portable disk.

One question, maybe Victoria would know the answer - naturally, Lightroom is installed on my C: system disk. If I were to upgrade to the new RC on my London machine, how would that affect things when I first plug it in on my France machine which would still have LR 4.1 installed? Any steps I should take to take account of the fact that my registry and so on will of necessity be different on my 2 machines?

There are no catalog changes that I know of, so it should be fine.

Thanks!

I caused myself some problems when I upgarded from LR3 to 4 in England and then took the disk to France where I had LR3 running. I'm not sure what would have been the best way to handle that but I'm sure going to have to find find out before LR4 morphs into LR5.

That makes sense glugglug.  Full version upgrades (i.e. 3>4, 4>5) generally upgrade the catalogs, but dot releases don't.  It's always worth doing major upgrades on all of your machines at the same time, but if you're ever caught in the wrong country without your installer, just download the trial version and put your serial number into that, as it's the same download.

I thought I could move my catalog to my NAS but this is the error I got:

erreur lightroom.jpg

Is there a way around that or is it that it just cannot be done?

I moved back my catalog to my C: drive and got that error:

Waited an hour and was able to start LR with that same catalog in the same folder.

Weird.

Victoria,

I just recently purchased a MacBook Pro for travel and for sitting on the couch and working in Lightroom while watching football. I'm trying the dropbox approach for syncing my catalog and previews. My images remain on my iMac. I'm trying to create the same Lightroom environment on the MBP as I have on the iMac but seem to be having issues with collections, loss of label colors etc. If I were to put it all on a external drive, thinking of the Samsung T1, what specific Lightroom files should I put on the external drive? Should I also copy the camera raw and lightroom folder to the external drive?

Thanks

On the external drive, you need the following files:

the images

the LR catalog (*.LrCat)

the preview folders

If you use develop presets, you will want to copy them to the other computer.

Thanks, ManiacJoe. What about the collection information? In my current setup, the catalog on the laptop shows the collections I set up on the iMac but on the laptop most have zero photos in them. is that because I don't have the original images, just the previews and smart previews on the laptop?

On your new computer, how did you populate that catalog?

The easy thing to do would be to just copy the catalog from the old computer. Importing the old photos into a new catalog is usually a bad idea.

I put the catalog and smart previews files into dropbox and opened the catalog from Dropbox on the new computer. I also copied the preset file from the iMac and replaced the present file on the lap book pro (after keeping the original file with Original added to the file name)

So my question is, why does the collections and color label  information not show up on the laptop? Is there another file I should be syncing or putting on an external drive if I go that route??|

Thanks

All that info should be in the catalog.

You might try syncing the catalog from DropBox again. Try using the catalog NOT in the DropBox sync folder; some versions of this type of service don't like random access files like database/catalogs getting updated randomly.

I agree, and I don't see why this isn't the answer the OP is looking for.

Like Victoria suggested, I keep all of my photos and the active catalog on my removable external drive. (I also keep two backups of this drive.)  I have LR5 installed on both desktop and laptop (which Adobe let's you do) so I can work on the photos on either machine simply by plugging the external drive into the machine.  Any changes (on either machine) are reflected in the active catalog on the external drive so nothing has to be copied over from one machine to the other.  This also allows me to designate each machine for catalog backups when using that machine.  Thus I have multiple recent catalog backups on different drives (important) and I don't have to keep track of which catalog I'm using. From painful personal experience I can verify that you do NOT want to get confused about which catalog you are using.

I get how to use an external drive with LR to keep pictures and catalogs sync'd between one computer and another.  My question is how do I actually make an exact duplicate of Lightroom, including all of the presets, plug-ins, etc., so that I have the same tools and options available on both computers.   When I add a new preset, for instance, on computer 1, how do I sync that change to LR on computer 2?

When adding files (presets, plug-ins, etc) to one computer, you will need to manually add them to the second computer. Basically you will be installing the new files twice, once on each computer.

As far as presets go, this might be one case where turning on the option of "store presets with the catalog" MIGHT come in handy. Maybe, maybe not.

Keep in mind that Lightroom is designed as a single-user single-computer product. All the suggestions here are just workarounds to that limitation.

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.

Yes Rob, agreed.  I thought that since my NAS is connected to my main computer with a 1GB wired connection, it would work well.  I guess LR detects the network connection and won't allow it regardless

I find the catalog limitation more and more annoying, I wish we had the option of having editing information in "cart files".  That way, I could temporarily move things to my laptop, do the editing on the road (let's say) and move the files back upon return.    Carrying an external drive is not really an option...

Transfer speed is plenty, it's he latency for the multitudes of random accesses to the database that causes the slowdown.

You can map the network drive as a local drive and it will work for testing. It is my understanding that some few people are actually using it this way, and keeping their catalogs backed up in case of troubles, but it would make me very un-easy.

Yes, and besides, the problem would remain for accessing the catalog from the other computers that may not be on a wired connection.  Like I said, the good old "cart files" were not such a bad idea in the end.

Thanks for reminding me Rob.  However, I would have to fire up my main computer to be able to export (before leaving the house with the laptop let's say).  Not only that, it must take a while to export a big catalog.

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/

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.

Thanks Richard,

 

indeed the difference seems to be the fact that using Dropbox the catalog file is actually stored on a local folder which is in turn replicated to other PCs (and, even more important, backed up).

Nothing more to add if not that it works perfectly for me (LR4 before and 5 now).

Thanks Richard and Paolo.  I find the concept of mapping my network drive (much like what is done with Dropbox) very interesting.  That would allow me to work from any computer in the house with a single catalog file.

By the way, if it works with Dropbox, would it work with Google Drive, Skydrive and any other similar service?

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?

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?

Regards.

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.
