Lightroom Question

Sam

If I export dng (format shouldn't matter) images from LR4 to an external hard drive and give them to another photographer and he imports the images (copy) to his LR4 will the LR adjustments follow?

Good question, Sam, I have no idea.

I do know that you would need to hit command-S to save your metadata edits to the DNG prior to exporting if they are to go along with the DNG exported, but I have never actually tried this. I suspect if the metadata is saved to the DNG prior to being exported, that the new exported DNG should then have the saved editing steps within its metadata, and they should display in the other person's LR4. But this is just a guess, Sam, as I said.

I wonder how many folks know that they MUST save their metadata editing steps to their DNGs ( or XMP files ) with the Command-S step. Otherwise the metadata is still just saved within the Catalog file, and not the DNG.

One can save all their editing steps for all their files in the Library module, by hitting Command-A, Command-S - but be aware, if you have lots of files, this is going to take minutes to several hours to finish. I just did mine the other day, and with 46,000 files in my Library, it took almost 2 hours to write all the data to my DNGs.. Also when you go to back up your external hard drive holding your image files, the back up copy takes quite a while also, as each and every DNG file has to be updated. It took over 3 hours for Super-Duper to smart-update my image file back up disk yesterday.

I usually just save the metadata to a limited # of files that I am currently working on, but yesterday decided to make sure everything was up to date - good to do, but took quite a while on my quad core PowerMac with tons of RAM and eSata wired external drives.

why would version4 differ from version3 ?

as long as the other person has same version as you it should work normally

I see we've had this discussion previously......

Sorry..................sometimes I can't even remember what I had for breakfast.....or if I had breakfast.

Little convoluted but it works. I just tried it and needed to export images to a new folder then copy that folder to the external drive. Then delete the folder i just moved the images to on my computer. No way to export direct to the external drive.

No worries mate, I didn't remember this discussion either until Bas gave us the link to our older thread.

Still glad you asked. I wasn't aware that the meta-data remained in the catalog until formally copied.... So something learned...

pathfinder

Andrew, I think that the metadata is stored in the image file and not the catalog ONLY after expressly saving it is not well known. It is important to save the metadata, so that if the catalog is lost for some reason the editing work remains safe in the image files - either DNG or XMP files.

I think there is a way to have it saved as you work along in Preferences, but it slows down your PC considerably, so the default setting is only to save when commanded, not routinely as you work.

Would be nice to have an option to ask at shutdown (like the option to backup the catalog).

thats strange
if the drive has a drive-letter it should work

go to export
on top , export to ; hard drive should be selected

export location > export to ; specific folder
hit "choose" button
now you can select the drive , and folder , or create a new folder

note that your last / previous export is remembered and thus selected
this also goes for the rest of the settings
change as required , then export ( button )

Sam

UPDATE!!!

If you use the "command + s" keys this will save the metadata and Lightroom changes in a dng file. Then you can copy, share the file from your file management tools and when imported into LR on another computer all the adjustments will be there.

I don't know if this works with the propitiatory raw formats from the camera manufacturers.

The history won't follow but the adjustments will. If you use the "export catalog" process the history will be maintained. NOTE: I haven't figured out how to do this yet, but it isn't needed for my current needs.

YEAH!!

This eliminates the convoluted method of exporting from LR to a new folder, copying that folder to an external HD, then going back and deleting the folder the images were exported to.

Sam

EDIT!!! basfit.....................your right!!! This is exactly what I was looking for to begin with!!

I can export all the images from the shoot and the ones I processes or rated will carry those adjustments along with the files, and the other files will go as shot.

Sam, just curious, how are you mass exporting to a specific folder? I have been trying to figure out a fast way to export all images in a single folder, not into the original folder, all images lined up on the bottom LR browser window, to another folder. En mass. I know how to pick and choose individual exports, or even hold the control key (windows pc) to multi select, but to do them all at once, edited and non edited?? I have right clicked and looked for a select all/ deselect all key/ window, but no luck. I know you're on a Mac, but the process inside LR should be the same? Thanks beforehand to whoever.

pathfinder

CTRL-A selects all the images in a given folder (if you are in the Library module)

Ctrl-D deselects them

novicesnapper

Awesome, TY. I knew it was something simple lol. I've been forcing myself to use more and more keyboard shortcuts, guess I missed that one.

pathfinder

Keyboard shortcuts are a real pain to learn, but are also the real key to rapid use of Photoshop and Lightroom.

If you watch videos of real editing pros, they all use keyboard shortcuts all the time.

IF you save the XMP yes. You should force the issue (a full update of the DNG) including an embedded JEPG, DNG profile etc by using the Update DNG Preview & Metadata command. And yes, the format matters if your intent is to send a raw file. You can save a rendered image off as a DNG, it ain't raw.
