Unmerge layers

[Copy link]

Post time: 2013-2-27 22:11:11 |Show all posts
I made some adjustments on a background copy of my layer then merged visible layers before saving as .psd.  Now I wish to make some changes to the saved file.  How do I unmerge the layers?  I am using Photoshop CS

The snapshots are retained as long as you don't close the file.  Also, the state the file was in is saved when you click on that particular snapshot.  That way you can save your work as you work, and still be able to rollback.  However, save and close the file, and yer all done.

i usually save a tiff or psd un merged just incase for that very reason... Ill export a JPG for sharing or printing, but ill always keep the original file, even if i never plan on going back to work on it...

Or the Snapshot.

PSD does not save the history.

There are times when a merge or flatten is absolutely necessary to continue.  What I do is create a new snapshot in case I might want to go back.  You can do this from the flyout menu on the history panel, or check the Help for 'snapshot'.  I usually create three or four snapshots if I'm trying something different, that way I can quickly compare the differences by switching snapshots.  It's a lot easier than toggling visibility of combinations of layers.  As far as leaving the image, I'd save an unflattened copy as something like 'ThisIsBeforeFinalSharpeningUnflat.psd' if I thought I might want to go back.  When your all done, you can delete it if your satisfied with the results.  I generally only archive flattened tiffs and the source raw or jpg files, but while I'm still working on a shoot, there may three or four copies on an image in various states.  Think of it as a term paper, you'd have several drafts, and a final version ready for public.

leave untouched, unless you never want to go back ' re-edit.
Merging is good if you need to sharpen all the layers in a shot, but (1) always unmerge in History before saving the psd, or (2) never say yes to 'Save the file?' before closing it.

Maybe my question should be:  What is the best thing to do with all the layers created during editing?  Merge, flatten, leave untouched?

I only maintain unmerge layers.

Let me see if I understand.  If I close the file the history get lost.  Not sound too dumb, I thought saving a file as .psd saved all of that stuff?

As above it's not possible to do it from a saved file unless you still have the history available (i.e. you have only just edited it and not closed it). Start over from your original - which you did keep didn't you?

If the history is still available, go back.  Otherwise, start over.
