I've been working on a photoshop design with lots of layers. I merged them and saved it as a jpg in order to email it to someone. I thought I'd saved it as a separate document but it looks like I've simply merged all the layers and now it's just a small jpeg. is there any way to restore the layers and get it back to a photoshop document?!
Oh no... in the future when you have the layers and want to save a JPEG just go to File>Save as> JPEG which saves a copy, or File>Export>Save For Web.
Both of these options keep your layers which you need to make changes.
Your only hope is that the file is still open, and was NOT closed, and you can go backward with Command>Option>Z (control>alt>z on PC) or go to your History Panel (Window>History) where you can back up to an earlier point in the file.
Good luck! Hope this helps!
This was just up in another thread.
When you save a layered file as jpeg, a copy is saved out. The layered file is still open and unsaved. You must save the layered original separately from the jpeg copy - if you just close it, it's lost.
