Can you unflatten an image in Photoshop?

No. If you import a layered image into Aperture and them make adjustments, Aperture will flatten it and that's permanent on the new version. You shouldn't really import layered images into Aperture as a starting point.

See the user manual:

File Formats You Can Import into the Library

It says: "Aperture supports most image, audio, and video file formats captured by digital cameras. "

Aperture is meant to edit photos, not graphics compositions.You can import layered images and stire them or use them as a watermark, but that's it.

"stire"? Sorry to be picky, but I really want to hear what you have to say, Leonie, and don't want to miss anything.

"stire"? Sorry to be picky,

😁 that is o.k. Keith. 😁

My keyboard likes to send the key left of the one I am pushing - in this case it sent "stire" instead of "store".

Ah, I really couldn't make it out, I was even trying out my limited german, but it wasn't "hello"," yes", "no", "airport" or "bathroom".
