Hello and Good Evening.
I am using Photoshop CC on an iMac, with Mountain Lion. I have no issues with the software and it runs perfectly, so this is just a query really.
If I save an image which has Alpha Channels contained within it, following processing, when I then reopen the image, the preview of the image in the "Open" dialogue window appears as a sort of negative, almost as if it has one of the masks on it. The image opens fine though, and looks as I left it.
If I save the image without Alpha Channels, by unselecting them in the Save As dialogue window, and saving the image as a copy, when I reopen this one, the preview of the image is fine.
I'm hoping someone may have some ideas.
I have attached a couple of images below to illustrate;
With Alpha Channels:
Without Alpha Channels:
The OS is providing the preview in the open dialog - and it'll be the same in the Finder.
My guess is that you have some alpha channels in the image, and Apple still doesn't read alpha channels correctly (despite the bug reports I've sent them).
Thank you for the reply.
There are definitely Alpha Channels in the image as I created them during the retouching.
I think you're right, as I decided to investigate further and open Bridge, (which I never normally use), and the previews in that show up correctly.
So overall not too fussed about it as long as the actual image file is fine, which it is.
Thank you again.
