I own the Olmpus C8080 and transfer the images to Photoshop CS for editing.

The first thing I do after downloading the pictures is to save them in Photoshop’s native format because JPEG images degrade during editing.

I’ve recently been given a free-standing photo printer, into which I simply plug the camera’s Xd card to produce prints. I thought I’d print some of the pictures already on my computer by transferring them back to the Xd card. I resaved the ones I wanted from .psd to .jpeg and transferred them over USB back to the camera, and this process appeared to work. When I’d finished, however, the camera said that there were no images on the card.

I contacted Olympus, who said "The JPEG files edited and resaved in Photoshop are loosing (sic) their EXIF information. Wihout EXIF they are not recognized when saved on the card again. The possibility would be to attached them EXIF again in CAMEDIA MASTER PRO (function Exif Maker) or to do it via MASTER SW (function Copy to camera)."

I’m sure Olympus aren’t cynical enough simply to be plugging their own software, but does anybody know of any other way of doing this please?

No they don’t. They only degrade when you save them, not during editing.

What makes you so sure? Actually, what they’ve told you about Photoshop is false. Photoshop will preserve the EXIF data in the file if you "Save As" a JPG. It will discard the EXIF data only if you use "Save for Web" because the whole purpose of that option is to minimize file size for web use.

Load one of your camera JPG files into Photoshop and look at "File > Info" and select "EXIF" from the dropdown. The data is there. Then, "Save As" JPG. Open the new saved file. The information is still there.

Really? I didn’t know that – thanks.

So, that means the EXIF info is lost when saving the originally imported JPEG to psd and then saving the psd back to a JPEG? And if I take the imported pic and "Save As" a JPEG, I’ll preserve EXIF info but degrade quality? So am I buggered either way?

I don’t think so. I can take a JPG direct from the camera with EXIF data intact, convert it to PSD, edit, add layers, flatten, "Save As" JPG and throughout the process the EXIF data is available in the "File Info" dialog. Opening the final JPG (converted to PSD, back to JPG) it still retains the information. Try it yourself.

I’ve tried it and you’re right. If I then send the pic via USB back to the camera the computer tells me it’s fine. Problem is, the Xd card has nothing on it. I can only assume, therefore, that the card is looking for something, doesn’t find it and doesn’t want the picture back. Most peculiar!

PS does add a little EXIF note saying it’s been edited in PS which might upset the camera. There are EXIF extraction & reapply utlities for free that would restore the ORIGINAL EXIF info if it’s really important this might work.
