S3IS Exif data and Photoshop CS2

[Rock Lobster]

Does anyone know if there is a way to stop Photoshop CS2 stripping some of the camera exif information from my pictures when I edit them ?

1) edit a copy not the original.
2) I use Photoshop CS it does not strip the exif.

Photoshop never deletes the EXIF data for me.

How are you saving?

I never edit the original picture I make a copy first and edit that.
I saved it as a JPEG
OK This is what I did, I noticed that some of my pictures had a lot less exif information than others, then i realised they were all pictures I had edited in Photoshop CS2 so I did a test.
I got a new, unedited picture from my camera and I opened it in Photoshop. Without editing it in any way, I then immediatly saved it with a different file name, using "save as" from the file menu, as a standard baseline JPEG, at maximum quality (11 on the scale)
I then opened both the original and the copy in Canon ZoomBrowser EX to view the exif information and sure enough the copy I had made in Photoshop had a lot less exif information than the orginal.

The exif fields that existed in the original and are now missing from the Photoshop CS2 copy include:

Shooting Mode: Program AE
My Colors Mode: Off
Light Metering: Evaluative
Exposure Compensation: 0
ISO Speed: 80
Lens: 6.0 - 72.0 mm
Focal Length: 8.3 mm
Digital Zoom: None
IS Mode: Shoot Only
Image Quality: Superfine
White Balance: Auto
AF Mode: Continuous AF
Contrast: Normal
Sharpness: Normal
Saturation: Normal
Drive Mode: Single-frame shooting

Not all of the exif information was stripped by Photoshop.
The exif fields that still remain in the copy are:
