Does DPP edit RGB photos?

I am trying to get my software to get some dust spots of a ton of pictures I took. I go into editor and use the stamp tool, it gets rid of them but I can't get it to batch edit the rest of the shots. These weren't taken in RAW so does that matter?

If I understand correctly, you want to stamp out sensor dust spots on a photo, and copy and past those stamps on other files to save time.

DPP won't do this with any file format as far as I know. Adobe Lightroom will. I don't know about other applications.

I noticed you have an XTi. Yes, DPP will do this in batch mode. Lightroom is not the only answer. Look in the help screens on DPP, and try to learn how to use the dust mapping feature in the XTi. Basically, it involves taking an image if the "dust", then placing it into DPP to use as a "mask" on all images in batch.

What I don't know is if it will work on jpgs.

Sorry I can't be of more help.

You can, in DPP, do a dust cloning to a jpg and copy it to the clipboard, but you cannot batch apply it to a group of selected jpgs. You have to use the Next button in the Stamp tool to scroll through them and paste it individually to each one.

Yikes! doing 350 images one at a time sounds too much like work.

Rocket blower

Both DPP and LR can 'copy-paste' dust cloning.
In both, chances are it won't work too well, because detail gets smudged on some images.

Ok, should I go ahead and give it a good shot with the rocket blower each time I get ready to take pictures?

Nah.
I shoot in low light, so wide open aperture a lot. Not too many dust visible then.
If I have a 'regular' shoot, I'll take a test shot befor I go: f/22 or so, shoot a white wall. *If* there is dust, I'll clean the sensor... (Rocketblower first, Sensor Brush second) Works for me.

Download a copy of Lightroom and give it a try. It's a 30 day trial. You'll come to like it alot.
