say i have a dust spot on my sensor. i shot all day with it and then realized that there is a little imperfection on all my days worth of pictures at the exact same spot. is there any sort of automated process of correcting this? like, can i tell photoshop or something to hit every image with the spot healing tool at the exact same place on every image?

You'd need to create an action in Photoshop that removes it, however, the obvious thing to do is to make sure your equipment is in good order before going out and doing such an endeavor.

Another thing *I believe* is to do a dust reference shot, but I have not worked with this and do not know how to use it... I always felt this was a band-aid to the real solution.

Before I walk out of the house on a job or for a day of fun, it is easy for me to slap on the 24-70 set the aperture to F/22 and take a picture of a white wall that had a flash blasted on it. ANYTHING on the sensor will clearly show. If something is showing, the entire process takes under 60 seconds, as that is when I go and clean the sensor. I use Eclipse products specific to my sensor needs only.

Hi Chris, I have noted Jerryph's comment, and he is normally quite correct.
I am possible speaking "out of my league" as I am not up with most of the technical issues.
I only have a small camera, but just wanted to post this just in case it was a small issue such as a DEAD PIXEL, which will obviously show up in the same place each shot. I have had this, and I did individually correct each shot on PS. I have since had my camera repaired.
Just my thoughts.

I agree with Jerry, removing the sensor dirt is the quickest and best way to take care of the issue. Cleaning it yourself isn't hard at all as long as you use the proper tools. Otherwise you can spend many dollars in getting done in the shop, but it's like getting the oil changed in your car. You will have to do it again eventually.

Yea, I know cleaning the camera is the most obvious thing to do, and something that I do regularly. Say, in the chance that I missed a spec (like I did), what is the process for automating this cleanup task in PS? It wasn't a dead spot on my sensor. It was just dust that I have since cleaned up.

I found a few links that may or may not help.
