I "tried" finding a similar thread on this subject but either I've used the wrong words for the search or there really isn't a thread on this subject.
I had recently some major sensor dust spots on my EOS 1D Mark II. Now granted, I could see some of them when I was working on the image in Photoshop, yet I couldn't see some of them when I uploaded some shots and they were rejected due to dust spots.
How do you use Adobe Photoshop CS2, to find sensor dust spots? Any particular work flow, or action, filter, etc.....???

Note that you have to shift back to the normal view to clone the bastards out - you basically can't do that in Equalize view although there is a way around this.
It's all described in detail in Fergul's workflow which is linked to from the upload pages I think. You should probably digest the whole document.

Hi all
As Ruud mentioned, moving the image left/right quickly can spot them. Obviously this only works if the image is bigger than your screen.
This is one of the processes I use when screening.

An action to remove dustspots will be presented in the new rejection messages that I'm working on, hopefully this will help many people get rid of dustspots and thus reduce rejections.

Tim,
Are you saying that you and/or someone else on A.net is making a Photoshop action to help us reduce and eliminate the sensor dust spots? That would be great.
Speaking of that, out of curiousity, are there any actions that users of Photoshop are currently using in order to process their images for better acceptance on this site? Would be curious to see what actions are out there for useage.

Ok and here it is
-Create a “Duplicate Layer
-Equalize the image. Image->Adjustments->Equalize
-Dustspots should now become visible. Now select the original layer (called background) to work on. Use the “clone stamp tool” or if you have Photoshop CS2 the “spot healing brush tool” and remove all dustspots.
-Delete the layer “background copy” (which we created earlier”
-You should now have an image free of dustspots.

Hi all
No action to eliminate dustspots will ever become available.
Photographer 'pre-screening' is required for this. I know it's a pain in the ass but one of those things that digital photographers need to do now.
Always 'standard' to sharpen an image. Now it's 'standard' to check for dust spots.
Until The Boss rules out dust spot rejections we will all have to check

Just keep your sensors clean. I don't want to bother with dust spots, it's annoying and time-consuming. I keep my sensor spotless and enjoy doing other things while you are playing with your cloning tool.

Quoting EDDL (Reply 15): Just keep your sensors clean.
Living on mother "earth", it's not always possible to keep the sensor clean (although that would be ideal...), certainly if you change lenses very often! It's of course better to prevent (cleaning the sensor) than remedy afterwards (using Photoshop). I check by just shooting a picture with high aperture number (i.e. small aperture) of the blue sky and then - if there are any dust particles on the sensor - the dust spots show up (equalizing is then in most cases not even necessary). If several show up, then it is cleaning time!! I have done it already several times myself, and it is not that difficult (I use a special fibre-brush from "Visibledust", called the "Artic Butterfly").

Thanks for all the tips/hints.
Still curious if there are any Photoshop actions that people use on this forum to work their photos ??
I know Colin Wok (I think that is his name) used to have some actions when digital was first introduced. Does he or others still have actions we can download somewhere?
