Cleaning up dust spots in DSLR video with Photoshop's healing brush
on Dec 8, 2012 at 4:52:05 am

Help...I'm editing DSLR video, but found that there was some crud on my sensor that left dark spots visible against light backgrounds (like the sky). I know that I can go frame-by-frame in CS6 Extended and clean up the spots with the healing brushes, but since they're all in the same spot on each frame, is there a way to do the healing across all frames? I can't find an intuitive way to do it...would appreciate any suggestions.

Thanks!

Mark

Hmmm, tough one. First, of course, either clean your sensor or send it off to be done as this will get rapidly tedious and worse over time - eventually making your camera unusable.

First off, FIND all your spots. This is a pretty good article: http://photographylife.com/how-to-spot-dust-on-your-dslr-sensor

2 ways:

1) create the spot fix as a development setting in camera raw (using ONLY the spot fixes), load your pix directly in camera raw and then apply the pre-made spot fix (use a sample image from the above article to try creating one). Remove spots that aren't needed. Voila!

2) Make an action in Photoshop - basically, open a new image, start recording, place your spot heals, stop recording. When you open a new image, just apply the action. This will require every image to be the same size, of course (for example, my pix out of my camera are 5184 x 3448 so any corrections for photos would have to be that exact size).

I think the better way is the development setting in Camera Raw/Bridge.

Thanks...the spots developed while I was in the field shooting, and I couldn't get the camera cleaned until I got back home. Trying to salvage the video and make it as clean as possible. It wasn't actually a dust spot...the technicians advised me that Canon DSLR's have a nasty little habit of throwing minute drops of lubricant off the shutter mechanism over time, and this is the second time I've had a dark spot in the same place that needed to be cleaned.

I'll try these ideas on a clip...was able to clean them up frame by frame in the final output over the weekend with no loss of quality.

Thanks!

Mark
