I have one for a challenge

I have rolls and rolls of Ektachrome that I recently scanned. While working through them several dozen rolls that were on a specific trip through Europe have an odd spatter effect. Using CS5, Dust & Scratch at 5px seems to clean some of it up, but muddies the images considerably more than I like.

Anyone have any ideas for something that can be used in BATCH to clean literally hundreds of images?

GWild55, Welcome to RetouchPRO
Hope you enjoy your stay here and make lots of friends.
Poke around, have fun!

Dust and Scratch does a pretty good job... you just need to use a mask.... Don't know of any other shortcuts

Re: I have one for a challenge

That looks so much better than any of my attempts. So - I'll bite. How did you create the mask?


ps: assume I'm an idiot with CS5... and that that sample is only only a 500x500 crop of a 5000x3000 image... and there really are hundreds of images - 153 in this single folder I'm working in now, and there are about 50 folders of topics. If you are suggesting a manual paint the spots mask, that won't be practical for me.

hello !

unfortunately there is no "general" method you can use on 153 pictures (like a batch/action). you have to do some manual stuff on every one of them

Rats - thought there might be some trick to exporting a 10px mask of the filtered areas, then apply the 5px filter to the masked areas,

Re: I have one for a challenge

You can create a mask using 'difference' mode.

Use any noise removal filter on a copy of the background layer, then set it to difference.
Stamp visible to a new layer. Convert layer to b/w and use any adjustments necessary [levels/curves, etc] to isolate the difference only [the spots.]

Use this as a mask on the noise removal layer.

This still isn't hands free, but at least you don't have to patch each little spot.

Re: I have one for a challenge

The spots are mildew, and different from one photo to another.

Yes, a mask would have to be made for each scan, but at least each spot wouldn't need to be patched. It's a compromise solution.

Re: I have one for a challenge

Dust & Scratches in Lighten mode thru a difference mask gives a not too awful result and could probably be actioned fairly easily for batching.

I don't think the spots are mildew. Much too uniform across dozens of rolls of film stored in various ways (boxes to trays). I suspect it's actually from a special x-ray like scanner my film had to pass though once upon a time at an airport far far away. And, did I mention they've always been there?

Here's a sample of fungi on Kodachrome.

One that is a faerie ring :~)

And a more typical pattern
