A tool for automatic histogram analysis...

[Dralt]

Hi,

I am looking for such a tool. I better describe what I mean on the following page:

Any suggestions?

While it doesn't have quite the degree of automation it sounds like you're looking for, the Camera Raw interface for Photoshop CS2 sounds like it's pretty close to what you're looking for. You can load any number of Raw files at once, and it can visually show you the clipped areas (your first two examples). Adjustments are made via sidecar files, and no Raw image data is changed.

Hi there, Dralt, welcome to RP.

For some time now I've been thinking about doing something like that in javascript - I would also be interested to know if this exists.

However.....I'm not sure if I'd do this fully automatic. If you let this go by itself, you'd probably lose the best shots of all. Just because there's a lot of pure black, or pure white doesn't always mean that the photo is lost.
That's why I'd imagine something semi-automatic - sort of.. look at the image and push a button.

Like I said, interesting to see what other people have to say.

Thanks, Doug.

Yes, Camera Raw is what I use today. However, unless you have gigabytes of memory to play with, it's hard to open more than a few files at a time.

My search is on...

Rô,

Thanks for the welcome!

I share your concern fully. I would not use such an automatic tool to discard any file.
Programs are not that good at artistic interpretation.

I updated my page to highlight your comments:

I could indeed write a CS script that will do what I described.
