Red eyes removal?


(David Macek) #1

Any solution for the red eyes??


(Morgan Hardwood) #2

Chloramphenicol works quite well.

Move flash further away from camera.

GIMP too :slight_smile:

Hello,

As regards Gimp, you can take a look at G’MIC as well:
red eye-attenuation filter

In addition, you can try Digikam.
A new improved tool was added since 5.2 version:

I really don’t want to advertise (especially as we’re on open source here and the the book is not for free), but there’s a really good book about photographic ligthing (google for Light Science and Magic to find it). Sometimes you have to pay for good stuff (as I did in this case).

Having a D7000 with pop-up flash, I occasionally get it with certain subjects. My niece has big, bright red pupils in the photos I shot of her maternity shower. I tried a bunch of tools, but most were rather draconian, e.g., color the entire area gray, or somesuch. So, I wrote a redeye tool for my raw processor that allows selection of the eye center, then works its way out to a radius doing the following for each pixel:

  1. compute the average of the G and B tones
  2. if the R tone is 1.5 times greater than that average, replace the R with the GB average value.

In a working color space where no single color dominates, this works quite well to render a pupil that retains some highlight. It’s in rawproc 0.6, which I’m going to release in a week or two. If you want a compile-from-scratch adventure, you can clone the master branches from here:

https://github.com/butcherg/rawproc - the GUI program
https://github.com/butcherg/gimage - the image library, in gimage.cpp, line 2000, you’ll find the C++ function.

Here’s before-and-after clips:

Where can I download this branch?

There are various development-series builds here for mac and windows including newlocallab.

Thank you so much HIRAM!

Good technique, adapted it to Gimp. Not very hard to script, either.
