I put together a small tool to adjust the green cast in Sigma images.

You can download it from here:


Here is the fish photo with red vignette brought up:

I don't have a Sigma camera (yet) so there aren't any image samples.

Greenfix will open JPEG, PNG, and TIFF, but will only save in JPEG and PNG. JPEG quality is fairly ordinary, so I would recommend saving as PNG.

The image scaling is the default in Java so it might look poor on screen, but won't affect the output quality.

The algorithm assumes a quadratic fall-off from the centre. The sliders determine how quickly the fall off occurs. Green and blue sliders are also provided.
