Fixing green tint in image

[Matija Kogoj]

Hello.

The panorama outputs with a consistent green overtone that I would like to get rid of in the software.

I guess it's about the Exposure tab or Photometric optimisation but I am literally guessing; I've no idea how to multiply my hand to get a proper white balance.

White balance options in Picturenaut and LuminanceHDR are out of the question as they change other aspects of the image.

Images will be accessible for 6 months.

So far trying to change white balance in Photoshop proved annoyingly impossible for a 32bit image so I'd like to avoid trying that.

Thanks.

I, uh, failed to mention that *some* of the input images already had a green tint.

I suspect it has something to do with camera response curves, but regardless there should be a way to bring the outliers to normativity instead of alienating the rest.

(alienating? get it? little green men? No one? Okay...)

The Hugin photometric optimiser will try and equalise the colour balance, so a green tint in one photo will result in a slight green tint over the whole panorama.

To fix this you can enter red, green and blue parameters for photos directly. Or just use the 'grey picker' in the preview window - click on objects that should have a neutral colour, such as clouds or white painted objects, and Hugin will rebalance all the photos to make them actually neutral.
