Re: [darktable-user] How to remove red flare from photo
Hi thokster, I didn't know that was possible. It works now. I was able to get rid of the flare in the image by taking the steps that Stéphane described. I learned a lot today. Again, Tanks to all!

Re: [darktable-user] How to remove red flare from photo
Spot removal alone is painful if the flare covers a large area. Another thing to try is spot removal with blend -> uniformly -> color, to pick the color from another part of the image but keep the contrast info. In this case, it removes the red but unfortunately leaves an overly light area, which could probably be corrected with contrast/brightness/saturation and a drawn mask, but I'm not getting so good results. - Original Message - > I would work with spot-removal. > > On Sun, Aug 28, 2016 at 12:42 PM, Jos wrote: > > > Hi, > > > > I have taken a picture from a sun set with my wife and son in the front. > > In the picture there is an annoying big red spot.

Re: [darktable-user] How to remove red flare from photo
Not perfect, but depending how large this clip is in the main image you could try a quick and dirty adjustment using the 'color zones' module to adjust the red hues closer to the colour of the sweater. I included a quick hack that I did, combining saturation, lightness, and hue tabs to reduce the effect. With more patience you may be able to produce a slightly better result.
