Pink in sky

[mknabster]

I'll try to explain this the best I can, if you need me to upload an image, I will. I'm noticing that with certain types of skies, like today it was overcast, and another day it was a sunset, i'm getting pinkish highlights in my tone-mapped HDRs in Photomatix Pro. If I up the white point, they go away, or if I change the light mode, it will go away, but if i want a specific look, it will have this pink in it. How can I get rid of that, or is it just with the type of weather I was having?

I've had the same problem recently and was unable to remove it in Photomatix no matter how I adjusted the sliders. However, I saw a video on the subject today which discussed it and stated to remove it prior to tonemapping during the processing of the HDR. This video assumed you are using Photoshop to process the HDR and Photomatix to tonemap. During the HDR process when you have the original HDR review screen you should should be able to see the color artifact in the image and can remove it by unchecking one (or more) of the files on the left which comprise the image. Often times this will be the over exposed image. I don't process my HDR's in Photomatix, so don't know if there's an equivilent opportunity. I did try this on a shot earlier today and it worked, but in that case the colors were due to cloud movement during a long exposure. I haven't tried it on the images that gave me trouble before. Hope this helps.

Why don't you use Phatomatix to generate the HDRs? I have been doing everything in the program, never thought about doing the HDR in PS, then using Photomatix for the tonemapping.

I own the Photomatix plugin, not the full version so in my case I have to process in PS.

Oh ok, I have the full version then. I can't get rid of that pink though within Photomatix. I did process it though, then just cloned it out, but for some images, it unfortunately don't work too well.
