I've noticed this before and I don't know exactly when it happens, with what module actived, but it seems to be after having activated the haze removal tool.

When I rotate the image just one step (with the mouse wheel), the image darkens or lightens a little, depending on which way I move the mouse wheel. Attached are two screenshots where you can see the history stack, the rotation degree and hopefully the difference in the image.

I repeated the steps and after each activation I rotated the image. Nothing happens to the image lightness, except when rotating after I had activated the haze removal module.

Nice module by the way! It can really improve an image taken with a long lens.
