I've just tried to make an HDR out of three RAW images (in CR2 format), but I'm always getting strange gray artifacts around sharp edges adjacent to the sky:
What did not work, was choosing another tonemapping algo (the pic here was generated with Fattal) or another series of RAW pictures (I made three of them), nor did removing the brightest pic (+1 EV) in the series. Updating to 2.6.0 (for Linux) did not help either.
Parameters: Canon EOS 70D + EF 24–105 mm f/4 L IS; 40 mm; ISO 400; f/9; [1/20"; 1/40"; 1/80"].
What is the problem here? Thank you.
