Hi Emre, I have take the first shoot from the 550d, but i known my shoot are far from perfect...
I have planned to improve this, but you pass me ;) I have compiled a test version with both preset, i can't see any real difference between them. (tested on iso 800 1600 & 3200) johannes, can you look if this are better & then use it if needed ?
