I also agree with Linda. Perhaps stopping down a bit would help as well.I know this blossom is small, as we had a huge orange one in the yard in Florida.
Agree with Linda.Problem is probably some oversaturation in the reds.In DxO this can be cured maybe also in CS6 in the red channel but I did not yet try that.
Thats beautiful and vivid but I'd like to see the individual petal/leaves more deliniated. That color makes it all blend together someone. But again, still very pretty. Linda S
