Ciao,
the more the images the more I will have to deal with artifacts from blending sky and sea, I tried in the past, to get back from the shooting spot I have to climb 300 steps, believe me, I tried it all, I did HDR, shot same focus plane with three different exposures then blend the three HDR, did 5 focus points and so on but there always are side effects and at the end the simpler the better.
I can use PS only to align the three exposures as there is focus breathing no matter how good the lens is, it's a tiny bit only on the closest shot but it's there, after than I can create masks and manually add or remove to make the perfect blend but it takes literally ages, I am investigating a way to have PS create a mask for the background image, the rock along with sky and ocean and then two more, one for the left to first third from the left and one for the remaining and see how it looks but as of now I am working on my 14" laptop screen and it's a pain.
Grazie
