I am currently living in Bangkok and we have a lot of sun in the day. To give you an idea - I took a shot yesterday ISO 200 f8 with 9 stops of ND filters (3 Hoya ND8's) and exposure time was 1/45 s - there is so much light that I can AF perfectly through the 9 stops of ND filters.
Using Canon 7D and 550D with various lenses. I shoot RAW and convert. I was getting some cyan/magenta on the edges of objects and had previously attributed it to lateral CA but for some reason I could never eliminate it. Going back over some previous shots (white flowers etc.) - I think that UV was the issue.
I wanted some more color in the sky and tried recovering highlights for the first time, they were huge patches where clouds were turning pink/magenta and cyan - what I previously thought was CA was actually reflected UV being transformed by my sensor into magenta/cyan. I know people say you don't need UV filters on digital and for the most part I agree and shoot with a B+W MRC 007 (Clear) protector.
Suspected it was UV and switched to a UV + Haze - it helped a bit (I think). To test I then added stacked a second UV + Haze and that almost eliminated the problem but not fully. There must be a better solution than stacking two or three UV filters?
Any ideas / recommendations?
Thanks in advance everyone
