Hi All, I use a OMD EM5 and previously an E-520 I do some underwater photography and I can easily get under exposed shots (flash not fully charged, fstop too high etc etc.) I do all my U/W photography in manual. When adjusting my shots in irfanview, if I adjust the brightness there is what I am calling a 'milkiness' that appears in the shots. I have used P/S as well and notice the same thing. Anyone know what causes this is and how to avoid/fix it? This photo I have adjusted to make it 'milky'
