mmeyer Posted August 4, 2007 Share Posted August 4, 2007 Hello again, I took this picture yesterday as well and I noticed the blue spots around the base of the bill and the chest. Is this simply overexposure or something else. I noticed it on a couple of others where there water droplets. # Focal length: 98.0mm # Exposure time: 0.0008 s (1/1250) # Aperture: f/4.0 # Exposure bias: -0.33 # Metering Mode: matrix Thanks MMeyer Link to comment Share on other sites More sharing options...
Dbl Posted August 4, 2007 Share Posted August 4, 2007 That certainly looks to be CA - Chromatic Aberration or "purple fringing". It normally shows up when you have brights next to darks. Generally found on lower end lenses, though some high end ones are prone to the same issue. If you shot in RAW there is a tab labeled "lens" in the RAW converter in CS2 that can help remove some of the CA. Link to comment Share on other sites More sharing options...
