Hello Leonard. I am thankful a lot for your wish to help me. Yes, my native is Russian, so what! Right now I have translated my text: "Farther follows eight points of impotence" by Google Translator. It gives me in Russian exactly the same I wanted to say. What native of Google? But let's back to our topics. "Producing zero pixels" as about you say, it is not my topic, mine is about automatic preventing zero pixels appearance. Look please, my custom settings are: White Balance- auto, ISO- auto, Exposure mode- Manual, Exposure metering- Matrix. Active D-Lighting- on. Auto-focus mode AF-C or AF-S; AE-L/AF-L button is AF-On. Result: http://www.flickr.com/photos/gentlehug/8508779110/ In street photography I live in seconds, take it into consideration. Best regard, David P.S. Impotence is condition of inability to make action.
