Digital Exposure Question -- Middle Gray vs Exposure At Highlights
"Chris Brown" wrote in message ... In article , S. S. wrote: Hello, DigiFotoers, I am taking photos with a Canon G3 camera. I think there is a tip out there suggesting that when taking digital photos, shoot by exposing at highlights (which will make photo underexposed), and then bring up the brightness using softwares afterwards. So I usually take pictures by Spot Metering at the highlights. This works under normal light condition, but when I tried to do it when doing sunrise, sunset, or waterfall, spot metering at the highlight always makes the dark area lose details greatly. Spot meter on the highlights and use +2 stops exposure compensation. Without the compensation, you're essentially pushing your sensor by two stops, something digital sensors are really bad at. I wonder, in both normal light condition and abnormal light condition, how about one just spot metering at the area that is close to middle gray? Does any of you have experiences with doing that? Thanks! That would work, but you risk blowing the highlights. The reason for metering off the highlights, with exposure compensation, with digital is the same as for doing it with slides - neither handle overexposure well. With the Canon DSLRs, you can generally get away with +3 stops on the brightest highlights (and RAW mode), but with the G3 you may want to leave it at +2. Is this the same a compensation for snow scenes increasing exposure or under exposing for coal(dark) scenes because the exposure meter is trying to render all to 18% grey scale. as Ive been underexposing by 1 stop to prevent highlight blow outs and have got very underexposed shots on my D70.
