Hi, have something to ask on metering. I have been reading Bryan Peterson's Understanding Exposure and he takes about using metering where for example,
if shooting a sunset, he meters the sky around the sun and depending on the camera's exposure readings, he adjusts the shutter speed accordingly until the exposure reading is 0. Then recompose and shoot.
1. This should mean it can only be done in Manual mode as for example in Aperture mode, the shutter speed would have been determined by the camera's metering. so if we do spot metering and meter the sky around the sun in Aperture mode, all we have to do is recompose and shoot? Then if we find that shooting in this way still over or underexpose, then we use the EV + or -?
2. The above example seems to apply more for spot and center weighted metering. I was wondering if it will work for matrix metering as matrix takes into acount the exposure of the whole frame. So even if you meter the sky around the sun, everything else in the frame would also be taken into consideration. So does that mean if I use matrix metering for shooting sunrise and sunset, I dont need to meter at all cos the matrix would balance out all the different exposure settings? All I have to do is just focus and shoot?
Or lets put it in another way, if I use matrix metering in Aperture mode to meter the sky around the sun, would the exposure readings still be accurate for me to adjust the shutter speed according so that the exposure readings will show 0?
3. By the way, how does the d50 indicate whether the exposure readins are right anot? Besides the histogram , is there like a scale with -, 0 and + where you adjust the shutter spped until it should point at 0? Askign this cos I dont own a DSLR yet but getting within the next few days, so doing reading up now.
