Default Re: Understanding Exposure

For this series of band shots, I used aperture priority, I believe, because the values changed so quickly. It was a little after 3:00, sun was coming down pretty hard. I had little choice of the angle from which to shoot. I either used evaluative or center weighted metering, I don't remember which one, I would have to look at the EXIF. No way would I have been able to use flash on these pictures. I could only go to the edge of the track without costing our band points so most of the shots were picked off from quite a distance. (Just looked at the EXIF: I had the zoom extended all the way to 200mm to get this shot...flash would have been incidental.)

You are right...I still do not know how to read a scene. I did the test with the white towel to give me a basic idea of what a stop looks like, but reading that in a scene is another story. I need to just go outside and do some tests in the 4:00 sky. Test, test, test until I know what I know. Time is hard to find right now.

This is really hard for me to understand as well: If I meter for the sky, and then underexpose the sky by 2/3 to one stop, then I am making the sky darker. Jay metered the sky at 200, but then changed his shutter spedd to 160. Slower shutter speed...which means he overexposed according to his reading to lighten the sky. My picture was taken at 3:30, Jay's taken at 6:19, if I read the EXIF data correctly. I have to accept that I will have a difference in the richness of the sky with those times in mind.

Glenn: Lovely shot. Unfortunately, I got involved with photography after film so I do not know how to expose for transparency, medium format, or even film correctly. I have been asked, "Think of what you would do to expose for transparency" but I have never exposed for transparency. I did used to shoot with tungsten photo lamps, a blue filter, and an old Pentax K1000 some 20 odd years ago...but I let the camera do all of the metering. I never second guessed the camera meter.
