After reading every thread in this group on metering, I felt like the first time since I have used a camera's I had a faint idea of how to at least approach proper metering ( I realize I am far from that goal but willing and able) I did an experiment and with the same light source, same distance between camera and object, same height, same angle of view everything the same, I measured the light with the internal meter of a Pentad ME Super and a Pentad KX. All same ISO setting, same shutter speed, same f stop. I used average color ( 18%) objects, white only objects, black only objects. The white only object were two f stops underexposed. The black object was one f stop overexposed. From this I realized that it is just three f stops that makes a print underexposed or overexposed. I don't know why but previously I thought that the difference in the number of f stops would be much greater.
In no way am I trying to teach anybody in this group something new. what I realize that over the years thousands of photographers must have done experiments with light using objects with different reflectance and that there must be a record of this information. Can somebody point me to websites where I can read up on these experiments and learn more about lighting and metering. Thanks in advance Denny B - This message is from the Pentax-Discuss Mail List.
