19 & 20 Continued
First i measured how many watts of light i was getting in different areas. I started by taking a picture of my Wesco cup in the following light levels:
#1 .26 for 30 seconds (next to the building, this was the darkest i could find)
#2 .87 for 30 seconds (it was about halfway between the building and open sunlight but still in shadow)
#3 1.07 for 30 seconds (direct sunlight)
Picture #1 was basically perfect. i got really great deffinition between dark and light. #2 was not as clear and it was a little fuzzy but it was still pretty visable. #3 was very dark and it was pretty clear that the film had been over exposed. So the next day i decided to work on the exposure times for different light levels. For the in-between picture, i did 20 seconds and i was pleased with the results. I decided to do about 12 seconds for the object in direct sunlight since there would be more sunlight and from previos observations it seems that with more sunlight, you will need a shorter exposure time. These were my final results:
#1 .26 for 30 seconds
#2 .87 for 20 seconds
#3 1.07 for 12 seconds
The more sunlight you have in contact with the object you are taking a picture of, the shorter the exposure time should be.
