Cool, Sheila! I never thought of my camera as having 8 rolls of film in it at once, but that is exactly what the digital age has given us
I have found that I get confused when I try to change too many settings at one time, so your advice about changing only one at a time makes sense.
Jumping around a bit here on the triangle, but I have found that I absolutely hate changing the ISO speed above 400 because of the grainy texture I get.
I will have to see if my camera even has an f-stop at 16. If it does, I didn't know it. If the sun ever shines again around here, I will have to give it a try. It's been very drab around here lately.
Thanks!
