I discovered this link last week. I feel so obsolete. No need to ask Joan for photography advice. Just go to:
http://camerasim.com/camera-simulator.html
OK. Maybe I am over-reacting a little. (I learned that from my teenage daughters).
This is a very fun link. I could spend hours here. It's very easy to use. Just set:
Lighting: Dim Indoors-Sunny
Distance; 1-10 feet
Focal length 18-55mm
ISO; 100-3200
Aperature; f2.8-f32
Shutter Speed; 1 sec-1/2000th sec
There is even a "Use a tripod" option.
Then "Snap photo"
Compare what happens when you adjust distance/focal length.
Watch the meter exposure on bottom of the image. Find the same exposure, with different aperture/shutter speed settings.
Increase the ISO, adjust the aperture/shutter speed for equivalent exposure, and compare image quality.
In case this does not answer all your photography questions, I am still here-fielding questions.
Keep smiling!
Joan
