I recently bought a Nikon D40 and I've gone through the manual and have learned how to take a manual exposure and learned some of the other functionalities of the camera.
I'm trying to understand the concept of aperture, shutter speed and ISO. I got some books, went on the net, etc., I get the gist of it but don't fully understand it. I was hoping some of the more experienced photographers could help me out.
I also don't understand what you're supposed to adjust your ISO to - does it depend on the lighting? When do you know when to change it? Same question for the aperture...I'm not sure when to change it so I leave these 2 constant and just change my shutter speed. I totally don't get depth of field. Just feeling overwhelmed and lost.
Any other tips for a beginner would be most welcomed.
Thanks!
