well i am pretty new at taking pictures and i am wondering how the ISO works and the aperture works. i have a couple example pictures. the first one was in the shadow of the mountain and the second one with in mid day which mean tons of light. And tell me about the lighting and what the ISO and aperture have to do with that. and it would be nice if someone will tell me a good ISO setting with a high shutter speed of maybe 1/1000 of a second. thank you very much. i have a canon eos rebel g 35mm film

Sorry about the huge pictures

you may want to pick up a book on understanding photography to get a better grasp on how film speed, aperture, and shutter speed work in combination. ISO (film speed) is how sensitive the film is to light. The higher the iso, the more sensitive, so the film does not need to be exposed for as long to get a properly exposed photo. So you can use faster shutter speeds. The shutter speed is how long the shutter on your camera is open for. The longer it is open, the more light gets let in, but the more likely you are to get motion blur. Aperture is the opening of the lens. a small f/ number essentially means the lens opens up bigger, to allow more light in. So again, the larger the opening, the more light, meaning you don't have to use a long exposure. Many people prefer to shoot with their lens wide open (smallest f/ number) to get the fastest shutter speed. It's a common practice in sports photography. Another reason for this is that the wider the lens opening, the less depth of field there is, meaning there is less of the picture that will be in focus. If you are at f/2.8, your subject will be in focus and anything on a focal plane behind or in front of them will not be. f/22 will get the entire picture in focus (normally).

So there is no specific good iso/aperture/shutter speed for any given camera, it's really all dependent on your vision and what you want your photo to look like. Generally the sweet spot on a lens (where it will provide the sharpest photo) is two stops down from wide open, so if you are shooting with an f/5.6 lens, its sweet spot will be f/11.
