So, as I understand it, the general rule of thumb is the shutter speed should be no less than the focal length of the lens you are shooting with. So if I'm shooting with a 70-200mm lens my minimal preferred shutter speed should be 200mm to keep camera shake from happening. Trouble is that light is low on that. So the solution is to bump up the ISO until I find a magic spot. I'm not happy with the graininess of the photos I get however. Besides, you want to stop motion with a high shutter speed. But at 1/250th let's say, it's too dark. How do I get around this? Is this the same thing as what used to be called "pushing" film. I never understood that, but any attributes (ISO, shutter, aperture, etc.) I can play with would be a big help.
