I use a Nikon D80, and I've found that my photos always come out really dark when it's just the slightest bit cloudy outside. I'm into equine photography and do mostly action shots, so I can't slow the shutter speed to let more light in without my pictures becoming blurry. How can I keep a fast shutter speed for sharp photos but still improve the lighting? Thanks 
btw, don't be rude about my lack of camera knowledge, please. I like photography and would like to improve my pictures but I do not claim to be (or aspire to be) a professional.
