I am a huge camera newb, but I need some basic advice. I have an old nikon fg-20 from the 80s and like taking pictures with natural lighting. A lot of times I find that I either don't have enough or have too much light going on, how should I go about adjusting f-stop and shutter speed for conditions like this. Are there any other strategies? To help, here are some hypotheticals... 1) Bright day at the beach 2) indoor birthday party with low lighting Thanks.
