Originally posted by JHawk93 I have a K-x and just got a Sigma 18-250mm lens for a trip to Haiti. I plan to be taking many photos outdoors of people, scenery, etc. What is the optimal ISO setting to get full rich pictures?
As said, in bright lighting conditions, keeping ISO as low as possible is a great idea.
BUT -- if you want to get those rich pictures, at night, indoors, in shady settings, you will want to become adept at using higher ISOs when needed. It is that or leave a lot of pictures behind. It might be worth learning about the kind of noise your camera gets at high ISOs in low-light conditions. Some noise isn't as bad as other noise, as with grain in film. It could be that one of your most memorable pictures, pushing the camera to its extremes will be full of noise, but the image will be such that no one looking at it is going to complain about that. The picture will be taking their attention elsewhere.
