I have an SLR with a fixed aperture of f/10 and shutter speed of 1/80. What ISO do I need to remember for different lighting situations?
That's helpful. What if I want to take a photo of the night sky?
You will need to use a high ISO for night sky photography. Try using an ISO of 3200 or higher, as well as a wide aperture and a long shutter speed to capture the stars. You may also need to use a tripod to keep the camera steady during the long exposure.
