Long exposures produce some of the most dramatic images. But if the exposure is too long, the camera sensor may heat up, causing unwanted noise. Don’t let this stop you from doing long exposures – if you love long exposures, then do long exposures – just be aware of how your camera handles the long exposure time.

What is the difference between noise reduction and color noise reduction?
