topic Why do I get lots of noise in my photos on the D30 at long exposure times with 100 ISO speed? Help! in EOS DSLR & Mirrorless Cameras https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Why-do-I-get-lots-of-noise-in-my-photos-on-the-D30-at-long/m-p/37171#M4505 <P>So I'm using a Canon D30 (3.1 megapixel). My ISO speed is set to 100, but when take phots at very slow shutter speeds I get a lot of noise. And I mean a lot. Can anybody help?</P> Sat, 17 Aug 2013 21:44:30 GMT Monzer 2013-08-17T21:44:30Z Why do I get lots of noise in my photos on the D30 at long exposure times with 100 ISO speed?

Long exposures heat up the sensor and generate more noise.<BR /><BR />When I do imaging (lots of long exposures) the sensor will get quite warm because it doesn't get a chance to cool off much between images.
