On to page four of the shooting menu. Long exposure noise reduction. When you shoot a long exposure like a 30-second exposure, and you have this turned on, the camera will process that image to try to clean up any noise because noise can happen either high ISOs or under long exposures. I've always wondered how much good does this do? I always like to throw the cameras through a little test. I do a 30-second exposure, shooting jpeg, just a normal exposure and see what I get. I really don't get too much noise, and then I turn on the noise reduction, and I really don't see any difference. I have not seen much difference at all in the built-in noise reduction on this camera, and so I would turn it off because it's just wasting your time. If you shoot a 15 second exposure, it's gonna take 15 seconds to process it. I say don't waste that 15 seconds if it's not doing any good. Test it out yourself, see if it works in the situations that you're shooting, but under my testing, it's just not doi...
ng much good. High speed ISO noise reduction deals with reducing the noise when you're shooting at higher ISOs. Now this is a completely different ballgame than what we were talking about in the last slide. So, same scenario, in this case though, we're shooting at high ISOs. If we're shooting at a very high ISO, we're gonna get noise on our image, especially at ISO 12,800. The camera has four different ways of reducing noise, kinda a low, medium, and a high setting, and there is a multi shot. Low, standard, and high ... The high setting is gonna correct for a lot of the noise, but it starts to lose some of the edge sharpness in our subject matter, and so I don't know that the high setting is a good option for most people in most situations. I think standard or low would be a better option because you can also do this after the fact in postproduction software. Now, the camera does have a multi-shot system that'll do the best job at reducing noise, but you can only do that with subjects that are stationary when the camera is not moving cause it does shoot multiple exposures to get that one shot. It's a very special, be maybe for landscape photography, architectural photography, or maybe product photography. Standard or off is where you're gonna probably have this high ISO noise reduction. Dust on the sensor is a problem with digital cameras because it's gonna show up as black spots on your photograph, and it's not going to look good. Having the camera's automatic sensor cleaning system is great. Being able to manually clean the sensor is another good option. A third option is to let the camera fix the photos for you. What happens with this is that you are to shoot a white piece of paper and shoot it at F22, so you get lots of depth of field, so you can really clearly see all the spots. Then your camera will see how bad the sensor is in its dirtiness, and then it will correct for that by cloning those out on subsequent photos. Now the downside to this whole system is that you need Canon's software to make this work. You're gonna need to shoot a test photo out in the field, and then you're gonna need to apply that to your other photos. How you do that is gonna be in their particular software that comes with the camera. I'm not gonna go into the details of it. It's a little bit of a troublesome chore that you don't wanna have to go through, and so I recommend just trying to keep your sensor clean through the other two systems as much as possible.
