Thanks so much. Using a Canon SX 50. If one is shoots an animal walking, trotting in bright sunlight and uses the 'Sports' setting will the camera automatically adjust the ISO so that the image is not grainy?
It might but I would not count on it doing so every time.
It would help you to get out of the preset modes and take more control of the choices the camera makes.
If you use the "Tv" setting on the dial that is "time value", which on most other company's cameras is called "S" for "shutter priority". Basically you set a shutter speed fast enough to do what you need, and the camera will adjust the aperture bigger or smaller to achieve proper exposure. Then experiment to find the lowest acceptable shutter speed to avoid excessive blur. Will 1/400 be fast enough? Or 1/640? Only go as fast as you have to because going too fast will waste light and will require the higher ISO's to make a correct exposure.
Also set your ISO to something like 100 or 200 and try to make that work. If you really need to, you can set it to 400 to get a faster shutter, but you will see loss of detail and some noise by 400.
As for noise, if you shoot in RAW you can combat noise better in post processing than you can in JPG.
Side note: If you practice smoothly following the dog with the camera (panning) you can use a little less shutter speed (and thus lower ISO) and get a look that implies motion, with the head basically clear but the legs a little blurred from their fast movement.

Why do so many people say "FER-tographer"? Do they take "fertographs"?
