View Full Version : 300D - at what ISO do you get noise?

For current and past 300D users, in low light settings when you need a relatively fast shutter speed, at what ISO do you start to see objectionable digital noise? Recently I felt that noise was there at an ISO of 400.
Thanks

On what type of lens?

Depends on how hard you look. You can see noise even at ISO100 if you go pixel peeping, on the other hand I have got perfectly good shots at ISO1600 if the shot has been well exposed. Remember, an image which appears noisy on screen at high magnifications often still produces an excellent print.

The lens was a Tamron 2.8 28-75 Di.

As nitsch mentioned, the mount of available light affect how noisy the photo is. The more light available the less noticeable the noise is. For example, at say 800 indoors you'll see a lot of noise, while a well exposed pic outdoors at the same setting will hardly have any noise (ok maybe a little).

RawShooter has some nice noise reducing functions built in. I really like that program!

I do most of my live band photography at ISO 400 to 1600. Noise is present in all shots. There several noise cleaners available, the best emulate film grain. Problem is no one utility works for all. Usually the captures with the "loudest" noise have the greatest contrast in my experience. These make excellent candidates for monochrome conversions. Neat Image, Noise Ninja, noise reduction in Rawshooter, even NR in ACR all have worked in different situations for me in the past.

It all depends on what you are going to use the image for. If you are to print 4x6 then you might get a decent looking print even at ISO 1600.

Exposure! Be sure to expose properly. Even when shooting raw, I fudged up a shot @ ISO100 ... completely underexposed... there was noise everywhere!

Now I properly exposed one at (hacked) ISO3200. There was hardly any noise! What there was, was removed by software quite easily.

For normal situationsI go up to ISO400 w/o worrying. But always remember, a noisy image is way better than a blurry one!
