Shooting in RAW format to reduce noise


posted on 28th of may, 2008
I've recently came back from a volunteering mission in Morocco. I needed to pack light so didn't bring my full camera gear and didn't bring my flash. Now not having a flash means that many of the indoor lighting conditions I had to shoot at high ISO which normally translates to more image noise. However, I'm going to share a technique I've learned from another camera forum in the past which goes over how to reduce noise in low lighting shooting at high ISO which I think you'll find useful.

First of all you need to shoot in RAW for this technique to work. First of all lets define what noise is and this way you will understand the technique I'm going to explain easier. Noise occurs in the region of low signal of your camera sensor or image. i.e. occurs where things are dark....

Arindom, you are totally correct. So you definitely need to watch your histogram. However, at higher ISOs the dynamic range of the sensor is much greater than lower ISOs. Therefore more of the highlights will be preserved as long as your histogram is not over the right limit of the graph.
