Noise, reducing it as
January 24, 2011
User archive
One of the biggest problems that a photographer faces, is surely one of the "noise". Its effect is especially noticeable when using high ISO (up to about 400) and occurs mainly in the darker areas. In fact, in low light situations, the individual pixels that make up the sensor in our camera, they perceive the photons in slightly different ways, and this causes the so-called noise.
The best ways to reduce it?
First, try to use (whenever possible), ISO below 400. Minimize exposure time and, if you can, if they limited the dark areas contrast with some lighter ones.
It is clear that the noise is also linked to the camera we use. Professional machines are able to minimize this effect, unlike the cheaper (so-called entry level), which require more attention from the user.
These little tips are given from my own experience. And 'welcome anyone who wants to contribute to this discussion.

Thanks for the advice and suggestions. Unfortunately, the basic functions of
photoshop, there is a good tool to reduce noise. It is therefore necessary
resort to external programs.

I've just started using a program called 'Helicon Filter' (I downloaded a free version - just do an Internet search) & have been quite pleased with the results so far. It's really easy (for a slightly clueless person like me!) to use & also has other features such as sharpening etc.

My D90..ISO always at 100...if needed ISO 200!!!!

I used to think I had to buy a whole new gear but I realised as I learned that quite a few things can be improved with technique...

I use a Nikon D90, with a D50 as backup.
At ISO200 the D90 has very little noise, and is much better than the D50.
At ISO400 the D50 shows about the same noise as at ISO200, and shows less noise than the D90.
At ISO800 the cameras are more or less the same.
At ISO higher than 800, the D90 is better.
I actually have photos on DT taken with the D50 using ISO800.

Agree on this.
Noise is a photographer's nightmare.

I have a D50. With my zoom 18-200 the noise is really bad at 400 ISO but with my 105 lens it can actually be acceptable sometimes. I also think that some higher end cameras like the D90 or the D300 handle the light much better.

You are right...I have a D60 and it make that ugly noise when I put the iso between 200 and 1600 . Only on iso 100 the photo is out of noise. But when the light is low....this is a very big disadvantage...
