Noise Reduction Update

A few posts back I mentioned a new noise reduction program I had been using with my GX1 images. The program was Topaz DeNoise and I had a 30 day free trial. Well I’m happy to give an update and I will start by saying I purchased the full edition.

After the blog I got down to the serious business of trying out quite a few noise reduction products. These ranged from OK to quite good but DeNoise was the best for my needs. I must admit that if I was judging this purely on how effectively some of the products removed noise, there were a couple of programs that seemed to match the performance. Unfortunately these were devilishly complicated to use.

The problem most of the programs seemed to suffer is that they had too many tabs and sliders to be adjusted. First I would need to select the range of noise e.g. high frequency, medium frequency etc then I would select the level of reduction for both luminance and colour noise. In addition to this I could target tones (highlights, mid tone and shadows) as well as different colours. Often there were a number of other controls I also needed to play with. These solutions to me are not lightweight and usually left me wondering if I had made the best selection I could. I also wasted a lot of time cycling through all the options trying to perfect the noise reduction.

What I really like about DeNoise is that it’s very quick to use as well as being very effective. Firstly I set the level of noise reduction whilst viewing a mid-tone area of the image. I then look at a shadow area and use a shadow slider to increase or decrease the level of noise reduction in these areas. Next I check the highlights and use the highlights slider to make any further adjustment.

Once I am happy with the noise in these areas I can apply additional colour cleaning noise with another slider as well as using two more adjustment sliders to affect the red or blue channel. What’s great about these sliders is that they all work together. The first slider is enough to achieve good results but the other sliders allow you to fine tune and target the effect.

Once you have applied your noise reduction you might find you have impacted some of the very fine detail. To counter this there is a “Recover Detail” slider which is quite effective. There is also a De-Blur slider which I never fail to be impressed by. This is something that I first came across in the Topaz Detail plug-in and it reduces typical lens blur introduced by camera optics and anti-alias filter. Even with top quality optics and perfect technique, this slider can make a difference. There are a few other sliders to help you really get superb results but this blog was not intended as a product review.

This is a very impressive package that it incredibly easy to use and achieve superb results. Even shooting at the best ISO possible with my cameras, this plug-in will improve the results. Give it a try if you want a lightweight noise reduction workflow that is totally effective.
