Smart Noise Reduction Filter
|Top Previous Next|
It's a fact that all digital images contain noise even at low ISO settings. Often this noise can be seen in the details in shadows and in blue skies. As the ISO sensitivity is increased this noise becomes more and more pronounced to the extent that the highest ISO settings for most digital cameras are barely usable. With BreezeBrowser Pro's Smart Noise Reduction technology, SmNR for short, you can now do something about it. SmNR filters out the noise in images and, unlike other noise filters, there is virtually no loss of detail.
To get an idea of what SmNR can do, take a look at the speedway shot below taken with a Canon EOS-1D at ISO 1000.
The two pictures below show the effects of SmNR on part of this image. Both images are unsharpened and were converted using identical settings in BreezeBrowser Pro - the one on the left has SmNR turned OFF and the one on the right has it set to High.
Notice how the noise in the area behind the rider and on his goggles has been filtered out in the right shot with virtually no loss of detail.
SmNR has been carefully designed and optimized using a large number of images from different digital cameras. Unlike other methods, it is optimized for each camera model. Because noise from different camera models is actually quite different SmNR uses shooting data from the image to determine the best settings to use. It then carefully analyzes your image and decides which areas contain important details and which contain undesirable noise, removing the noise and leaving the details untouched.
SmNR can dramatically reduce the noise in shadow areas and this effectively increases the usable dynamic range of the image. So techniques like Contrast Masking are more effective and more detail can be rescued from underexposed images.
BreezeBrowser Pro uses noise reduction technology developed by Kevin Dobson. Click here for more information.
