Dave McDonell on Noise

September 30, 2009 | Leave a Comment |


Dave McDonell, cofounder of Imagenomic, the company that makes Noiseware, my favorite noise reduction software weighs in on noise.

JPC    Where does noise come from?

DM    There are several factors in a digital camera capture process that contribute to noise. The most prevelant are temperature, the actual capture circuitry, sensor size, and the process of sub-sampling which induces errors between adjacent pixels.

JPC    Why is chrominance noise so much easier to reduce than luminance noise?

DM    It’s really not in application. It’s just that you perceive changes in luminosity or brightness much easier than you do in color.

JPC    Fine color noise is easier to reduce than coarse color noise, like the color patterns created by demosaicing bayer patterns. When are you most likely to encounter this type of noise? How should you treat it differently? How far can you go?

DM    There are no hard and fast rules for any of the above questions as all are dependent on the capture situation and subsequent output medium.

JPC    What’s the biggest challenge when reducing luminance noise?

DM    Achieving a balance between perceived reduction and image detail.

JPC    At what point would you stop using the sharpening controls in Noiseware Pro and start using the sharpening controls in Photoshop?

DM    Again, another matter of workflow organics. Each person has a specified workflow as to input, editing and output.

JPC    Do you recommend reducing noise before or after sharpening? Why?

DM    In the vast majority of cases, use noise reduction before sharpening as sharpening will almost always magnify existing noise patterns.

JPC    Do you recommend reducing noise before or after upsampling? Why?

DM    Along the same lines as sharpening, any noise patterns will be magnified. Sometimes it is necessary when resizing to use noise reduction in 2 steps – one on the unsized image and another finishing reduction on the upsampled image.

JPC    Tell me about one or more features of Noiseware Pro that typically get overlooked and under used.

DM    Probably the most under used but most powerful feature is the bracketing function. One can quickly establish usable ranges from which presets can be generated. Presets is another overlooked feature whereby one can establish customized slider settings for a wide range of images.

JPC    Is all noise bad?

DM    All images have noise to a degree, regardless of capture method.  When the amount and/or type of noise becomes such that it is viewed as degrading to the image, then we definitely toss it in the bad category.

JPC on

Recently Rayhaan Traboulay interviewed me for his online magazine thirdeyephotozine. Here’s an excerpt.

RH I recently had a discussion with a friend about creativity within people. I
find that people either generally “have it” or don’t. I believe that you
can’t really teach it too much. Theres room for improvement and critiques
and so on, but I find it is either innate in someone or it’s not. Would you
agree or no?

JPC I disagree – strongly. To be a successful creative person in any field, it
takes perseverance, intelligence, hard work, skill, talent, and luck – in
that order. Everyone is creative. Different people have different creative
strengths. It helps to find the areas each of us are strongest in and to
develop skills within other areas to become more versatile. Creativity is
not contained to the arts. Some of the most creative people in history and
with us on the planet today work in the fields of science and business. We
all have something to offer. And something to learn from each other.

Do you think you can learn to be more creative? Comment here!
