Camera Noise Go Away!
I hate camera noise. While it’s not a problem with small, low resolution photos shared on the web, it can be a big problem when you enlarge the photo and print it out.
What is noise? It’s those color speckles (that looks like grains of sand) that show up in skies or light spots in your photos.
A sample of what camera noise looks like
What causes noise? Noise is caused when the image is recorded on the sensor of a digital camera.
There are several causes for noise, including what type of camera (sensor) you have. Generally, the higher end Digital SLR cameras produce less noise because they use the higher quality and larger sensors.
While a number of factors that cause noise are within the photographers control, others not.
For instance heat generated ‘free electrons’ from the sensor itself can cause noise. And, again the type of digital camera you have.
Ways to control noise is my mission these days – especially after the weekend shot that created a bunch of useless photos!
Over the next few posts I’m going cover a few techniques I’ve learned for controlling noise.
This is important for a couple of reasons – one is simply to get the sharpest, best looking enlargement for you favorite subject. Another reason to control noise is producing high quality images that I can submit to iStock or shutterstock or sell at one of the other microstock agencies.
Tomorrow I’ll cover a few simple techniques to keep noise at a minimum
