Tech Tips - What is Noise In Digital Photography And How to Reduce Noise In Photos!

Hey guys Brainy Here and welcome to another
Tech Tips Video. In todays video, lets talk a bit about
cameras and more specifically, lets talk about what the term noise refers to when using
a camera. So lets get right into it. In digital photographs, noise is the
commonly-used term to describe visual distortion.

It looks similar to grain found in film photographs,
but can also look like splotches of discoloration when its really bad, and can ruin a photograph. Also, Noise tends get worse when youre
shooting in low light. In low light, there is not enough light for
a proper exposure and the longer we allow the image sensor to collect the weak signal,
the more background electrical noise it also collects. In this case the background electrical noise
may be higher than the signal.

From a technical point of view, noise is the
visual manifestation of a lower signal-to-noise ratio, which is measured in decibels. While the amount of noise that you may consider
acceptable may be different from what the someone else may accept, most professional
photographers want to see photos with at least a 30dB signal-to-noise ratio. In many cases, one camera may produce more
noise than another camera. Digital cameras convert light into electricity
and then that electricity is converted into pixels.

Each camera manufacturer uses different sensor
chips and software to handle these conversions. As such, some cameras are better at reducing
noise than others. In addition to software, the size of the sensor
itself and the number of pixels on that sensor can affect the amount of noise and how big
the flecks are when noise does occur. So, now that we kinda have a basic understanding
of what noise is, how can we reduce the amount of noise in our photos?? Well, you can Shoot at a low ISO, Get a camera
with a larger sensor, Use your cameras on-board noise-reduction or Use noise-reduction
software on your computer.

Now those are just a few methods you can use
but the main goal here is that you use what works best for you to reduce the level of
noise in your photos. And yeah, thats about if for this quick
