Learn about the different types of noise that can occur in digital images and find out how to prevent and fix them.
Image noise in photography can be frustrating, but it’s often just a natural outcome of capturing light digitally. Several factors can contribute to its presence in your photos. 1. High ISO Settings ISO is a setting on your camera that affects how sensitive the camera sensor is to light. ...
ISO is one of three factors which determine the exposure of a photo, along with aperture and shutter speed. To really get the most out of your photos you need to know what all 3 do and how you can use them. Read this post to gain a more in depth knowledg
We’ll break these down in a bit, but first let’s list some things that aren’t important to a photo’s success. These are in no particular order and constitute what I call The Box of Technical BS. Behold the contents of The Box: megapixels, noise, corner performance, RAW headroom,...
While graininess is sometimes used as an artistic effect in photography, lower ISO values will give you less noise or grain on your final image, which is typically ideal. “You want your ISO to be as low as possible while still freezing the action, even if you want some grain for stylist...
Pixel binning, also known as pixel merging or pixel combining, is a technique used in digital imaging sensors to improve low-light performance and reduce image noise. It involves combining the signals from multiple adjacent pixels into a single larger "superpixel." By merging the pixel data, the...
Final Thoughts Image aliasing is a pervasive issue in digital imaging caused by under-sampling or inappropriate handling of high-frequency image details. While eliminating aliasing might not always be feasible, you can significantly reduce its impact by understanding the core concepts and mitigation tech...
This mechanical process is so fast that when you are photographing using a fast shutter speed it is not noticed by the camera. But in low light photography, this process can cause a small vibration. This movement can make your image look blurred. This is a common rookie mistake when ...
What is ISO in Digital Photography? When we talk about digital cameras, ISO measures thesensitivity of the image sensorwhich sits inside your camera. The lower the ISO number, thelesssensitive your camera is to light. It also means there will be less noise (or ‘grain’ if you’re using...
image, use a wide aperture (low f-stop number) to create a shallow depth of field and blur the background. This is the most popular option in portrait photography. With a lot of light entering the lens you can set a faster shutter speed, which is an advantage in candid photography. ...
