This video compares 8-bit and 16-bit images
- [Instructor] In this movie I'll explain the difference…between 8-bit and 16-bit images.…Most images we work with are 8-bit.…That is there are eight bits of information…to describe every pixel.…Two to the power of eight, hence the 256 brightness levels…in an RGB image.…For most images, this is enough.…16-bit images contain twice as much data.…The most common type of 16-bit image…is a camera raw file,…and both the Camera Raw plugin and Adobe Lightroom…let you edit and output 16-bit images.…
Here I have the same image as an 8-bit…and 16-bit version.…On screen they're not going to look any different.…If we look at the document sizes,…we see that the 16-bit is literally twice the size…of the 8-bit version.…What we gain with the 16-bit version…is the ability to tease out more information from the image.…Because there's more data to work with,…we can make more changes to the levels or curves…before a histogram starts showing the telltale signs…of degradation, a combed effect,…indicating that at certain brightness levels,…
