Question

What is the color depth of RGB images (no alpha channel)?

Answer 1

In RGB pictures - 8-digit "mode" signifies three 8-cycle channels of RGB information, additionally called 24-bit "shading profundity" information. This is three 8-bit channels, one byte for every one of the R or G or B parts, which is 3 bytes for each pixel, 24 cycle tone, and up to 16.7 million potential shading mixes (256 x 256 x 256). Our screens or printers are 8-bit gadgets, which means 24-digit tone. 24-pieces is awesome for photographs.

Alpha channels are veils through which you can show pictures. The alpha channel is a 8-cycle channel, which implies it has 256 degrees of dim from 0 (dark) to 255 (white). White goes about as the noticeable zone; dark goes about as the straightforward zone (you see the foundation behind the picture when shown). The degree of dim in the middle of decides the degree of perceivability. For instance, 50% dim takes into consideration 50% perceivability. Alpha channels are generally utilized with 16.8M shading RGB pictures. The subsequent picture is called RGBA (RGB+A, A methods alpha channel).
