what does bits/channel mean

[Aapti]

Hello , I Have a Small question on coding of images , I Have some images that now i want to know what does Bits/channel Mean , Can You tell is this related to Quality of images , please help me Thanks in advance

In 8-bit, you can quickly get combinations that degrade the image somewhat, especially when using masks with gradients as I often do, of course it is often our fault as a poor choice in the order of layers or other ... but in 16-bit, it is rare there are less limitations other than the source itself or in Short, work in 16-bit is more flexible.

RGB is a color combination, which is always 255 degrees per Color. The 8 or 16 bit setting is in PhotoShop on the other hand, it influences the "resolution" of the colors. The picture will contain more Information - but not more colors will be available. 16-bit files are twice as large as 8-bit files and can store up to 256 times as much information.

There are 8-bit or 16 bit files. These are indications for a color or monochrome images , 1 bit is the smallest unit of information of the computer world. There can be two states such as On or Off, O or 1, black or white. Let's keep at zero and one. Eight bits can consist of eight zeros: 00000000th Or from eight ones: 11111111th ,In addition, your imagecan be of any combination of zeros and ones in 8-bit packing. For example, 00011100 or 11,001,100th With eight bits there can be 256 different combinations of 00000000 through 00000001 and 00000010 to 11111111

• 1 bit = Black / White
• 4 bit = 16 colors or 16 shades of gray
• 8 bit g=rayscale or indexed colors (256 gradations)
• 16 bits = 65,536 colors
• 24 bit = 16,777,216 colors - True Color mode for playing Photos on your monitor (RGB)
• 32 bit = 16.7 million colors, plus 8-bit grayscale mask (alpha Channel)

In Grayscale encoding the pixels of the image are represented by several gray levels: the lowest being 0 which corresponds to the color black and the largest value being [depth ^ 2] -1 (depth to the two least one power ) Which represents the color white as you can see the total number of gray levels is a function of the depth of the image:

8-bit pixel-coded 8-bit Grayscale mode allows 256 shades of gray. The value of brightness of each pixel of an image in greyscale ranges from 0 (black) and 255 (white).
16 bits: 2 *16 = 65,536 grayscale (black = 0, white = 65535)
