The 4-bit per pixel (4bpp) format supports 16 distinct colors and stores 2 pixels per 1 byte, the left-most pixel being in the more significant nibble. [5] Each pixel value is a 4-bit index into a table of up to 16 colors. The 8-bit per pixel (8bpp) format supports 256 distinct colors and stores 1 pixel per 1 byte.
Like any resampling operation, changing image size and bit depth are lossy in all cases of downsampling, such as 30-bit to 24-bit or 24-bit to 8-bit palette-based images.. While increasing bit depth is usually lossless, increasing image size can introduce aliasing or other undesired artifa
Depending on the color depth, a pixel in the picture will occupy at least n/8 bytes, where n is the bit depth. For an uncompressed, packed-within-rows bitmap, such as is stored in Microsoft DIB or BMP file format, or in uncompressed TIFF format, a lower bound on storage size for a n-bit-per-pixel (2 n colors) bitmap, in bytes, can be calculated as:
The HDMI 1.3 specification defines a bit depth of 30 bits (as well as 36 and 48 bit depths). [21] In that regard, the Nvidia Quadro graphics cards manufactured after 2006 support 30-bit deep color [22] and Pascal or later GeForce and Titan cards when paired with the Studio Driver [23] as do some models of the Radeon HD 5900 series such as the ...
The lower colour depth versions of PNG store colours in a palette. Paletted images can have a bit depth of 1, 2, 4, or 8 bit (2, 4, 16, or 256 colour). Use the lowest bit depth that can handle all colours in your image, although some image editing programs cannot create 2-bit colour images.

This means how it would like to appear in daylight at 12pm, or under standard office light. Too bright images can disappear completely on some monitors. Generally different monitors can cause a change of 50 percent, there is never "exact" reproduction. In case of doubt, test the image file on different computers. Select the Image menu.
Bit depth may refer to: Color depth, also known as bit depth, the number of bits used to indicate the color of a single pixel; Audio bit depth, the number of bits of ...
