Image Quality

• Sensor Size (Medium Format vs Full Frame vs Crop)

• Resolution: Pixel count (24MP vs 42MP)

• Resolution: Pixel density (PPI or DPI)

• Pixel Bit depth: 8-bit (2^8 or 256 tones), 16-bit (2^16 tones)

• For An 8-bit sensor, each pixel may be any 1 color (or tone) from a range of 256 tones per R/G/B channel

• That is to say each pixel may be any tone from 256 x 256 x 256 possibilities or 16 Million possibilities!
