Bit depth and data
JPEG images store eight bits of data, but NEF files capture much more
8-bit JPEGs store 256 shades per channel.
01 That’s fine, until you start wanting to heavily manipulate your images.
12-bit NEFs capture 4096 shades per 02 channel. This gives much smoother tones.
14-bit NEFs capture 16,384 shades per 03 channel, but you often won’t be able to see any difference next to 12-bit NEFs.
