Description

This includes Nikon's seven variations of flourescent (the default is the fourth, 'Cool WHT FL').

{ "NIKON", "D7100", "Incandescent", 0,        { 1.445313, 1, 2.667969, 0 } },
{ "NIKON", "D7100", "Sodium Lamp", 0,         { 1.332031, 1, 2.894531, 0 } },
{ "NIKON", "D7100", "Warm WHT FL", 0,         { 1.480469, 1, 2.425781, 0 } },
{ "NIKON", "D7100", "White FL", 0,            { 1.746094, 1, 2.777344, 0 } },
{ "NIKON", "D7100", "Cool WHT FL", 0,         { 2.222656, 1, 2.417969, 0 } },
{ "NIKON", "D7100", "Day White FL", 0,        { 2.242188, 1, 1.65625, 0 } },
{ "NIKON", "D7100", "Daylight FL", 0,         { 2.628906, 1, 1.308594, 0 } },
{ "NIKON", "D7100", "Mercury Lamp", 0,        { 3.1875, 1, 1.585938, 0 } },
{ "NIKON", "D7100", "Direct sunlight", 0,     { 2.386719, 1, 1.597656, 0 } },
{ "NIKON", "D7100", "Flash", 0,               { 2.753906, 1, 1.371094, 0 } },
{ "NIKON", "D7100", "Cloudy", 0,              { 2.65625, 1, 1.453125, 0 } },
{ "NIKON", "D7100", "Shade", 0,               { 3.183594, 1, 1.292969, 0 } },

All of these are the unmodified version of each preset (with no tuning applied). Nikon claims that fine tuning a preset through the command dial is roughly equivalent to +/- 5 mired for each step (and they go to +/-6 steps).

According to Nikon's D7100 manual, the approximate Kelvin values for all of these are 3000K (incadescent), the fluorescents at 2700K, 3000K, 3700K, 4200K, 5000K, 6500K, and 7200K, then 5200K (sunlight), 5400K (flash), 6000K (cloudy), and 8000K (shade).

Sorry, for missing this for so long.

We already had some D7100 preset committed but not the complete list apparently.

So I just committed your list:
