Camera Adjustments

❏Non-Picture Control Based Adjustments

When images taken with D1-series, D2-series, D100, D200, D80, D70S, D70, D60, D50, D40, or D40X cameras are edited with the Non-Picture Control option selected in the Camera settings step in the “Develop” section of the Edit List palette, the sharpening, tone compensation, color mode, and

saturation settings in effect at the time the photograph was taken are marked with an asterisk (no asterisk will be displayed if “Auto” was selected for sharpening, tone compensation or saturation). Choose Unchanged for results identical to those obtained with the camera; other settings may not produce the same results.

❏ “Mired”
Any given change in color temperature produces a
	Change in Color Temp.	Mired
greater difference in color at low color temperatures than
	4000 K – 3000 K = 1000 K	83 mired
it would at higher color temperatures. For example, at a
color temperature of 6000 K, a change of 1000 K	7000 K – 6000 K = 1000 K	24 mired
produces almost no change in color, while a change of

the same amount at 3000 K would produce a large difference in color. Mired, calculated by multiplying the inverse of the color temperature by 106, is a measure of color temperature that takes such variation into account, and as such is the unit used in color-temperature compensation filters.

❏Gain

The values for red and blue gain chosen in the “White Balance” section are multiples of the value set for gain when the photograph was taken.

❏Choosing a Value for Gain

Very large and small values for gain can result in a drop in image quality.
