What's that... eh... thing, in Capture NX?

The documentation of Capture NX is not perfect and the usability of the product is far from perfect. Here are a few things I have not found in the documentation.

Sometimes you see a yellow warning triangle in the window title bar.

This triangle stays as long as the the text "updating image" stays in the title bar, so it probably means the same thing. In other words, it does not mean the file is corrupted or contains bad data or too much highlight or that anything else is wrong. It simply means "wait".


When you display the white balance settings for a file in Base Adjustments > RAW Adjustments > White Balance, you may see numbers and letters after the Camera WB. It may be something like "Auto, A3, G2" or "Incandescent, 0,0" or "6000K, A2, G3".

The first information is the white balance type or the colour temperature expressed in Kelvin. The following two numbers are the adjustments you may have done in your D300, under Shooting Menu > White Balance > right arrow.

The first adjustment is the value on the Amber (A) - Blue (B) axis, and the second one is the value on the Green (G) - Magenta (M) axis. Coincidentally, this corresponds to the LAB colour model. The amber-blue axis confusingly corresponds to colour temperature as well, with each step equivalent to about 5 mired. The green-magenta axis is simply an adjustment of green-magenta, like a cc filter (colour compensation/colour correction filter).
