Dropper Sample Size - Nikon CAPTURE NX2 User Manual

Dropper Sample Size

Use this option to set the sample size of the droppers used within the "Color Picker", "Levels & Curves", and
"Watch Point" elements of Capture NX 2. When Point Sample is selected, a single pixel will be sampled
when a dropper is used. With the 3 x 3 Average and 5 x 5 Average options, the average of the pixels
sampled will be used. Choosing a large sample size reduces precision, but also minimizes the effects of
noise; choosing a small sample size has the opposite effect.
