Red-Eye Correction

This creates new versions of images attempting to rectify flash-induced red eyes. This filter is sneaky enough to know if you used flash or not to make the image, and won't let you use this filter if you didn't use flash.

I've never had a problem with red-eye with my D40, so all the better. When I was able to cause red-eye, this filter only corrected half of the eyes!

Trim

This creates new cropped versions of images. No pixels are moved or changed in size. Trim removes unwanted pixels from the sides of an image and saves a smaller image.

Monochrome

This creates new black-and-white versions of images.

It has three modes:

Black-and-White,

Sepia (Brown-and-white) and

Cyanotype (Blue-and-White).

Filter Effects

This creates new versions of images with different colors. You've got your choice of:

Skylight: slightly warmer and pinker.

Warm Filter: slightly warmer.

Color Balance: This one's slick. It calls up a better control panel than Photoshop's color balance tool, which dates from the 1980s.

Nikon's tool reminds me of what we have on million-dollar color correction machines used in Hollywood telecine to color correct motion pictures.

The Nikon D40 shows three histograms (reminiscent of Tektronix' WFM700 waveform monitors) and the D40's Up/Down/Left/Right key becomes the color correction track ball. Click it left and right to alter blue-red, and up down for magenta - green.

If you have something neutral, watch the waveforms, oops, histograms, until they are about equal. Left - right on the Up/Down/Left/Right key slides the red and blue in opposite directions, and green
