Free Photoshop plugin
Reindeer Graphics has released a new free plug-in, , for Photoshop 5.x, 6, 7, and CS on Mac OS 9/X: "[It] is a tool for exploring the detail in the histogram of a 16-bit image that cannot be shown in Photoshop. The plug-in can display the histogram in three widths that give between 2x and 4x the resolution of the histogram palette in Photoshop. The plug-in provides eight different modes for the histogram display, including RGB, red channel, green channel, blue channel, 'colors', hue, saturation, and luminance." Wide Histogram is a free component of Optipix, a $150 suite of Photoshop-compatible plug-ins for correcting common problems in digital images.
