The only downside to all this brilliant analysis is the mountain of data, which is really
quite difficult for non-mathematicians to interpret. Fortunately, there is a solution. The
people at SLRGear.com turn the data into 3D graphs that give, for example, unique
insights into lens performance at various focal lengths and apertures. DxO Analyzer is
a tool for professional use in the testing lab, although a number of hobbyists are sufficiently
obsessive about performance issues to find it a source of endless entertainment.

HotPixelRemover
Chapter 37 ■ Analysis and Diagnostics Software 427
Vendor: Lightning Cube Software
Purpose: Eliminates problematic “hot pixels” from dark areas of the image
Description
HotPixelRemover uses the “dark frame technique” to detect and remove hot pixels from
your images. Hot pixels are the unwanted bright dots that show up in dark or shaded
areas; the dark frame (or “black frame”) technique traditionally uses an exposure taken
with the lens cap on, keeping the shutter open for the same length of time. The software
subtracts the black image from the actual image so that the hot pixels, which are
the same in each exposure, cancel each other out.
With the HotPixelRemover software, you take a series of dark frames to cater for
different image capture settings and then load them into the program. Removal of hot
pixels then becomes an automatic process.
HotPixelRemover image analysis tools allow you to see how badly your camera is
afflicted by hot pixels. There is usually an increase in their number as a camera ages.
The software allows you to keep track of your camera’s performance in this respect over
time. You can save analysis results in XML and HTML formats.
Comments
HotPixelRemover is very effective at taking out hot pixels from images of various sizes.
It looks at many parameters, including camera make and model, image size, color or
monochrome, ISO value, digital zoom value, exposure time, focal length value, and the
