Testing Infrared Software

This post is to show one of the features of WavelengthPro, some photography software I’m writing at the moment. It’s in early stages at the moment, I hope to add a lot more.

Channel Map Templates
I plan on having a basic and advanced way of mixing channels, so far I’ve done the basic version where you choose template maps. The advanced version will use percent sliders of every channel for every channel just like in Photoshop or GIMP etc. Below is a table showing the three starting images (all taken on a full-spec D70 using 720nm, Hoya UV/IR cut and Baader-U filters) and some of the possible mixtures using the program.

Random Idea

Ok this really is an idea that’s fresh in my head, i couldn’t sleep and this
started swimming around..

Multi-Spectrum Imaging: Quantitively assigning the entire EM
spectrum to a corrasponding RGB value and building some sort of multifunctioning
camera that can capture all the different types of shots then transform them
into this image.
An added thought was to assign shades of gray to the entire
sonic spectrum then apply this ‘shader’ to the same image..

Different Imaging techniques in use

Purely experimental, but if it could be done would demonstrate ways of
visualising multiple areas of electromagnetism at the same time.
