This effect was generated in Filter Forge, a Photoshop plugin that allows you to create your own filters.
This filter applies a FLIR (thermal imaging) effect to photos, pictures and textures. Its very useful in reproducing military and police thermal images from any image you want. White hot and black hot are interchangeable in this filter.
The controls are there for fine tuning, the two presets are generally all thats needed, though blur can be taken off for a much sharper image.
Have fun and enjoy this filter!
