White Light : "Colour my Mind"

"White light" is anything but white...
"White light" is simply the term used to name all the colours we see like a rainbow.
It is the total spectrum from blue through green to red light that the human eye can see, and that film and digital sensors are designed to "see" or record.

I love doing this kind of creative photography where I use coloured filters to highlight and accentuate or totally block a certain colour, with multiple exposures using different colour filters...

"Infrared Light" is beyond our visial ability detect, but not to specially sensitive film or sensors.

It is slightly different in that, as well as being reflected along with the normal red light, it is also transmitted, but only by living things, and when in Black and White mode that light shows up as bright white.
Non living things do not transmit any infrared light so they appear darker and only reflect the normal light.
In colour mode, but with a fully opaque filter to allow only the infrared light through it is possible to get some unreal looking images that are just red and black.

I cross process colour slide film using colour negative processes which shifts the light.
It does not change, for example, red light to blue light, but it shifts it slightly and creates some wacky images with some vivid and intense colours.
