others can be more technical, but in using the camera, I had one episode,
where I set up a girl in a black tee shirt in dim light and photographed
her under tungsten light using a noctilux. The shirt was translated by the
camera as being quite purple. Software 'fiddles' cured the colour, but
perhaps at the expense of any real purple in the colour palate of the
image. The purple is due to the infra red sensitivity of the M8. It thinks
there is purple light coming from the black fabric under these
circumstances.

There "must" be an IR effect at other times, but it is much less obvious,
when the visible light is "dominant". I have noticed that the hue of my
beach images might be a bit warm, and I hope to post these soon. I do not
know if this "warmth" is the magenta tint or not, but when I get an IR
filter that would solve it BUT when you process the RAW image the colour
balance looks very good in even these images.

Cheers
