IR photography

Bhaiya's H50 has an inbuilt 'Night Mode' that uses a short beam of Infra red light to shoot pictures in complete darkness. I gave it a try on myself and the results are very interesting. Note the dilated pupils due to the pitchblack darkness. Reminds me of a recent movie :-)
The IR light however is of  very limited range and hence suited for a distance of upto 2 metres at best.
