Infrared LEDs for lighting

Post by geaplanet » 04 Dec 2015, 06:04

Taking into account that IR leds are cheap, I was wondering if infrared light could increase definition or sharpness in the images capturated by cameras (together with the normal light). Someone has tryed something related with this?

in "better" (or all) cameras there is a IR blocking filter in front of the sensor.
The camera is constructed to make a image of what we see and therefor the manufakture of the camera has block the IR.

I have not try to see what resolution I can get with IR light and I don´t think I will do that.
I do not have a IR light right now.

UV light is no good for this

Additional, IR LED would be unsuitable for taking pictures of anything with 'colors'.
