What's infrared photography and what's a infrared lens?

Answer 1

Infra red photography is basically taking pictures in the infrared spectrum rather then the regular visible light we are familiar with. I haven't come across an infrared lens but infrared film is fairly common. The notable exception to that would be the Sonay camcorder that could do 0-lux video (which they eventually limited because it could somewhat see through clothes if used in daylight).

You can also do infrared photography with some digital cameras, I've attached a link which walks you through on how to achieve that.

Answer 2

Infrared photography is taking pictures with the spectrum of light that's between what's visible and the microwaves used for radar and microwave ovens. It basically uses the heat generated by all objects. Hot stoves, pavement, and cars will show up quite bright, as will green trees and shrubs, and people will show up brighter than the cooler background.

You can get infrared digital cameras, but they're quite a bit more specialized than the usual mass market digital cameras. Another name for them is "night vision" equipment.

An infrared lens is optimized for infrared light. A lot of manual focus film cameras have a red dot marked on the focusing scale on the lens. It's so you can refocus the lens if you're using in fared film, since most lenses focus infrared differently than visible light.

Answer 3

Infrared is in the light spectrum the is invisible to the human eye. To do infrared photography you will need special film, available at most good camera shops. Also try E-Bay.

Answer 4

Infrared focus's on heat eminating from an object. Even though something may be invisible in the visible light spectrum, if there are differences in temperature, infrared will pick up the differences and make them visible.

I hope this helps.
