Obviously this isn't ALL infrared but I wanted it here anyway. I took a colour and IR photo and combined them in Photoshop CS3, added a gradient to get the effect you see here.
IR photo: 2 seconds at F5.6, 800 iso, Hoya R72 IR filter
Colour: 1/2500 at F10, 800 iso
Both Photos: Sony A100, 18-70mm Sony kit lens, tripod.
