I had a selection of things I could have done for my art history class, and I chose to take a picture of something and create an infrared image(the easiest). Well I have been messing around with random online image editors and some free apps and I can't seem to get it to work. I can't even find something simple that has a "infrared" option, like there is for sepia and such.

Can anyone help ? I don't have photoshop btw. Oh yeah, and its due in a few hours.
