In Photoshop CS3 there is a new feature, Image > Adjustments > Black and White. In the dialog there are several presets you can choose from, one is Infrared. I’ve always admired, Dave’s infrared photography, which he does with an attachment for his camera. I haven’t broken down yet and gotten an attachment.
This experiment though has made me really want to get one though. I did a little tweaking of this photo after the basic infrared was applied. I created a slight vignetting, along with some edge blur. I’m happy with the final product.
Here is the original image.
