Recently have been eager to try my hand at infrared film photography. I've only done black and white film and color film so far, and have had experience in altering my negatives in post for interesting effects.

The specific type that I am looking to try is color infrared film, which I am guessing is used in work similar to Neil Krug's work: https://www.google.com/search?q=neil+krug&espv=2&biw=1745&bih=883&source=lnms&tbm=isch&sa=X&ved=0CAYQ_AUoAWoVChMI6MfelObUxwIVgiaICh0VHQak

However, being a newcomer to infrared film, I am not 100% if that is the reason for the saturated and vintage look we're seeing here. What is done to get this very effect?

Also, about the filter used in infrared film, is it a red filter or yellow? I've read online people are using both, but what type of filter is needed for it?

Any input helps, thanks a lot!
