What were the results, were you happy with them? What brand of film did you use? I can find Iford or Rollei but should I look around for something else? (I know nothing about infrared film.) Also, is the red holga filter good for this or would you recommend a better one? Would love to see some examples if anyone has some to share.
There's an article at holgasonline.com about infrared: http://www.holgasonline.com/holga-techniques-infrared.html They also have some photo samples up too.
