  6. Nice job, very well explained and simple. Reading the comments I think people need to understand that slight variances in filters (Not all 720NM Filters work alike) and the variances in the cameras hot filter (If not converted) will allow different ratios of visible light to get exposed and give a result different than you’ve accomplished. This tutorial should allow someone new to IR to get the best looking image with the camera/filter combination they are using.

    I took some pictures with a Canon 50D 70-200mm f5.6 15s Optek R72 filter.
    The pictures came out red and blue channels when I changed the picture went red by red.
    Can anyone help me?
