I first made these kinds of images on a whim, but now I look for compositions that will work well as a mirror image. Internal 665nm infrared filter on all.
Can you explain in more detail the method or is it all post processing/computer manipulation?
Is the center image taken with an IR camera or filter? I am not familiar with your initial statement "Internal 665nm infrared filter". I am thinking about trying out IR photography and would be interested in getting your opinions if this is what you are using.
