Tried a few more shots through the floppy slot.  top pic is right out of the camera, middle is with just auto levels applied, bottom is the red/blue channel mixer swap.  This first post is auto white balance.  Note my camera is a Fuji with the IR hot mirror removed.  I did notice that the exposure times are longer through the floppy than through an R72 IR filter.  I was also in the spot meter mode.
