Digital Leica M8 / M8.2 / M9 / M-E /Mono / M10 aka "M" Discussions about the Leica M8 /M 8.2 / M9 / M9-P/ M-E / M Monochrom / M10 aka "M": Leica digital M mount rangefinder cameras. Naming the new digital M the "Leica M" is VERY unfortunate as it will only confuse newbies with other Leica M cameras of the the past. Happily there is room for confusion with only the past 59 years of Leica M production ... since Leica introduced the Leica M system in 1953. All Hail for the Leica Marketing Department learning Leica M history!

The IR cut filters that work by interference, like B+W #486, cause the corners of the frame to have a cyan cast. This only happens with lenses with wider picture angle than 35mm for full frame cameras (if I remember correctly). Jorge's 15mm picture in this thread is an example:

Make a circular gradiant in ps complimentary to the shift. Try red to start. Move the sliders around so it starts where the cyan comes in.

Now apply in the center of the frame and it will cancel the cyan depending on how well you make the gradiant.
