Another interesting study of Resolution ,Sharpness and Contrast. In this unmanipulated photograph, when seen at full size, no Aliasing can be observed in the Patterns of the Table cloth ( Something that would be very noticeable in diagonal Texture Patterns on Bayer type Sensors, specially in the absence of a Low Pass filter.) however there seem to be a hint of Near Infrared tinting of the Lower Tones in the shaded folds of the cloth .

These false coloration , due to heat waves ,could be corrected or filtered out during Post Processing, but I am planning on installing a Hot Mirror filter in Front of the lens, where it would not degrade its optical characteristics.

In my opinion the normal placement of the Infrared rejection filter , between the exit pupil of the lens and the sensor ,not only affects the light rays direction and contrast ,but it also creates a zone of infrared light Bouncing back and Forth, between the two ,that I rather not have. A hot mirror in front of the lens just rejects the I.R. light 45 degrees to either side of the entrance of the lens where it it becomes harmless. I welcome comments or questions in this regard.Luis
