Infrared sensitive? (M9 CCD)
The M9 is not responsive to true infrared, though it does have a tendency to a magenta cast with some fabrics, as these pictures show. Be sure to read the comments that follow the images.
While I can see a trace of purple in the pack in real life, and the D3x faithfully records what I see, the Leica M9 renders the gray pack with a strong magenta cast.
To determine if the effect is due to infrared, the second image uses a B+W 489 infrared blocking filter, which can be seen to make no difference. However, the spectral cutoff of the B+W 489 is gradual, and this magenta cast could still be due to near infrared (650nm -750nm). The D3x has garnered kudos for its color accuracy, and it matches what I see by my own eyes (third shot below).

- Make better images by learning how to get the best results right away.
- Save money by choosing the right lens for your needs the first time, particularly the Summilux/Summicron/Elmarit choice and/or Zeiss ZM.
- Make better images, a sort of “cheat sheet” saving yourself months or years of ad-hoc learning. Processing parameters are discussed and shown.
- Jaw-dropping image quality found nowhere else utilizing Retina-grade images up to full camera resolution, plus large crops [past 2 years or so].
- Real world examples with insights found nowhere else. Make sharper images just by understanding lens behavior you won’t read about elsewhere.
- Aperture series from wide open through stopped down, showing the full range of lens performance and bokeh.
- Optical quality analysis of field curvature, focus shift, sharpness, flare, distortion, and performance in the field.
