Nikon D850 monochrome

Frame Averaging, Camera vs Photoshop (Moots MootoX YBB 29er)

This page looks at using multi-frame averaging for reducing noise on the Nikon D850 monochrome, but the same technique can be used on an unmodified camera of any brand, black and white or color. Well, the camera should have at least an EFC shutter for reasons of vibration.

Frame-averaged images are compared to a single shot, one from the camera itself, and one average in Photoshop.

The technique here takes remarkably little work, the main chore being taking the images, which could be fully automated at high speed, but Nikon screwed up its multiple exposure mode implementation.

Diglloyd DAP is DSLR-oriented, but also contains workflow and other topics. Much of the focus is on Canon and Nikon but also Pentax and Pentax medium format.

Special emphasis is placed on lens evaluation, focusing on Canon and Nikon and Sigma lenses, but with a few others like Rokinon/Samyang.

  • 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 some of the new Sigma Art lenses vs Nikon and Canon.
  • Workflow discusses image organization, raw conversion and post processing. Many examples show processing parameters for direct insight into how the image was converted.
  • 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.
