Overview of Frame Averaging, Shooting and Workflow 📹

re: videos by Lloyd
re: frame averaging

Average identical captures to eliminate random noise and color artifacts, leaving detail intact. Averaging can be done for RAW and/or JPEG. The camera must be motionless, and the subject ideally will be still.

This video walks through the shooting process, processing and layering, and averaging the frames into the final image.

When/why/how

- best used for extreme dynamic range images
- for most images, proper ETTR (Expose To The Right) exposures suffices
- drastic reduction in noise of all kinds (except stuck pixels)
- shoot with remote release. Can also be shot with 4-frame pixel shift.
- shoot as fast as possible
- electronic shutter strongly advised
- do not touch the camera; all frames must expose without contact!
- subject motion will blur, but that is often OK

Diglloyd Making Sharp Images articulates years of best practices and how-to, painstakingly learned over a decade of camera and lens evaluation.

Save yourself those years of trial and error by jump-starting your photographic technical execution when making the image. The best lens or camera is handicapped if the photographer fails to master perfect shot discipline. High-resolution digital cameras are unforgiving of errors, at least if one wants the best possible results.

  • Eases into photographic challenges with an introductory section.
  • Covers aspects of digital sensor technology that relate to getting the best image quality.
  • Technique section discusses every aspect of making a sharp image handheld or on a tripod.
  • Depth of field and how to bypass depth of field limitations via focus stacking.
  • Optical aberrations: what they are, what they look like, and what to do about them.
  • MTF, field curvature, focus shift: insight into the limitations of lab tests and why imaging performance is far more complex than it appears.
  • Optical aberrations: what they are, what they look like, and what to do about them.
  • How to test a lens for a “bad sample”.
