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.


- 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”.
