Exposure for Optimal Image Quality: Camera Histogram + RawDigger 📹
re: videos by Lloyd
re: ETTR and RawDigger
Interpreting the camera histogram for optimizing capture, then cross-checking exposure quality using RawDigger.
An optimal exposure vs not hugely outweighs any silly metrics about camera noise levels. The latest and greatest camera sensor might improve by 1/10 stop or 1/3 at best, but typical under-exposure errors are in the range of 1 to 2 stops most of the time!
In an era where 1/10 stop improved noise behavior is listed as a feature worth calling out, most users are often giving up 1+ stops dynamic range and noise control because of stone-age exposure metering!

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”.
