ETTR: Overcome Noise with Optimal Exposure, plus AI Denoise (Sony A7R V) 📹
re: Auto-ETTR Would Sure Be Nice — 2 Stops Below the Blow-out Was the Camera’s Advice (2012)
re: A CALL TO ACTION: Build Intelligent ETTR Into Digital Cameras
Want to give your 35mm camera image quality as good or better than the sensor of a much larger medium format camera? Or your medium-format camera to deliver its best? Read on.
We look here at getting considerably better image quality via proper exposure:
- Gross underexposure with camera metering from +0 to +5/3 stop exposure compensation (1 2/3 stops range of exposure).
- Noise levels at the metered exposure through the optimal exposure.
- Color images and the grayscale R/G/B color channel noise.
- Camera histograms and how they mislead.
- How much the AI Denoise feature of Adobe Camera Raw can help.

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”.
