Exposure for Optimal Image Quality: Adobe Camera Raw + AI Denoise, ISO 100 to 25600
This page looks at noise from ISO 100 to ISO 25600, and what the AI Denoise feature of Adobe Camera Raw can do about it, and how it affects image detail.
The camera was the Sony A7R V, but the same ideas seen here apply to any/all cameras.
Images presented at full 60MP resolution but also at 30MP and 15MP as a proxy to give a good idea of noise levels that would be perceived at different enlargments sizes.

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”.
