Images converted with AccuRaw Monochrome Beta, with sharpening set to 1.00 / 0.80 followed by Topaz Infocus 0.20 / 0.60. This is not a magic combination based on investigation so much as a quick ad-hoc approach to making the images look reasonably good. More or less sharpening is also better depending on f-stop (diffraction). Overall contrast was also adjusted for a good black/white range.
Some images shot with filtration (red or green or yellow), but this information went unrecorded. Generally speaking, a red filter seemed beneficial for seeing deeper into the water. No filtration used for the 15mm lens as I had none in 95mm filter size.
The conversions here do not necessarily preserve all highlight detail; in some cases this was “let go” for overall tonality. A serious student of monochrome would work out appropriate subtleties for each image when converting.

Diglloyd DAP is DSLR-oriented, but also contains workflow and other topics. Much of the focus is on Canon and Nikon but also Pentax and Pentax medium format.
Special emphasis is placed on lens evaluation, focusing on Canon and Nikon and Sigma lenses, but with a few others like Rokinon/Samyang.
- Make better images by learning how to get the best results right away.
- Save money by choosing the right lens for your needs the first time, particularly some of the new Sigma Art lenses vs Nikon and Canon.
- Workflow discusses image organization, raw conversion and post processing. Many examples show processing parameters for direct insight into how the image was converted.
- Jaw-dropping image quality found nowhere else utilizing Retina-grade images up to full camera resolution, plus large crops [past 2 years or so].
- Real world examples with insights found nowhere else. Make sharper images just by understanding lens behavior you won’t read about elsewhere.
- Aperture series from wide open through stopped down, showing the full range of lens performance and bokeh.
- Optical quality analysis of field curvature, focus shift, sharpness, flare, distortion, and performance in the field.
