diglloyd Advanced Photography (DAP) is a huge and still growing collection of high quality, timely, impartial research and reports by Lloyd Chambers on topics of interest to professional and amateur photographers.
New articles and updates to old articles are added frequently. The work that produces this research is funded through low-cost annual subscriptions within the reach of any photographer.
A subscription enables access to all the content in DAP and any future content for the duration of the subscription (e.g., one year). Even without updates, the breadth and depth of existing content in DAP would fill several books—a tremendous value.
A photographer’s perspective
Making real images is the focus of the vast majority of the material in DAP, with the efforts focusing on image making and the qualities that matter.
Obvious issues include resolution, noise and color rendition, but great attention is paid to issues like bokeh: how a lens draws or renders on real-world subjects.
Consistent with this approach, the number, size, and quality of images used in presenting the material is extensive and exhaustive. In a few cases deemed relevant, even RAW files are provided.
Learning not just reviews
DAP doesn’t just review cameras and lenses, it teaches along the way. Every review has areas of general photographic interest.
Some articles, like those on focus shift, are independent of brand, and focus on photography problems applicable to any brand.
Others, like the must-read The Sharpest Image, explore sharpness in ways that affect every brand, every camera, and every lens, though a small portion of the analysis is brand-specific.
Canon, Nikon and other brands
Coverage focuses on Canon EOS and Nikon, but a variety of other brands are also included; Sony, Mamiya, Hartblei, Voigtlander, Sigma, Leica and Tamron for example.
