In the Field

With both the Canon and Nikon GPS units, tree cover in a moderate canyon did not seem to have negative effects on the functionality of either brand. Deeper canyons and/or heavy tree cover and/or a non-ideal GPS constellation might alter that behavior (the available GPS constellation can be good or not so good, depending on location and time of day).

With the Nikon D800E + GP-1 stowed in my hip-pack, the GP-1 would take 10-15 seconds to reacquire the GPS signal after pulling it out of the pack. I also noted that if I took a picture right away, that the reading would be off just a little; it is best to wait that 10-15 seconds for the current reading to stabilize if the camera has just been pulled out of a pack. In short, this means that for consistent readings, one should not carry the camera in a pack, and that the camera should be set for continuous operation (GPS => Auto Meter = Disable), so that the unit always has a “fresh” GPS reading. Or some patience is required before each image. Ditto for turning the camera off between shots.

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.
