Aperture Series: Decomposing Pumpkins (Canon 5DS R)

This very close range scene close range bokeh, vignetting and sharpness.

Decomposing Pumpkins

The deer (oversize ground rats IMO) ruined my pumpkins in 2015, eating chunks out of them (as well as seriously damaging the vines) and consuming the largest pumpkin almost entirely. These pathetic specimens are the best I could do. They were supposed to be giant pumpkins. Oh well.

Adobe Camera Raw 9.3.1 (520). Camera Profile = Adobe Standard.
Series is EV-matched with minor adjustments for small variations in lighting.

Observe how vignetting at f/1.4 and f/2 draws attention to the pumpkins, dramatically emphasizing them and increasing the apparent contrast. This can be put to good use with some subjects. By f/2.8, much of the effect is gone.

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.
