Field Example (San Francisco, Canon 1Ds Mark III)

Resolution charts are one thing, but a real-world image is instructive. Images taken on the 21-megapixel full-frame Canon EOS 1Ds Mark III.

The demands of 21 megapixels are significantly lower than with a 36-megapixel (Nikon D800E) or higher resolution camera, and vastly lower than the demands of a 24-megapixel cropped sensor “DX” format camera, with its tiny photosites (which scaled up to full-frame would be 56 megapixels).

The San Francisco, In Progress image is used for this example. It represents a real-world image where optimal image quality is not necessarily achievable: atmospheric haze reduces the contrast, and atmospheric distortion lends a wavy look to the detail. Other real-world images have limitations as well, especially depth of field. So this image represents an everyday outdoors shooting situation, as a counterpoint to perfect test conditions.

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”.
