Overview of Using Camera Histogram vs Incident Meter

In the field, metering under varying lighting conditions can be a challenge. The camera histogram can guarantee a near perfect exposure, an incident light meter cannot do so in general.

During the years I shot 4X5 and 6X17, I created a frustratingly large number of too-dark or too-light exposures using an incident light meter. As simple as the idea sounds, an incident light meter can be quite difficult to use when the lighting conditions are dynamic(or the subject is lit differently from where the meter is!), and some scenes require a judgment call that only long experience can yield. Hence I usually shot three 4X5 sheets per shot, developed one, then pushed or pulled the others as desired based on the first one. Typically the push or pull was no more than 1/3 or 1/2 stop, a trivial difference to correct with RAW on a digital camera, but very significant with film.

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”.
