Using the Dehaze filter for Monochrome Images

The Dehaze filter in Adobe Camera Raw has the effect of increasing contrast in both highlights and shadows. While its effects quickly become overwraught with color images, in monochrome it can be highly effective at dealing with relatively low-contrast subjects.

Using negative values, the Dehaze filter can also decrase contrast for a hazy effect. Examples of both usages are shown here.

For example as shown below, there is a lot of high-key detail of low contrast, to the point of making it difficult to see the animal tracks and subtle ripples in the sand. If during a brief period of the day one manages to get the sun strafing such detail just right—great. But so many times the light is not favorable and can never be favorable due to the angle and position. Here, I could only have had the balance of tones I wanted mid-day; later it would have gone mostly shadowed from the winter solstice sun. The Dehaze filter delivers the contrast and detail I was seeking.

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”.
