The Humanities and Social Studies building courtyard at UCSB, in HD.

This HDR photo posed a little more challenge then previous ones. In the past when faces with these I did not really like the photo enough to dedicate the time to find a way to solve it. The problem: the night sky.

With many HDR photos taken at night the night sky turns into a mess of noise and artifacts, a result of the processing software. To avoid these using Photomatix Pro I upped the Shadow Clipping and then adjusted the remaining settings to make up for this. In the end this is what I used:

  • Strength: 80
  • Saturation: 55
  • Luminosity: +4
  • Light Smoothing: High
  • Microcontrast: +10

Tone Settings:

  • White Point: 0.604
  • Black Point: 0.161
  • Gamma: 1.23

Color Settings:

  • Temperature: 0
  • Saturation Highlights: 0
  • Saturation Shadows: 0

Smoothing Settings:

  • Micro-smoothing: 2
  • Highlights Smoothing: 30
  • Shadows Smoothing: 0
  • Shadows Clipping: 50

These settings worked well and I used this preset for several other photos taken in the same night.

    Goleta dock tone compressed.

    Last Friday I took several pictures of a dock in the distance lit by several lamps and mainly moonlight. I thought it would make a great high dynamic range photograph. I ran into problems as the middle exposure was at twenty seconds so I had to use a timer and the bulb setting to get higher f-stops. Even then I only went two stops above instead of three or sometimes four that I normally do. I did not think that this would cause problems.

    Well, it did. Several hours with Photomatix details enhancer did not yield any appreciable results. Instead I turned to the other tonemapping method of Tone Compression. With the following settings I get the photo above:

    • Brightness: 10
    • Tonal Range Compression: 9
    • Contrast Adaptation: -8
    • White Point: 5.30%
    • Black Point: 0.00%
    • Color Temperature: 0
    • Color Saturation: +1

    Another small benefit of Tone Compression is that it processes a lot faster then details enhancer.

    The same photo as before just slightly redone.

    As I was uploading photos to flickr I realized that I have not tonemapped any images in a while. And this the image above. I took this image and ran it through Photomatix Pro with the following Details Enhancer settings:

    • Strength: 100
    • Saturation: 60
    • Luminosity: +2
    • Light Smoothing: High
    • Microcontrast: +6

    Tone Settings:

    • White Point: 0.808
    • Black Point: 0.250
    • Gamma: 1.01

    Color Settings:

    • Temperature: 0
    • Saturation Highlights: +1
    • Saturation Shadows: 0

    Smoothing Settings:

    • Micro-smoothing: 2
    • Highlights Smoothing: 21
    • Shadows Smoothing: 22
    • Shadows Clipping: 0

    I have a few more similar to this one that I might go over in the next few days.
