    Many more can be found at: http://luxal.dachary.org/webhdr/software.shtml
  • 40. Camera Settings
    Set to raw capture
    Color Space (default setting) @ sRGB.
    Turn off enhancements (I.e., no sharpening)
    Establish a “set” white balance (I prefer Auto)
    On manual/auto bracketing: Set for TV/Speed (shutter speed changes and not aperture)
    Experience & Testing Reveal: Set EV to -.3 (default),
    Auto bracket: 3 to 9 depending on camera @ 1 EV stop apart min.
  • 41. Camera Settings
    Typical AB is 5 frames at 1 EV apart per (Nikon)
    On most Canon (some Nikon) set for max of 3 frames @ 2 EV apart.
    ISO set as low as possible (I prefer ISO 100 or lower if camera has ability).
    Workflow: Most underexposed to most overexposed (if possible). Your choice!
    Lock Focus (When possible & plausible, use manual focus.)
    For landscape - f-8 or higher is recommended. I like f/11 or f/16.
  • 42. Next Steps
  • 43. Working The Image
    Download the image to your HD/External HD
    For today, the Desktop is the perfect location
    Open up your image browser (Bridge is great)
    Three ways to load files in Photomatix
    Drag & drop from Bridge
    Use the Lightroom 2.0 plug-in (sends them as TIFF files)
    Automate (batch processing)
    Generating the HDR (Radiance [.hdr])file.
  • 44. The Photomatix Pro Interface
    Click on “Generate HDR Image”
  • 45. Now… Click On Browse
    After the files are loaded, click on OK.
    The next screen shows the dialog box which appears after clicking OK.
  • 46. Set your parameters:
    • If working from 1 file, Align source images is not necessary.
    • 47. Use “matching features” as it also does rotational correction.
    • 48. I do not always use the “Attempt to reduce ghosting artifacts.” It depends on what I am after. However, it is good to leave it checked by default and remove the check mark if not needed.
    • 49. Make adjustments to white balance if needed.
    • 50. My color space is set for Adobe RGB (1998)
    • 51. Click on OK
  • Your Next Window is an HDR Viewer
    1) Before starting the Tone Mapping sequence, click on: File/Save As/.hdr should be in the dialog box/Save.
    2) Now click on “Tone Mapping”
  • 52. The Photomatix Pro Workspace
  • 53. Detail Enhancer Settings
    • Strength: Controls the strength of the contrast enhancements; locally and globally.
    • 54. Color Saturation: Controls the saturation from grayscale to pure color in the image.
    • 55. Luminosity: Controls the compression of the tonal range, thereby affecting the global luminosity range. The higher the setting, the brighter the mid-tones and shadows – adds contrast as well.
    • 56. Light Smoothing: Controls the smoothing of light variations (two methods: slider or light mode).
  • Detail Enhancer Settings
    • Microcontrast: Sets the amount local details are accentuated.
    • 57. White & Black Points: Controls the clipping points of the shoulder and toe of the tonal curve.
    • 58. Gamma: Adjusts the midtone of the image.
    • 59. Temperature: To the left is cooler; to the right, warmer.
    • 60. Saturation Highlights & Shadows: Enhances the primary saturation control allowing fine tuning.
  • Detail Enhancer Settings
    • Micro-smoothing: Used to smooth local details enhancements.
    • 61. Highlights Smoothing: Use to keep highlights from turning gray or to reduce halos around objects.
    • 62. Shadows Smoothing: Reduces contrast enhancements in the darker areas of the image.
    • 63. Shadows Clipping: Controls the shadow clipping and is handy for reducing noise in dark areas of an image taken in low light.
  • After Tone Mapping… Process The Image
    Click on “Process” after Tone Mapping your image
  • 64. Processing the Tone Mapped Image
    The Magic is in the Tone Mapping!!
    When Photomatix completes the processing phase, it will provide a preview image in the window. You are now able to tone map the image again if you so desire.
    If you like what you see… File/Save As/TIFF (16 bit). There is a check box on the Save As window to “Open in Image Viewer” and I keep this checked with PS4 as the default program.
  • 65. Adobe Photoshop™
    Use Photoshop to generate an HDR file
    It’s great – wonderful in fact – at combining files accurately
    It STINKS – and I’m being very nice – at tone-mapping
    To generate an HDR image file in PS…
    Go to Bridge
    Tools/Photoshop/Generate HDR (see next slide)
  • 66. A Little About Photoshop™
  • 67. HDR Previewer in PS
    Click on OK
  • 68. Let PS Do Its Thing…
  • 69. Save As Radiance (.hdr)
  • 70. What Now?
    Open the Radiance (.hdr) file in Photomatix Pro and, you guessed it… Tone Map the image anyway you like it.
  • 71. Questions?
    More Importantly…
    THANK YOU!
