  37. 37. Processing software (e.g., Photoshop, PS Elements, etc.)
  38. 38. Desire to experiment
  39. 39. Something to photograph</li></li></ul><li>Software Available<br />Photomatix Pro (The Best) for Mac or Win - $99<br />Nik’s NEW HDR EFEX Pro ($179)<br />Hydra (up to 4 frames) aprox: $79<br />Dynamic Photo HDR (some “cool” effects) - $55 ($75 with PS4 plugins added for 8bit RGB editing)<br />Photoshpere (Mac only – freeware)<br />Many more can be found at: http://luxal.dachary.org/webhdr/software.shtml<br />
  40. 40. Camera Settings<br />Set to raw capture<br />Color Space (default setting) @ sRGB.<br />Turn off enhancements (I.e., no sharpening)<br />Establish a “set” white balance (I prefer Auto)<br />On manual/auto bracketing: Set for TV/Speed (shutter speed changes and not aperture)<br />Experience & Testing Reveal: Set EV to -.3 (default),<br />Auto bracket: 3 to 9 depending on camera @ 1 EV stop apart min.<br />
  41. 41. Camera Settings<br />Typical AB is 5 frames at 1 EV apart per (Nikon)<br />On most Canon (some Nikon) set for max of 3 frames @ 2 EV apart.<br />ISO set as low as possible (I prefer ISO 100 or lower if camera has ability).<br />Workflow: Most underexposed to most overexposed (if possible). Your choice!<br />Lock Focus (When possible & plausible, use manual focus.)<br />For landscape - f-8 or higher is recommended. I like f/11 or f/16.<br />
  42. 42. Next Steps<br />
  43. 43. Working The Image<br />Download the image to your HD/External HD<br />For today, the Desktop is the perfect location<br />Open up your image browser (Bridge is great)<br />Three ways to load files in Photomatix<br />Drag & drop from Bridge<br />Use the Lightroom 2.0 plug-in (sends them as TIFF files)<br />Automate (batch processing)<br />Generating the HDR (Radiance [.hdr])file.<br />
  44. 44. The Photomatix Pro Interface<br />Click on “Generate HDR Image”<br />
  45. 45. Now… Click On Browse<br />After the files are loaded, click on OK.<br />The next screen shows the dialog box which appears after clicking OK.<br />
  46. 46. Set your parameters:<br /><ul><li>If working from 1 file, Align source images is not necessary.
  47. 47. Use “matching features” as it also does rotational correction.
  48. 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. 49. Make adjustments to white balance if needed.
  50. 50. My color space is set for Adobe RGB (1998)
  51. 51. Click on OK</li></li></ul><li>Your Next Window is an HDR Viewer<br />1) Before starting the Tone Mapping sequence, click on: File/Save As/.hdr should be in the dialog box/Save.<br />2) Now click on “Tone Mapping”<br />
  52. 52. The Photomatix Pro Workspace<br />
  53. 53. Detail Enhancer Settings<br /><ul><li>Strength: Controls the strength of the contrast enhancements; locally and globally.
  54. 54. Color Saturation: Controls the saturation from grayscale to pure color in the image.
  55. 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. 56. Light Smoothing: Controls the smoothing of light variations (two methods: slider or light mode).</li></li></ul><li>Detail Enhancer Settings<br /><ul><li>Microcontrast: Sets the amount local details are accentuated.
  57. 57. White & Black Points: Controls the clipping points of the shoulder and toe of the tonal curve.
  58. 58. Gamma: Adjusts the midtone of the image.
  59. 59. Temperature: To the left is cooler; to the right, warmer.
  60. 60. Saturation Highlights & Shadows: Enhances the primary saturation control allowing fine tuning.</li></li></ul><li>Detail Enhancer Settings<br /><ul><li>Micro-smoothing: Used to smooth local details enhancements.
  61. 61. Highlights Smoothing: Use to keep highlights from turning gray or to reduce halos around objects.
  62. 62. Shadows Smoothing: Reduces contrast enhancements in the darker areas of the image.
  63. 63. Shadows Clipping: Controls the shadow clipping and is handy for reducing noise in dark areas of an image taken in low light.</li></li></ul><li>After Tone Mapping… Process The Image<br />Click on “Process” after Tone Mapping your image<br />
  64. 64. Processing the Tone Mapped Image<br />The Magic is in the Tone Mapping!!<br />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. <br />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.<br />
  65. 65. Adobe Photoshop™<br />Use Photoshop to generate an HDR file<br />It’s great – wonderful in fact – at combining files accurately<br />It STINKS – and I’m being very nice – at tone-mapping<br />To generate an HDR image file in PS…<br />Go to Bridge<br />Tools/Photoshop/Generate HDR (see next slide)<br />
  66. 66. A Little About Photoshop™<br />
  67. 67. HDR Previewer in PS<br />Click on OK<br />
  68. 68. Let PS Do Its Thing…<br />
  69. 69. Save As Radiance (.hdr)<br />
  70. 70. What Now?<br />Open the Radiance (.hdr) file in Photomatix Pro and, you guessed it… Tone Map the image anyway you like it.<br />
  71. 71. Questions?<br />More Importantly… <br />THANK YOU!<br />
