High Dynamic Range Photography See this web page for a description of High Dynamic Range photography. This is an excellent resource book for HDR photography: Complete Guide to High Dynamic Range Digital Photography, by Ferrell McCollough; Published by Lark Books, a Division of Sterling Publishing Co. ISBN-10: 1-60059-196-5 ISBN-13: 978-1-60059-196-9 Complete Guide to High Dynamic Range Digital Photography, by Ferrell McCollough Published by Lark Books, a Division of Sterling Publishing Co. ISBN-10: 1-60059-196-5 ISBN-13: 978-1-60059-196-9 The following information is my listing of information in the above book, so I can find the information faster. Page & Topic20 example histograms and photos (RAW & HDR) 39 camera settings 47 adjustments to avoid, and allowable 52 tone mapping workflow 54 grain vs noise 58 controlling grain enhancements 61 tone compressor vs details enhancer 69 HDR software 73 software comparison 86 post-processing HDR images 87 blending with layers & masks 97 judging contrast 102 number of images 110 noise & number of images 115 ghosting 123 flash merging 137 HDR panorama workflow 143 single image tone mapping 159 regions of extreme brightness 161 including the sun 162 including the moon 165 macros & flowers 166 HDR & snow 168 night & low light HDR 170 extreme tone mapping 174 HDR portraits Tone mapping workflow The default Photomatix Pro tone mapping operator is Details Enhancer. Click the Default button to place all slider in their starting positions. Step 1: Set Gamma. Set the Gamma slider so midtones fall in the middle of the histogram. Step 2: Set Strength and Light Smoothing. For the look of a traditional photo, move the Strength slider to the left in the range of 25 – 50 and Light Smoothing to the High or Very High. You may find that a Strength setting of 50 – 100 is more desirable. Step 3: Set White Point and Black Point. These add global contrast to the image. Typical settings are low-to-middle. If low settings are used, then post-processing of contrast may be needed. Step 4: Set Microcontrast and Microsmoothing. For an image with large small-scale contrast, set the Microcontrast to 10 (right) and lower the Microsmoothing (left). For an image with softer transitions in local contrast, lower Microcontrast to –10 and raise Microsmoothing to 30. Avoid moving both sliders full right or full left, as they tend to cancel each other out. The book’s author typically has a Microcontrast setting of 0 – 7 and a Microsmoothing setting of 0 – 10. See the referenced book for much more information.
Thank you for Bob Lott and his HDR presentation to the Chester County Camera
Club, for getting me started on using HDR photography. |
