Bracketed High Dynamic Range Photography Workshop
Alexandr Reznik's Bracketed (HDR) Photography workshop at the IVRPA Tokyo 2018 Conference will deal with different techniques for capturing and processing bracketed photos, a process often referred to erroneously by the term “HDR”. The workshop will consist of both theoretical and practical parts, covering the essentials of making and evaluating expanded Dynamic Range (DR) images.
The theoretical part of the workshop will cover:
- The problem of modern sensor dynamic range. Modern cameras have 12-15ev DR but the scenery is less than 12 (no need for bracketing) or more than 15 (bracketing needed)
- Methods of expanding DR during shooting: bracketing, graduated filters, flash/reflectors
- Working with bracketed images:
- true HDR and tone-mapping
- automatic exposure fusion
- manual exposure fusion
- Photoshop “Blend If” and “Merge to HDR”
- Manual masks and automatic luminosity masks
- Combining different methods in Photoshop
- How many exposures are needed? Using 2,3,5,7 or more brackets
- Dealing with moving objects during processing of bracketed photos
The practical part of the workshop will require participants to have a computer with Photoshop CC and Ptgui installed.
The participants will be able to download sample files and make several stitches to compare results of different techniques.
