5.4.2 Image capture (continued)
5.4 HDR workflow (continued)
Step 1: Take a test image to
determine exposure
Example:
Exp1=1/800s
Exp2=1/100
Exp3=1/13s
Do not use “automatic white balance” as this will create different colour
temperatures and hues for every image. As a consequence, the HDR
mixing will lead to artefacts.
Either take an image with medium exposure and optimise the histogram or create a
fast exposure and reduce the light source (sun) to the minimum. This will determine
the base for bracketing.
Step 2: Set the white balance
There are 2 possible options for white balance:
• “choose in picture” – for point white balance
• “presets” (direct sunlight, shade, tungsten, fluorescent)
The above white balance options will keep the coefficient values exactly the same
for every panorama. “Choose in picture” is the most visual or intuitive tool.
There is always the possibility to readjust the white balance afterwards. However,
the fastest and most accurate workflow is to have a uniform white balance from the
beginning.
