The sun in this one was a little desaturated, and I think it was due to lack of sufficient ND filters. I need to go down about 2-3 stops. The problem is, at around this point, IR light starts to flood the sensor, and ND IR filters are quite pricey, so for now I will tweak the color of the sun in post. It may seem “inaccurate” but as long as the desired light, colors and reflections are achieved, no harm has been done.

Trying a new bracket merge algorithm, seems to work better, but still room for improvement, especially regarding ghosting. Again this image suffers from ICE image stitch errors, which seem to be particularly bad across brackets, as if ICE changes the stitch for different brackets, even though it shouldn’t be.

I’m investigating ICE, which I use to stitch the panos, as it seems to be causing ghosting, I thought my tripod head was loose the first few times, but this time I made a POINT of keeping it solidly locked into position, and I am still seeing strange inconsistencies between the stitched brackets. I think I might give the Hugin pano-stitcher another shot as I have quite a few complaints with ICE.

This HDR captures the full dynamic range of the sun. It has a few weak points in the stitching and merging; however, it is still quite useful for most purposes.

I was inspired to create this HDR by Greg Zaal’s Mpumalanga Veld HDR which also captures the full brightness of the sun. Most of my workflow is based on the one Greg Zaal shared.

Keep a checklist of camera settings, I accidentally left auto white balance on, and had to correct it (Hurrah! for raw files)

Here is a quick checklist:

  • Card In Camera
  • No Lens Cap
  • White Balance
  • Media Format (turn raw on)
  • Manual Exposure
  • Brackets Correct
  • shutter and f-stop
  • Any Filters?
