This is my first contribution to PlayRaw, so please bear with me.
I’m currently playing with RT’s “Unclipped” profile as an update to my previous 16b HDR workflow.
Here are the new steps so far:
- Merge the bracketed shots with HDRMerge.
- In RT apply “Neutral” and “Unclipped”.
- In RT enable lens correction and capture sharpening (new feature by @heckflosse bound for 5.8).
- Adjust exposure to help stitching.
- Export to 32b float TIFFs.
- Stitch in Hugin 2019.0.0+ (important, since earlier versions will clip the result).
- Export to LDR TIFF. Although it says “LDR”, this will preserve the float and unclipped nature.
- For this very sample I chose to apply “Unclipped” again on the resulting TIFF in RT and exported it at 50% resolution to a compressed 16b float TIFF. This reduced the file size from 520MB to 30MB.
Of course there are stitching artifacts in the waves on the water. Those can be repaired later in GIMP.
If you lower the exposure by around 1.5EV the structure in the red clouds reappears:
Now, here’s the challenge: Lighten up the image so that the forground is visible without destroying the mood and without clipping the red in the clouds. RT solutions are preferred.
