MakeHDR

MakeHDR is an OpenFX plug-in for merging multiple LDR images into a single HDRI.

Feature notes

• Merge up to 16 inputs with 8, 10 or 12 bit depth processing
• User friendly logarithmic Tone Mapping controls within the tool
• Advanced controls such as Sampling rate and Smoothness

Available at cross platform on Linux, MacOS and Windows Works consistent in compositing applications like Nuke, Fusion, Natron. 

How to Build

git clone https://github.com/Sosoyan/make-hdr.git && cd make-hdr
git submodule update --init

3. Fill the details of exposure times in seconds for appropriate inputs, i.e. for 1/250 shutter speed enter 0.004.

Node Parameters Reference

exposure_times

• 1-16: Shutter speeds of corresponding source input in seconds

tone_mapping

• exposure: Exposure aka f-stop offset
• gamma: Gamma correction
• highlights: Logarithmic highlights compensation

advanced

• show samples: Show sample pixels for debugging purposes.
• input depth: 8, 10 or 12 bit input image processing.
• sampling: Sampling count squared, 8 means 64 total samples.
• smoothness: Normalized smoothing of the response curve.
• log level: Log verbosity level of the node
