Fotor vs rawhdr

Fotor has no write-up on Specifiction yet; its figures are above.

rawhdr is a free command-line package for combining multiple RAW photographs into a high-dynamic-range image. It also performs focus stacking from multiple images. RAW input can use formats known by the rawpy library, while output can use HDR formats known by imageio. The resulting HDR exposure follows the first RAW file supplied. Installation is documented with pip install rawhdr, and a Python API is available for exposure merging and focus stacking. Its exposure-scaling helper leaves out extremely bright pixels that may be saturated and very dark pixels that may be noisy. OpenEXR writing may require the additional freeimage library through imageio. Python 3.7 or newer is required. PyPI classifies the package as OS Independent, with Linux and API listed as platforms. It is licensed under the GNU General Public License v2 or later. PyPI names Felix Thaler as author and maintainer.
