- # Magic Lantern cr2hdr tool - customized
-
- This directory contains files to compile Magic Lantern cr2hdr dual ISO conversion tool on Linux (Arch Linux preferred).
-
- Patches in this directory have some custom features which are not found in the original cr2hdr version. These features include:
-
- - added support for `--dry-run` parameter for cr2hdr
-
- - When `--dry-run` is enabled, the actual conversion is not done. The tool just checks that conversion is possible
-
- - This is handy in scripts where we just want to distinguish normal single ISO CR2 files from Dual ISO ones and then perform some custom action
-
- - added support for `baseline` metadata export. Following tags are exported:
-
- - Baseline Exposure (sample value: 0.25)
-
- - Baseline Noise (sample value: 0.8)
-
- - Baseline Sharpness (sample value: 1.2)
-
- - These values affect RAW image post-processing
-
- - [More about the meaning of Baseline values](https://www.rawdigger.com/howtouse/deriving-hidden-ble-compensation)
