Previously, I tried to use Darktable for RAW format conversion, but it was a pity that I could not install Darktable on my machine. Later, I found another alternative tool, ImageMagick, but I found that it did not solve my problem. Since most of the RAW formats I shot were dark (I only have one camera, I am not sure if the other RAW formats are the same), I need to increase the exposure during the conversion so that it looks normal. But when I use ImageMagick to adjust the exposure (actually brightness), some of the highlights will overflow, making it difficult for me to adjust automatically. Then I found a library for decoding RAW format: libraw, which has the option of analog exposure adjustment, and can retain highlights to avoid highlight overflow when adjusting exposure. Unfortunately, the library does not have an executable tool, so I packaged a raw2jgp tool myself, which now solves my problem and enables my RAW photos to adjust their exposure during conversion. And there will be no highlight overflow. From this, I wonder if it is possible to add a custom environment variable of the RAW conversion tool, and the conversion script can be specified by the user, so that various conversion needs can be met.
