Lua script for automatic color correction

Hi ! Thanks for you answer. Your standalone app (Retroshine) works very well, by the way.

It does a very good job with old slides. Not that they were badly scanned, I just did it, but the slides were damaged and lost some colors. It’s better in this area than what Negative Lab Pro does with positive pictures (it tries to correct them as well). And just for fun, I tried your tool with inverted but not corrected negatives, and the results are interesting. I prefer the approach of Negadoctor in this area, which provides more consistency between pictures, but your curve approach works pretty well as well for this.

No, there is nothing in the history. Yes, I have the onnx file and selected it. I downloaded it again, gave him a _1 suffix and tried to use the new one, but it still didn’t work.

I don’t know what to expect when calling the autolevels in the cmd, in the end he asks me which software I’d like to use to open the file, I answer darktable and nothing special happens, he runs darktable and no more sucess inside dt.

But I use the last weekly build from Bill Ferguson : here Maybe that’s what causes the problem ?
