Hi all. i just started my process of home scanning. I scanned with much satisfaction a few bnw rolls and today i started with color. Unfortunately the scans came out not very good. I think the problem is i shot this roll with a camera that has a not very well calibrated light meter and it tend to underexpose so i got a lot of noise/grain. I think it is due to negative lab pro which in the conversion process because if i make the curves inversion i got a underexposed image and no grain. Is this correct? Film: kodak gold 200 camera: leica SL Lens: sigma 70 macro 2.8 art Settings: iso 100, f5.6 1/80 +1 exposure compensation Here is an example: the firs screenshot is from an image converted with NLB, the second one is a curves inversion > **[1 hosted at ImgBB](https://ibb.co/gM3FwcCx)** > > Image 1 hosted on ImgBB > **[2 hosted at ImgBB](https://ibb.co/21LP3VQP)** > > Image 2 hosted on ImgBB ---

It would be helpful to see the negative, but an underexposed photo will inevitably show more grain and additional color noise in the conversion.There are ways to reduce the visible grain/noise by tweaking what information from the negative NLP is reading. NLP cannot work magic though.
