Panasonic S1H Dark RAW Images

Gino Terribilini
I may be alone in this, but I recently did a couple shoots with my Lumix S1H and found that when I imported the RAWs into C1, they appear 1-2 stops darker than exposed for in-camera. When the images are first imported before the thumbnails are generated, the images appear as bright, flat images (like RAW data), then as soon as they are finished importing, its like a style is being applied and they go dark (though no style is selected in the import menu). I have messed around with the ICC curves, but they all require me to open the image's exposure. Anyone having similar experience or is there something I'm missing?

    I don't know the camera, but does it have a "protect highlights" setting?

    This is usually achieved by under-exposing the file by a stop or two, then the camera/Panny's Raw converter applying a curve to bring it back a nominal correct exposure.

    In Raw converters that don't recognise this setting, you simply present a very under-exposed file to the software.

    I imagine that Capture One would be in that category, in which case you need to turn the setting off in camera.

    Good idea- I always go through the settings and turn off any gimmicky settings like that and just combed through each of the menu settings to see if I missed a something hidden in a sub-menu, but wasn't able to find anything like that. Also just looked up "protect highlights" and S1H, but wasn't able to find anything helpful.

    Thanks for the theory, though- definitely sounds like that's what's going on especially since the first moment C1 acknowledges the image, it looks like a beautiful RAW image.

    It will initially display the "correct" embedded jpeg from the Raw before then showing the Capture One rendering, which is why I thought of the highlight protection idea.

    Not sure what to suggest next, but if you could make a Raw file available, I'd be happy to have a look.

    Are you shooting in v-log profile? If I bring a v-log profile shot into C1 it is very dark, looking at the luma curve everything is sitting in the left hand third of the chart. Upping the exposure by 3 times seems to put it back to normal.

    Other picture modes seem fine

    I have this same problem with dark RAW images on my Nikon D750. They appear bright in camera and for a second while importing, but quickly turn very dark. Not sure what is going on... I am shooting with a flat RAW profile in camera.

    I was.  I did a test with the other color profiles (like RAW+v-log and RAW+CINEV) and found the non-log color profiles dealt with my exposure problems properly.  Increasing the exposure 3-stops messed with the quality of the color immensely, so I'm glad I was able to figure this out.

    I was coming from Canon where color profiles weren't something I had to deal with (RAW just meant RAW), so I assumed that was the case with Panasonic.

    I don't use Nikon, but I would assume your problem is similar.  Try keeping the image as RAW, but try the other color profiles to see if that helps.
