RAW file uploaded to my computer (macbook, iphoto) with a dark tint

[SpacemanSpliff]

Hi guys,
I uploaded a bunch of pics to my laptop that were shot with a D5100 and a small handful of them uploaded with a very dark tint, like in the attached pic. Just wanted to see if anyone's come across this so that I can find the root cause of this.

Thanks all

EXIF data would be nice to see.

That's pretty much what a Raw image data file looks like before it has been run through a Raw converter and been demosaiced, gamma encoded, and tone mapped.

Thats normal, its just underexposed, the camera usualy post-processes these and corrects when it writes to jpeg. Make sure you are paying attention to your light meter.

the problem is that the picture wasn't underexposed when i took it, but it became tinted like this when i uploaded to my computer. i subsequently wiped the original file from my sd card before i noticed this. is there any way to post-process it back to a good picture?

The screen will have been showing you the (corrected) jpeg.

I WOULD SAY THAT THE PEOPLE were underexposed about 1.7 EV. The overall, totality of the scene might has appeared correct to the light meter, OR after the RAW data has had a tone curve applied to it, and the image data analyzed, and modified for a JPOEG conversion.

It's possible that your computer's software in not fully up-to-date, and cannot translate that camera's RAW file data properly, or that the software is set to show AS-SHOT images, and not show an adjusted image. So many factors at play here.

HERE is what I mean by applying a tone curve and an exposure adjustment:



Now, I was forced to work with a seriously compromised 8-bit JPEG image, and this is the quick result. If I would have had a 12-bit or 14-bit RAW Data file, this scene could have been made much better with the FULL data set.

^Wow dude that was amazing lol! I didn't think these were salvageable at all; I'm going to go back and fiddle with my computer until I learn this stuff.

Thanks all for the help
