Okay, so last saturday I shot another Olympic weightlifting event, this time with my newly purchased 50 f/1.8 II lens. I've been capturing and working on the some 3500 images and I've noticed a trend I didn't see in camera that day... from shot to shot, the color cast or white balance seems to change... one shot will be perfectly white balanced with good skin tones, the next one will be slightly off, with the skin tones way to pale. All the colors seem to be affected, not just the skin tones, the green banner in the background is as well... I'm confused as to why this is occurring, I can fix this in post, but it'll be a pain in the ass. Does anyone have any idea why this would happen? Maybe a different amount of light hitting the sensor? or something, I am baffled. here are two back to back shots taken, unprocessed save for my watermark. if anyone can offer an explanation, that would be awesome, I'm intrigued by this.
