Hi, my name is Kat and I am a geologist with a small, environmental consulting firm. I work at a drill-site, where I take photos of sediments (dirt...) every 5-ft, using a camera stand to make sure the photos are consistent. We use a gray card in every photo and a Canon Ring Flash. We post-process the photos using Photoshop.
I am newly in charge of post-processing these photos and they are INCREDIBLY inconsistent! My problem is that there are several geologists and although we all use the same model camera, because of light changing with weather and throughout the day, user error (I have some older coworkers that struggle with technology), and camera settings, our photographs often are dark and blue tinted, or sometimes over-exposed using the same settings.
I have been trying to learn what I can to find the best settings, but my supervisor wants to use only one setting that is unchanging, despite changing environments, otherwise, she thinks the photos will be too inconsistent among different geologists.
Is there a setting I can use that will reduce the amount of post-processing (especially color)? Or any other advice??
Here are some examples of samples taken from the same camera with the same settings:
Thanks for any help or advice!!!
