Something as simple as white balancing a camera can make a huge difference in how your video is perceived by those watching. Does your subject look orange? Blue? Green? I hope none of the above. They should look the same as they do in person. Red, yellow, black, or white.
Perhaps it’s the fact that I’ve been a video engineer for 15 years and have been in the film and video industry for over 20 years that makes me feel this way, but when I’m watching a TV show or a movie and I see scenes cut together with coloring that doesn’t match, it makes me cringe. These are professionals and they should be getting this right. When this happens, it can cause people to get distracted and disengage.
