Why hasn’t anyone produced a digital camera (or any camera, really) with a built-in bubble level? I’m sick of people giving me pictures that are tilted at an angle. It doesn’t have to be a big angle either. If the horizon is just a couple of degrees off, the picture looks odd.
Digital cameras have made this worse with their little viewfinders — people are just sorta looking at the picture for composition from a distance of about a foot, and they don’t notice if the camera is tilted to one side or another. Yes, you can fix these things in post-production, but a bubble level would make it so much simpler.
