12-Bit was the usual for many uncooked information within the early days. Then, someplace round 10 years or so in the past, most of them began switching as much as 14-bit. There are a couple of that also solely shoot 12-bit and a few give the choice of each. Why? Nicely, the decrease bit depth permits for higher efficiency because of the diminished knowledge throughput necessities.
Everyone knows to shoot uncooked quite than 8-bit JPG, however is there that a lot of a giant distinction between 12-bit and 14-bit? On this video, photographer Michael Brietung wished to seek out out. So, he shot similar pictures utilizing his Canon EOS R5 in 14-bit utilizing the mechanical shutter and 12-bit with the digital shutter to see if he may see any distinction in any respect.
Michael shoots a number of collection of pictures together with 5 stops overexposed, 5 stops underexposed and appropriately uncovered. The photographs had been then corrected in lightroom, including or eradicating publicity the place required and tweaking the degrees to make them match with the appropriately uncovered pictures. Then he pixel peeps a bit (as he freely admits) to see if there’s any actual noticeable distinction.
And, surprisingly, no there wasn’t all that a lot distinction between them actually. No less than, not till you appeared on the one 5 stops underexposed, the place the variations had been fairly apparent even when the picture was zoomed out to see the entire thing on display.
Positive, you’re by no means deliberately going to underexpose a shot by 5 stops, however for those who’re working in a excessive distinction scene, some elements of the scene could be that darkish simply to protect the highlights. When you’re pushing the extremes of your digicam’s dynamic vary functionality, it means you’re going to have the ability to pull extra correct element and hues out of these shadows rather more simply for those who’re taking pictures 14-bit uncooked quite than 12-bit.
When you’re not taking pictures excessive dynamic vary scenes, you could not discover a lot of a distinction, if any in any respect. And in case your digicam provides efficiency advantages by taking pictures 12-bit uncooked, you could be higher off taking pictures that as a substitute. It ought to take up rather less area in your onerous drive, too.
Do you see a distinction between 12-bit and 14-bit uncooked for what you shoot?
