I know I’m going to get a little confusing here, but there are 2 types of HDR that we are talking about here.
the first type is HDR of exposure. Where you stack multiple exposures and pick the best exposure in each parts. So let’s say you take a picture of a person in front of the sun with a nice cloud formation. If you expose for the clouds, the person will turn into a black Silhouette, but the clouds will look great. If you expose for the person, the clouds will just fade away into white because the camera over exposed them. If you take the best exposure from each and combine them, you get a classic HDR photo. The iPhone takes multiple exposures super quick every time you take a picture and combines them together. That’s always been what HDR was way back before OLED technology.
The other type is stretching the full dynamic range across a wider brightness/color gamut. It’s what what makes the bright areas “glow” on your Screen. An OLED panel is not limited to an overall brightness like an LCD (unless you use area backlighting). So the OLED panel can display, in one image, a full black to the brightest nitt level.
What Apple is doing from my guess is doing the first HDR and adding that brightness map on top to simulate the second. And for all intents and purposes, it works.
Over time apple has tweaked the HDR prosessing with its image processing engine as phones get faster. so what you saw on your phone may not look the same on the new. I seem to always find the new phones pictures meh until learn the quirks of the new and learn how to use it.
Now you can turn off HDR in settings/camera under smart hdr. Give it a try and see how you like it.
Great detail, lostless, thanks.
So what I want to do is toggle. I want the Type 1 HDR (clouds example) when I shoot people and places, the usual family photos and such. And in that scenario I'm good with the Type 2 HDR (top nit level example) as well. Outdoors, family party, HDR, why not. But when I shoot my cars, I don't want any HDR at all.
So....if I have HDR turned off in both Settings > Camera and Settings > Photos, is it true then that when I want to take an HDR photo I merely need to toggle it 'on' in the actual Camera viewfinder and not have to go drill through the settings each time? In Camera > Settings it talks about "Smart HDR", so does that turn off all HDR or just some derivative that's smart?
