I know. It's in the manual (pp. 182ff). I've just never found it in the menu. It shows to be close to the tail-end of the Shooting Menu on the D850. I'll look again tonight. I used HDR all the time when I was using my D200 (not in-camera, though), but then pretty much stopped when I got the newer cameras and started using raw. Thanks for being patient as I look for it. To me, the usefulness is determined by how the camera does the tone-mapping to fit the finished product back into an 8 bit JPEG envelope.

I was playing around with HDR mode over the weekend in an attempt to deal with back-lit subjects in direct sunlight. I kind of gave up when I couldn't get the HDR function to enable on my D850 and also I read that this situation is better dealt with using bracketing.

So I'm testing out bracketing and I'm wondering if the intent is to be able to selectively stack the variously exposed images in post. Also, if I shoot in manual and get 3 frames of a scene at 0, +2, and +4, I presume this means that the ISO is adjusted and not aperture or shutter speed. Anyway, can I stack these in Photoshop somehow? I'd appreciate if anyone knows a good tutorial.

Related question. I imagine that if I want to use bracketing to deal with a back-lit subject such as a model in direct sunlight, that the success is somewhat dependent on the capture rate of the camera. At 7 or 9 fps for the D850, I'd guess that the subject and background should be pretty static for the stacking to work effectively in post.

Also, when setting up the shot, is there a way to tell how far underexposed, say the shadowed face of the subject is using the exposure meter in the viewfinder...to help decide what bracketing steps to use? Once you get past two steps the viewfinder no longer indicates how far the exposure is under/over. I guess I could count wheel clicks above a properly exposed background to get proper exposure on, say, the shadowed face of the subject.

TIA. I'm thinking I will buy Steve Perry's book and see if that helps.
