Portraits with landscape backgrounds.

What aperture would you use when youre shooting people somewhere like the grand canyon?

Usually i use my 50mm f/1.8 and just open up that aperture for portraits...

But i was thinking... when you do that, you cant even tell the grand canyon is in the background.

What would you guys do? Use a small aperture, and get all of the background? Maybe step back and do a portrait thats not just chest-to-head, but more full body shot? Or maybe an aperture in between like f/8 or something?

I'd say F8 myself. Enough light for decent shutter speed. Enough depth of field, and not too shallow either for completely blurring it out

Or just try some variation whilst you're there. See what works

Myself I would have it set around f11. As soon as you get there just take some test shots with different settings then do some chinking and go with the setting with the look you are going for.
