Think background first. What story do you want to tell? Epic background, big mountains. Looking to deliver a sense of grandeur with your subject. Go big! f/22 or higher if you have it.
I understand that he's using depth of field to talk about keeping the background sharp. But even at a modest f/8, the hyperfocal distance for most common scenarios is only a few tens of feet... more than enough to get a mountain range in.
I also understand that wider apertures reduce sharpness... but a few stops down from wide open is usually enough.
And obviously, you can use a smaller aperture to reduce the light. But f/22 seems pretty tiny even for a bright day.
So what other reasons for using a tiny aperture exist?
