Whoa. Jeff, your pizza looks incredible. Truly.
I'm pretty sure Adam Kuban shoots most of his pies straight down with a phone and they always look awesome to me.
Regarding that 👆 … Yeah, I do almost 100% overhead ("bird's eye view") shots with iPhone 5s, no flash. The iPhone has deep depth-of-field (pretty much everything is in focus in a shot), so to concentrate the eye on the pizza (rather than something in the background), I minimize what's in the background by leaving only table or countertop there. Plus, I just like the effect of seeing a circle framed nicely by a square (since I post most of my pics on Instagram these days). I try to shoot in daylight if possible. My best pics happen when I can shoot with available daylight on an overcast day, since the clouds diffuse the sunlight — no harsh shadows or high contrast. If I have to shoot at night, it ends up being some combo of CFL + soft-white LED in the kitchen. It's not ideal, but I do a lot of editing on the phone with the SnapSeed app.
Blah blah blah.
