I needed a professional headshot done within a day. The photographer was a super nice dude, super professional, and extremely detailed.
I was expecting to walk in for a few minutes and take a few shots, but got so much more -- I got full on coaching on what to do with my eyes (apparently it's common for one eye to be bigger than the other, and so I should widen an eye to compensate); eyebrows ("a little more pressure!"); mouth (various positions); head and chin ("head out, chin up"). We took maybe 30 or 40 shots to start, and sat down and discussed what we liked and didn't like; and with my newfound understanding, we went and took another dozen or so.
He even got rid of a massive zit on my face.
I had results by the end of the day. Overall, I was very pleased with the experience, and would recommend John's Headshots to anybody.
