This is a super easy setup using only one large octobox placed almost in the center. The white background reflects lots of light from every direction, so there is no need to use fill lights. I usually do dark backgrounds, but it was refreshing to try out something different this time.
I have used a relatively (at least compared to my usual settings) large F-stop for this so that all faces are in focus.
The pictures were made in the a Hamarits photostudio in Budapest. - It's a decent, clean and professional photostudio but the owner was working in the same area as the shoot so I wouldn't recommend it if that bothers you or your models.
