It depends.
Actors should plan on 2.5 to 3 hours. We are going to shoot multiple clothing looks, which means additional time for changing clothes and selecting outfits. If you are having your makeup done on site, that will add about thirty minutes.
For business/professional headshots, plan on about sixty to ninety minutes, since we are normally not shooting as many different outfits. If you are having your makeup done on site, that will add about thirty minutes.
