If you want to practice portraits at home, but don't want to spend a fortune on peripherals for a home studio, this is for you.
You can do a lot with a little, when it comes to photography — we know this. But still, people don't necessarily appreciate just how much you can do without spending much money. Yes, you'll need a camera, but your phone could do, and don't be embarrassed if that's the case. Once you've got that, the budget is really going on some sort of backdrop, but you could even work around this. In this video, Adorama uses a 5-in-1 reflector as a backdrop which is something I've done several times. However, you can substitute in really anything, depending on what you're going for. If you have any black felt, or even better, crushed velvet, you can go for that low-key look. Then, for light, this video is opting for all natural.
A doorway is the light "source" of choice, and it's not a bad one either. The most common approach is a window — the bigger the better — and setting up in front of that. However, if you can find a doorway that leads to the outside, with a hallway inside, you could be perfectly situated to create some surprisingly great portraits.
