Good evening experts. I have a Nikon D5200 with 50mm f/1.8 lens. Shooting fashion photography, and trying to get a white background. Would 3 point lighting with a white reflector as fill give me a good result ?
The short answer is yes, the long answer is depends.
Are you shooting full body? It is a little more difficult to make a smooth background.
Do you have enough space between your background to the subject? If you have considerable space you can put more power to the background light or use a big difused light.
Does the background light has enough power and amplitude to fill the background?
Do you have enough space between the background and the background flash to have an even ilumination? You can use one light in some cases.
Does the main light spills some light on the background? It can help to smooth the background. The same as the next question.
Is your studio painted in white? This last two options helps for a high key portrait.
Is the white reflector big enough?
Can you put the reflector it verey close to the subject? Probably remove it later in post pro.
Is the main light big enough, in the right angle and distance to spill light to the reflector?
Can you use aditional white boards to fill the subject?
Are you limited to use a white reflector? or Can you use a silver one?
How much shadow do you want on your subject?
Play with your lights, have fun and make tests considering all this variables: Difussion, distances, power, ambient.
You can use a second flash as a background flash and a rim light for example.
Use swich between one or two flashes for the background.
Bounce the flashes all over a small white room, or make a light tent for a full body.
Make a dramatic shadow with a single main light but white background.
Use some natural ambient light.
Again, play and have fun.
