Natural window light is a really useful effect for photographers. But the problem is that you don’t get window light everywhere you go. Fortunately, with the help of a large white-translucent reflector and an off camera flash, you can create this window light effect wherever you go.
You may consider two methods when creating window light effect using white reflector and an off camera flash.
You may either consider reflecting the light from the flash towards the large surface. It will offer you a relatively powerful light.
As the second option, you may configure the reflector to perform as a translucent. Then, you should place the reflector in the middle of the subject and the flash.
Regardless of the method you use, you should make sure to configure the hot shoe flash head with the widest setting. You can use the wide angle diffuser. At the completion of this configuration, it will cover the large surface area. No matter if the flash goes through the reflector or bounces back, it will deliver a really nice window light effect.
When it comes to a portrait, however, you may use the reflector by the side of the subject. Also, it is better to place it slightly above the subject.
