Experimentation is your friend when it comes to learning about photographing with window light. It is not a mean feat to begin with, but practising with light from various times of the day will give you face-on evidence of what you will be able to achieve with some experience. Unlike the old film cameras, digital photography actually lends itself to absorbing natural light in photographs, which reflects off the subject.
Use white balance to your advantage – If you set your white balance levels to around 6000k then you will see a tone with a warmer feel. You can use an electronic flash to create a similar result, but enveloping both tools together could see some beautiful shots. By increasing your white balance even further, you can vastly improve the previous results achieved with colder natural lights from under the shade of a tree for example.
What time of day is best to shoot? If you wish to achieve images with a warm looking tone, try using light from the sun late into the evening. The sun is redder and emits duskier tones onto your subject naturally; all of which can be adjusted by using your white balance.
Experiment with light sources – Instead of simply standing your model or subject in front of a fully open window, use the drapes or slatted venetian blinds to create additional effects. Less light will be able to creep through the slats of the blinds, but they will however, create a striped shadow effect, which can be very becoming on a models face. This works best when it is very bright outside of the window, as this is required to create shadows that are more dramatic.
Avoid direct sunlight – As you would when you have fair skin and wish to avoid being burnt, avoid direct sunlight when photographing indoors also. Instead, sit your model slightly away from the window and reflect the natural light into them; this creates a softer and more delicate effect, which in turn is much easier to work with also.
