Using light coming in a window can give your some very neat photographs of people and table top subjects.. In this day and age of super fast film and ISO’s on digital cameras you rarely need to use a flash indoors.
I can remember “way back when” when you had film speed with an ASA rating of 24 and 32 and then plus X came along with a rating of 100. I believe it was in the early 50’s that Kodak came out with Tri X film which made it possible to take photo indoors without a flash…it was called “available light” photography.
Using window light on your subject’s face provides a pleasing light without the harshness of a flash. I prefer using a south window which will have more light , but actually any window will do.
Have the light coming in behind you or from a side and have the subject facing the window. Do not have the sunlight fall directly on the subject but the light that is created from the sun..sort of like taking a photograph outdoors under a tree in the shade.
If you have a camera that the flash goes off automatically if there is not enough light, you will have to cover the flash with your hand or a piece of paper so it will not flash. That way your camera will automatically set itself for the light that is around you. You folks with digital cameras may have to do the same thing if your camera is set to automatic and the flash goes off with a minimum of light.
If you have a camera that you can set on manual, do that and adjust your shutter speed to a slower speed to let more light enter the camera. You can vary the f-stop as well.
If you are taking a photograph of a person, move the individual around so that you can achieve full light, and three quarter lighting and evening one quarter lighting on the face. See which you like best.
You can even do table top photograph if you move the table close to the window and let the light flood the subject. Practice, practice, practice until you have the concept down. I have included three photographs with this blog, The person on the back of the chair was facing large north windows while the child with the crayloas was looking towards a south window. With he flowers in a jar, the light was actually hitting the back of the jar making it more transparent.
