The farther the light source, the harder the light. The closer the light source, the softer the light.
If you move a light closer, and you make it bigger in relation to your subject. Move it farther away, and you make it relatively smaller, and therefore more narrow.
Think about The sun is over 100 times the diameter of the earth. But, at 93 million miles away, it takes up a very small portion of the sky and hence casts very hard light when falling directly on a subject at high noon.
Here is Your Tip: When photographing people indoors by available light, move your lamps closer to them, or move them close to the light source for more flattering light.
