There are 2 times a day that photographers refer to as the "golden hour." They are shortly after sunrise or before sunset when the daylight is softer than when the sun is higher in the sky. ALL THINGS LOOK STUNNING IN THE GOLDEN HOUR. ALL! Whatever you do, stay away from photographing yourself at high noon because that is when the sun is the harshest and is creates hard shadows. This is not good in my world. Sun streaming through your windows at home can be quite beautiful. Start watching it now. Every evening I look forward to watching the setting sun at home to see if I can capture an interesting photo. It is exciting to me and being that we live where the sun can be elusive, we take full advantage of it when we see it. Which brings me to my next point, when the sun doesn't shine.
Since I live in the Pacific Northwest, I can write a few books about what to do when the sun doesn't shine. You quickly learn
that life goes on anyway. While it can be cumbersome taking photos in the pouring rain, it need not be necessary unless one has the proper equipment to ensure ones professional camera does not get damaged. What we can do is think about planning a session on an overcast day which is actually ideal lighting for a portrait. It's basically mother natures studio in action. The lighting is easy on the skin and eyes and allows one to relax and not have to worry about the sun. Start studying that type of lighting right now and see what you think. It truly is equivalent to being in a professional studio with equipment that is designed after the temperature of natural light.
