As a photographer who primarily uses natural light, indoor lighting can be tricky. A north facing window is best but not always available in homes. In my home the best area of light coming in with a workable space is facing east. I typically use this room for my children's indoor portraits. My daughter's love to play dress-up, so I decided that we all could "play" on one hot afternoon indoors where it's cool! I wanted to use the window as back light instead of the usual even lighting I typically use. To do this I had to ignore the flashing blinkies on my histogram and use a high ISO. I'm not one to always like blown whites and high grain but I believe as an artist you need to try new things and break "rules" sometimes.
Can you tell I'm bribing with candy here? She's a typical 2 year old and wasn't happy with me at the time.
My girls have a very strong bond, I love to watch them interact!
