Let there be LIGHT!
One of the first things I usually do in the morning is find the light! I go around the house from room to room & pull up the shades. I'm constantly chasing after Jackson so it's easy to just turn on my camera (phone) & snap away when i see a cute photo. The light is already there. I don't have to worry about using my flash which is a big no no especially when it comes to your iPhone. Natural light is so so much more pleasing :) Turn off your house lights as well. No flash, no artificial light. Let the SunShine in! :)
