To me, lighting is the most important factor in your photography. As a newborn photographer, I also think it is one of the hardest to learn. It is also something that is hard to teach on the internet. I know for me it is still a work in progress. Not only do you need to know how to meter for light but you need to know how to see it. When you walk in a client’s home you should be able to scan the light in the different rooms and see, in your head, what your images will look like. It definitely takes practice… lots of practice. I think this is where we on-location photographers have an advantage. We are forced to shoot in different lighting situations at every session. Every home is different, even the same home has different light at different times of the day. A good way to start to see light is experiment in your own home with different rooms and different times of the day.
