Getting the right lighting is essential to a great photograph. Even if you're just practising on your phone or a point-and-shoot before you commit to getting a single-lens reflex (AKA SLR or DSLR, the D stands for digital). Before you start trying to learn indoor lighting, first you have to understand the basics!
Whether you're snapping a selfie, taking pictures of a friend, or even getting a photo of your pet, you need to understand the most flattering lighting. Outdoor portraits are best done on slightly cloudy days. You don't want the sky to be too dark, but a little cloud cover is perfect. The reason for this is because the light is diffused.

As a professional model, I have to support my people, of course. Many models just starting out will not ask you to pay them with money. They need to build their portfolios and the
Outdoor lighting can be very fun to play with. You can get beautiful backlighting and silhouettes, in addition to the typical portraits you see, but the instructions for those are a topic for a different day. So have fun and play around!
