I was meeting with a potential doula client, and while chatting, we got onto the topic of photography, and how I am practicing with my DSLR in an attempt to start doing birth photography alongside my doula practice.

The client asked if I'd be willing to take some maternity shots for her, since she just moved to the area and hadn't had time to set anything else up with a professional, and doesn't have a big budget.

I agreed, making sure she understood I was an amateur, and so the shoot is coming up this weekend!

I'm a little nervous I'm going to totally disappoint her, and I'm looking for tips! Any advice on lighting, poses, editing, etc?

Here are some of the details: I have a Nikon D5200 with the standard 18-55mm lens, and an f1.8 50mm lens. I have an external flash and a lens hood. The client wants to be indoors, "scantily clad" and have photos that are "silhouette-y, muted, profile." (Her words.)

Any advice? Links to tips?

ETA: I'll be using Lightroom for editing.
