<p>Krista,<br /> I found this book "Understanding Flash Photography How to Shoot Great Photographs Using Electronic Flash" <a href="https://www.amazon.com/Understanding-Flash-Photography-Photographs-Electronic/dp/0817439560">https://www.amazon.com/Understanding-Flash-Photography-Photographs-Electronic/dp/0817439560</a> by Bryan Peterson to be very helpful to understand how to use flash. His book "Understanding Exposure" was also helpful. One drawback for you would be that he uses Nikon equipment. I found his explanation of how shutter speed and aperture affect ambient and flash to be useful regardless of equipment manufacturer.<br /> Hope that helps, <br /> Ray</p>
