I was back over at her house tonight. She confirmed I shot with the lights off. I do understand flash photography but was trying to shut out the ambient backlight in this case to create a different look. I chose upping the SS whereas I should have chosen aperture instead. Per another group, they said the lines were due to the way I had the shutter set. I have now changed it to mechanical shutter. I agree, I shouldn't have used that high of SS, but I had never seen that before. The light is fine. I was using my AD200 which is fine for indoors. It did great on the normal photos where I wasn't trying to block the backlight. Thanks for the explanation and I will check out the videos.
