Good friends of ours are getting married on a tight budget. They cannot afford to pay a photographer and have asked me if I would take their pictures. Of course I am happy to help, but I'm feeling the pressure since these are their wedding pictures! All of the photos will be taken in a room with incandescent lights dimmed moderately. I have a Nikon D3100 and recently purchased the Nikon 35mm f/1.8G AF-S DX Lens. I only have the flash that came with the camera. With all of that said, would you share with me any tips and tricks you might have to get the most from what I have, especially for the posed photos of the couple and family etc? I've read some ideas such as putting scotch tape over the flash to diffuse it, or and index card to 'bounce' the light up. Thanks in advance for any tips!
