Professionally, I’ve shot one wedding before and it was a complete nightmare. I was somewhat roped into it by a coworker at the last minute and I ended up shooting the whole thing with a Nikon D200, a Nikon SB600 flash, a Nikon SB800 flash and the wretched Nikkor 18-200 VR zoom lens. I had very little experience on the equipment, zero experience shooting a wedding and zero room for failure. Although the pictures were mostly acceptable from an artistic perspective, I would never put myself in that sort of situation again.
The flowergirl was a ham.
