I have a 400 too and cut a notch in the end of a 3 x 5 index card to fit into the 'slot' behind the head when it is turned up in the bounce position - works pretty well and takes up no room in the bag. Rockwell has a template for the 400 for a bounce sheet made out of a 8-1/2 x 11 paper and it works well too but takes up a lot of room and is pretty cumbersome.
Shot this sunset Tuesday evening and this is my first picture post and hope it meets your approval. It was shot with a Nikon D200 and a Nikkor 18-200mm zoom lens.
Have been a lurker here for a while and learned a lot so finally decided to jump in and join. Took this picture of the moon last night and hope to get another tonight. Used a Nikon D200 with a Nikkor AI 300mm f4.5 and a Nikon TC-200 converter mounted on a monopod. Shutter speed was 1/100 and aperture was f16.
