Igor was asking about why I'd use the BFF (Really Big Flash) setup, rather than simply the AF540.
Here is a photo of my flash setup for the group performance: http://www.flickr.com/photos/ellarsee/5262376648/in/set-72157625475180697/ The near flash is in the middle of the back wall. I'm not sure of the exact dimensions of the dance floor, but it's likely about 40x80 feet. In the corner of the room, you can see the spot that they used (with a pink gel) to highlight some of the dancers. I had both cameras with me during the performance, and I'd shift between the K-x with the 16-50 ISO 6400 wide open and the K20 with my 18-250 at (in this case f/9) at ISO 100. K-x (cropped at 29 mm) http://www.flickr.com/photos/ellarsee/5261765035/in/set-72157625475180697/ K20 (also at 29mm) http://www.flickr.com/photos/ellarsee/5262373116/in/set-72157625475180697/ You can see, how even on the back half of the floor, inverse square is really biting me with the dancers closer to the light close to overexposed, while the ones in the back of the room are just about right. In this case, I'm guessing that the nearest dancers are probably 20' from the closest light, and 50' from the furthest. -- Larry Colen [email protected] sent from i4est -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
