...Anyhow, I understand exactly what you mean about most photographers focusing on jumps and tunnels. I wish I had more contact or weave shots.
I found this comment interesting and had to think about it for a while. As a
sometimes serious photographer (long story), I have a guess as to
why there seem to be more photos of jumps and tunnels. Bear in mind, I have never shot a dog show, so I base my thoughts on videos of shows and conversations I've read here.
Both jumps and tunnels force the dog into
specific points that the photographer can more easily prepare for.
Between obstacles is much more iffy because of missed cues, level of dog/handler training, etc., it's harder to anticipate where the dog will be. (Remember, the photographer is limited to the space of his viewfinder). I would
assume that the average photographer (not a dog person perhaps) would view the A-Frame and the Dog Walk (obstacle terms correct?) as less dramatic shots (from a photographer's point of view). Weaves would present a myriad of issues for a shooter looking for a prized shot.
These are just my opinions looking at things from a photographer's point of view and not as a dog person. I'm glad that this conversation came up because, moving forward, I can keep this all in mind when I start attending dog trials.
