Where is the balance though between having the camera constantly at the ready, looking for the next photo op and staying in the moment yourself? It's most prevelant with a camcorder, I see Dad's at scenic places that are seeing hardly anything except what is in the viewfinder. I think the same sort of thing can happen with the camera.
Scenario 1: You are walking down a trail and as you round the corner you see a black bear a good ways up the trail. You reach for the camera in your pocket (wait it's not in that pocket it's in the other pocket, you dig it out, look down, turn it on, woops wrong setting, change setting, okay now its on, get it up, focus it, snap pic, woops blurry, get another one, wait it saw me, there it goes.
You get home, couple years later you tell your son you saw a bear once and you have a picture of it. You get out the photo album and show them the small black blob in a fuzzy green forest picture. The remark is 'huh, cool'.
Scenario 2: You are walking down a trail and as you round the corner you see a black bear a good ways up the trail. You didn't bring a camera so you stop and watch the bear grazing on some blackberry bushes. You notice the details, oh wait look at that...it has a cub with it! Just behind it are two cubs! Wow this must be a mother bear, so cool...wait it saw me, there they go.
You get home, couple years later you tell your son you have saw a bear once, you were walking and rounded a corner, there it was. You stopped and were watching it for several minutes. It was munching on blackberry bushes, it looked huge! It was really black and had long hair. I remember thinking 'man it must get hot out here with all that fur!', then I noticed it had TWO CUBS with it! Baby bears! It was so cool. At first I was kinda nervous but as I watched it eating blackberries I remember thinking how cool it was to be standing there watching a bear in the wild. She noticed me and ran off. The remark from your son is 'wow cool, I wanna see a bear'.
(I know this is a highly fictional scenario but I think it delivers a point and is plausible).
