Mom got me a 65inch (I think) tripod along with my new D3200 for Xmas and I'm wondering if it's something I'll need. I guess it couldn't hurt when taking landscape photos. I was reading Ken Rockwell's site and he said you don't need one, etc.
What do you think?
Also, my tripod I think costs around $40. What's the difference between that and a several hundred dollar one? Build quality, etc?
First, a $40 tripod (unless you're talking something small like a gorillapod or it's used or Mom mugged a pro photographer for his tripod and then tossed two $20's on his limp body as she sauntered away, tripod in hand) is a waste of money. Tripods can do lots of things, none of them do them all perfectly and depending upon what your priorities are, that affects what type of tripod you want to get. But the one constant that must be true of a decent tripod (or better) is: it should keep your camera stable. And a $40 tripod (minus the exceptions I mentioned above) just won't do that. It will hold a camera so you can run in front and pose next to the Grand Canyon with a cheesy smile. But it won't do what a serious photographer would use a tripod for...keep it stable and level or allow you to shoot 3 second waterfall shots or 30 second astro shots or long exposures for an interior with low light.
Second, as I said, a tripod has different priorities. Do you want to be able to travel with it (so it fits in carry-on luggage)? Then it's probably legs with 4 segments (less stable) but very compact. Shooting interiors and architecture? You want a level on it. Hiking great distances? You want composite (so it's as light as possible while still being stable). Shooting food? You want a center column that can go horizontal. Shooting outdoors in rocky or uneven terrain? Than you probably want a tripod with spikes on the legs. Shooting macro? You want legs that will go wide enough that you can be inches off the ground. Are you especially tall? Then you need a long center column. Shooting sports with a 400mm zoom? Then you probably want a monopod. I could go on. But ideally, you get clear on how you'll use the tripod and then find one that meets those needs. But the one constant--it has to be rock-solid stable.
Third, what to use it for? Long exposures of water (like a waterfall). Astro photography. Interiors with low natural light. Landscapes (especially the "blue" hour). When you've got a big lens on your camera and keeping it stable is a challenge. Some wildlife photography (where you get away from the camera so the wildlife will get closer).
You don't "need" a tripod for most photographs that most amateurs do. And a clever pro can make do without a tripod (I've used a bungee cord, a bean bag, a stable rock, a door frame when a tripod wasn't an option). But if you want to shoot the stuff I mentioned above, having a tripod is invaluable. Look at it this way, you don't NEED a circular polarizer filter to shoot landscapes. But it makes landscape photos so much easier and effective and powerful. I rarely use a tripod but I always use it for certain types of photos or concepts.
As for a good one...depends upon what you're trying to shoot (see above). I have a gorillapod, a cheap REI folding triangle, a camera clamp, a bungee cord, and two Manfrotto tripods (one of which is for travel and folds down to about 12 inches). The two Manfrotto's cost me $180 and $300 respectively.
Here are a couple of examples...Beach-4 is in Oregon and is a long exposure b/c of the low light (and incredible color) after the sun has set. Estes Park-1 is a long exposure with the intention of blurring the water next to the snow and ice in the creek. Fork is a macro shot...you need a tripod to keep the camera stable as you get the precise DoF. Orchid-1...a paph macro shot (which again requires a tripod for precision). Portland dog-1...that's a panning shot that required a tripod so I got smooth blur for the runner and surroundings but a relatively sharp dog. Vernal Falls is a long exposure (I believe with a NDF during high noon in Yosemite in August). All of these shots required a tripod to make them happen.
