I bet you do. I've never had the luxury of being paid for photography, so getting 'the shot' isn't time-limited. If I was shooting an event or something, I'd be more inclined to go for broke and hope that I've more suitable shots than I intended to get.When I get paid for shooting I get trigger happy using my latest and greatest Nikon or Sony and spend boooring hours in front of the computer postprocessing.
Thank you these are all helpful. And thankyou for all the other replys i know the d3000is getting on, its shutter count is only 1500 im happy with that and dont wanna spend millions as our holiday is nearly 5k for the 4weeks excluding spends and extras.As others have said, Talk Photography is good source of info but as/when you get the camera, take the kit out and use it to get used it to it. Find yourself a scene to photograph and take the same image at differing focal lengths and apertures but keep the ISO constant i.e. 400 ISO - 18mm f2.8, 18mm f8, 18mm f16 and the repeat at 35mm and 55mm - I'd do the same for 70 - 300 as well and compare the pictures on the pc.
If you need software, download/install FastStone Image Viewer, it'll let you view and do some basic editing to the images if you want.
As a general rule of thumb, especially if you're hand holding the camera, keep your shutter speed above your focal length, so if you're shooting at 55mm above 1/60th, 200mm above 1/200th.
