I recieved a Nikon D300 Digital Camera for Christmas. It is a FANTASTIC camera but I can only use the viewfinder to take a photo. I would LOVE to be able to use the display screen to take pictures. Can you help me?
Why on earth would you want to use a perfectly fine, fully adjustable camera like you would a P&S camera?
The good news is you cannot. There is no live view on that camera, so you are going to have to use it just like photographers have been using theirs for decades, looking through the viewfinder.
Just think a minute. How much camera movement (which causes blur) do you think you are going to put into your images when holding a nearly two pound camera at arm’s length?
The other point I guess I need to make is live view is really only used when the camera is attached to either a microscope or telescope and in both cases attached to an AC adapter, because those large LCD’s use up a lot of battery power. There is another time the live view is used and that is when the camera is on a tripod and is in a studio shooting products … again using an AC adapter.
You have a wholly different camera now. Forget any of the bad habits you may have learned with a P&S and start learning how shoot your fine camera the way photographers have done for decades. To learn how to do that, you may find taking a class in photography if only to learn how to hold your camera correctly (which is in your owners manual). Perhaps the only way to learn how to use a camera is to take your time. Stop using "auto" settings, "Program" settings and go right to using the camera in the manual mode and use the light meter in the viewfinder to choose your exposures and see what happens when you shoot at slow shutter speeds or with the aperture wide open.
