Does shooting digital differ from film? I can't seem to capture (pan) my dogs as they run. User error, of course, as I use a camera infrquently. Any advice, settings, etc.? Of course, not much sun in Alaska these days.
Thanks.

Hi Jan,
Have a look into the tutorial below, they can be helpful for you:

Aperture and Shutter Priority Mode:
---------------------------------------------------
Usually on the dial on top of your digital camera. On Olympus digital cameras, the mode may be represented by A/S/M. On Nikon digital cameras, shutter priority mode is symbolized with an S and aperture priority mode is an A. On Canon digital cameras, generally shutter priority is represented by Tv (strange, I know) and aperture priority is Av. Other digital camera manufactures generally use some sort of similar lettering.

What it does: Let’s get really basic, to make sure we are all on the same page. Any photograph has both an aperture and a shutter speed. The aperture regulates how wide the lens opening is, while the shutter speed regulates how long the shutter was left open. These two items, in tandem, regulate the exposure of a photograph.

In an automatic mode, the digital camera chooses its own combination of aperture and shutter speed to create a good exposure - you don’t have to do any of the thinking. But sometimes, you want more control over your digital camera, and that’s when shutter and aperture priority come into play.

These two modes allow you to wrest control of either of the two variables away from your digital camera. In shutter priority, you control the shutter speed while the camera determines the aperture. This allows you - with sufficient lighting conditions - to set a shutter speed fast enough to freeze sports action or slow enough to create a motion blur.

Aperture priority mode allows you control over the depth of field of an image. The more open the lens is, the more shallow the depth of field is. Generally, for portrait photography large apertures are used so as to create a silky-smooth background behind a person kept in sharp focus. Conversely, in landscape photography small apertures are used to keep as much of the scene sharp as possible.


What to worry about: Using higher aperture numbers requires more light in a scene for a proper exposure. If you set your aperture to a higher number - f/8 or f/10, for example - the camera may need to choose a really long shutter speed to ensure a proper exposure. If your hands are shaky and if you aren’t using a tripod, this could result in a blurred photo. Similarly, your digital camera may not have a low-enough aperture number to support very fast shutter speeds - 1/800 or 1/2000 of a second, for example. If that’s the case, either the digital camera will refuse to take the picture or your photo will be underexposed.

Thanks,

Excellent! Thanks, Andy. This explains the blurred photos. Insufficient light and an unsteady hand.

Appreciate your time.
