Lighting
Lighting
is the single biggest determinant of how your camera needs to be set.
With only a few exceptions, you can never have too much light. Use this
slider to experiment with different indoor and outdoor lighting conditions.
Distance Use
this slider to simulate how close or far you are in relation to the
subject.
Focal
length
Moving
this slider is the same as zooming in and out with your lens. A wide,
zoomed out setting creates the greatest depth of field (more things
are in focus) while zooming in creates a shallower depth-of-field (typically
just the subject will be in focus).
Mode
The
exposure modes of an SLR let you control one setting while the camera
automatically adjusts the others. In Shutter Priority mode, you to set
the shutter speed while the camera sets the aperture/f-stop. In Aperture
Priority mode, you set the aperture/f-stop while the camera sets the
shutter speed. Manual mode is fully manualyoure on your
own! Refer to the cameras light meter to help get the proper exposure.
Although every real SLR camera has a "fully automatic" mode,
there is not one herewhats the fun in that?
ISO
ISO
refers to how sensitive the film will be to the incoming
light when the picture is snapped. High ISO settings allow for faster
shutter speeds in low light but introduce grain into the image. Low
ISO settings produce the cleanest image but require lots of light. Generally,
you will want to use the lowest ISO setting that your lighting will
allow.
Aperture
Aperture,
or f-stop, refers to how big the hole will be for the light to pass
through when the shutter is open and the picture is snapped. Lower f
numbers correspond with larger holes. The important thing to remember
is this: the higher the f number, the more things in front of and behind
the subject will be in focus, but the more light you will need. The
lower the f number, the more things in front of and behind the subject
will be out of focus, and the less light you will need.
Shutter
speed
Shutter
speed is how long the shutter needs to be open, allowing light into
the camera, to properly expose the image. Fast shutter speeds allow
you to freeze the action in a photo, but require lots of
light. Slower shutter speeds allow for shooting with less light but
can cause motion blur in the image.
