What the heck is Aperture ??

mengenal aperture

In photography, the lens aperture functions like the iris of the human eye. Opening and closing to adapt changing light levels. The aperture opens wide to admit more light in low-light situations and closes down to a pinhole when the light gets bright.

With oder cameras , the photographer often had to adjust the aperture setting manually for each shot. However , modern , auto-exposure , digital cameras typically set the aperture automatically to produce the correct exposure as indicated by the cameras built in light meter. But just because we dont have to actively manipulate aperture values doesnt mean that we should ignore the aperture component of your exposures completely.

Framing and Composition

One thing some people don't think about when taking a photo is the look of the final image. Purposely framing and composing elements of the picture in the viewfinder before snapping the shot will usually result in a much better final image.Try thinking of composing the picture as seeing all the visible elements in the viewfinder as parts, and then putting them together as a pleasing whole. Consider what the viewer(s) want to see, then determine the best way to display the main subject.

Also, decide if you should hold the camera vertically or horizontally before snapping the shutter. If you are taking a photo of a single person right in front of you, it is best to hold the camera in the vertical position. If not, you will likely have too much wasted space on each side of the image. On the other hand if you are taking a group or landscape, it is usually better to hold the camera in the horizontal position. You will fill more of the frame with the main subject(s).
