The Human Eye’s Subjective View of Color

Elements of a good photo include composition, color, and brightness. One of your jobs as a photographer is to capture the colors you see as intentionally as possible. Whether you intend to show the color exactly as you see it or you want to enhance the color by adjusting the color temperature, it is your job to understand your choices and intentionally compose your picture.

Understanding Digital Zoom

The digital zoom feature offered by some camera models does not really zoom in closer to the subject. Digital zoom crops into the center area of the captured frame, effectively enlarging the pixels. This results in a picture with a lower overall image quality. If you don’t have a telephoto or optical zoom lens and you want a close-up, physically move closer to the subject, if you can.

Digital Point-and-Shoot

This is a lightweight digital camera, aptly named after the two steps required of the photographer to capture an image. Basically, point-and-shoot cameras require pointing the camera and taking the picture without manually adjusting settings such as the aperture, shutter speed, focus, and other settings that professional photographers routinely set on more sophisticated cameras.

Digital Single-Lens Reflex (DSLR)

This camera is named for the reflexing mirror that allows you to frame the image through the lens prior to capturing the image. As light passes through the DSLR camera’s lens, it falls onto a reflexing mirror and then passes through a prism to the viewfinder. The viewfinder image corresponds to the actual image area. When the picture is taken, the mirror reflexes, or moves up and out of the way, allowing the open shutter to expose the digital image sensor, which captures the image. Most features on a DSLR are adjustable, allowing for greater control over the captured image. Most DSLR cameras also allow the use of interchangeable lenses, meaning you can swap lenses of different  focal lengths on the same camera  body.
