Photo Equipment Interesting Information
No camera, whether digital or traditional, can stand alone, needing several pieces of photo equipment to maximize its use. Photo equipment includes tripods, scanners and filters, which are the items on which we will focus. However, many other products can be considered photography equipment, such as projectors, reflectors, and lenses.
A film scanner is a piece of photo equipment used for scanning photographic film directly into a computer without the use of any intermediate printing process. This photo equipment offers many advantages over using a flatbed scanner to scan in a print of any size, such as granting the photographer direct control over cropping and aspect ratio from the original, unmolested image on film; as well as special software or hardware to remove scratches and film grain. This is important because photography equipment like film scanners are capable of very high resolutions which means that dust and scratches take on gigantic proportions. Even small specks of dust, invisible to the naked eye, can obscure a cluster of several pixels. Techniques like the median filter, frequently called despeckle in many photo editing programs, like Adobe Photoshop and the GIMP, work by examining a pixel in relation to the other pixels around it; if it differs too much it is replaced with one set to their median value.
A tripod is certainly a timeless component of photography equipment. Tripods are used to prevent camera movement. Instances that require use of this photo equipment include slow-speed exposures or when telephoto lenses are used, since any camera movement while the shutter is open will produce a blurred image. Tripods also lowers camera shake, and are therefore instrumental in achieving maximum sharpness, as well as accomplishing precise framing of the image. Tripods have evolved over time as photography equipment, and are now being made with flexible legs and different types of head, such as ball heads that provide faster and more accurate rotation; pan tilt heads with with separate axes and controls for tilting and panning; and others including gimbal heads, fluid heads, gear heads, alt-azimuth, and equatorial heads.
A filter is a photo equipment accessory that consists of an optical filter that can be inserted in the optical path. The filter can be a square or oblong shape mounted in a holder accessory, or, more frequently, a glass or plastic disk with a metal or plastic ring frame, which can be screwed in front of the lens or clipped onto the lens. These pieces of photography equipment let photographers have more control of the images being produced. Sometimes they are used to make small changes; other times the image would not be possible without the filter. Types of filters include clear and ultraviolet, color correction, color separation, contrast enhancement, infrared, neutral density, polarizing and special effects.
