Tag Image File Format. A high fidelity computer file format for handling digital images that does not sacrifice colour and form detail in the way that 'lossy' compression formats such as GIF, JPEG and PNG do. [8] TLR: Twin-lens reflex. A camera with two lenses, one for taking pictures and one for viewing the scene.
In photography, stopping down refers to increasing the numerical f-stop number (for example, going from f / 2 to f / 4), which decreases the size (diameter) of the aperture of a lens, resulting in reducing the amount of light entering the iris of a lens. [1] [2]: 112 Reducing the aperture size increases the depth of field of the image.
Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
On photographs taken using a digital camera, very small highlights may frequently appear to have chromatic aberration where in fact the effect is because the highlight image is too small to stimulate all three color pixels, and so is recorded with an incorrect color. This may not occur with all types of digital camera sensor.
An apochromat, or apochromatic lens (apo), is a photographic or other lens that has better correction of chromatic and spherical aberration than the much more common achromat lenses. The prefix apo- comes from the Greek preposition ἀπό- , meaning free from or away from.
In photography, backscatter (also called near-camera reflection [1]) is an optical phenomenon resulting in typically circular artifacts on an image, due to the camera's flash being reflected from unfocused motes of dust, water droplets, or other particles in the air or water.

For example, for handheld use of a 35 mm camera with a 50 mm normal lens, the closest shutter speed is 1 ⁄ 60 s (closest to "50"), while for a 200 mm lens it is recommended not to choose shutter speeds below 1 ⁄ 200 s. This rule can be augmented with knowledge of the intended application for the photograph, an image intended for significant ...
