A Glossary of Photographic Terms: T
- Telephoto Lens
- A lens that makes a subject appear larger on film than does a normal lens at the same camera-to-subject distance. A telephoto lens has a longer focal length and narrower field of view than a normal lens.
- T-Grain technology
- Trademark for patented Kodak film emulsion technology used in all Kodak Advanced Photo System films; uniquely shaped grains that align better than conventional silver crystals, absorbing and transmitting light more effectively to produce sharper images. Kodak Advantix 400 film is the company's first 400-speed film using all T-grain emulsions.

- Thin Negative
- A negative that is underexposed or underdeveloped (or both). A thin negative appears less dense than a normal negative.
- Through-The-Lens Focusing
- Viewing a scene to be photographed through the same lens that admits light to the film. Through-the-lens viewing, as in a single-lens-reflex (SLR) camera, while focusing and composing a picture, eliminates parallax.
- Through-The-Lens Metering
- Meter built into the camera determines exposure for the scene by reading light that passes through the lens during picture-taking.
- Time Exposure
- A comparatively long exposure made in seconds or minutes.

- Shades of white in a finished print, controlled by the color of the paper, varying from white to buff.
- The degree of lightness or darkness in any given area of a print; also referred to as value. Cold tones (bluish) and warm tones (reddish) refer to the color of the image in both black-and-white and color photographs.
- Intensifying or changing the tone of a photographic print after processing. Solutions called toners are used to produce various shades of colors.
- A positive photographic image on film, viewed or projected by transmitted light (light shining through film).
- Transparent magnetic layer
- Information storage layer built into Advanced Photo System film that enables enhanced information exchange capabilities, improving print quality by capturing lighting and scene information and other picture-taking data; basis for future information exchange features.
- A three-legged supporting stand used to hold the camera steady. Especially useful when using slow shutter speeds and/or telephoto lenses.
- Tungsten Light
- Light from regular room lamps and ceiling fixtures, not fluorescent.
