T stops
A more accurate measurement of light entering a lens than "f" numbers. Whereas "f" numbers represent the ratio between measured diameter and focal length, "t" stops are based on actual light transmission at different diameters.
The polarizing filter may be thought of as a screen, with an optical grid or slots, that stops all light that is not vibrating in a plane parallel to the axis of the grid lines.
Also can be explained as numerical expression of the relative aperture of a lens at its different stops; equal to the focal length divided by the effective aperture of the lens opening and written in various forms, such as f/8, f8, 1: 8, etc.
If we ignore the brightest pixels in Image B (the ones that received eight stops of light) and look at the pixels that are left, we have the situation shown in Image C. The brightest pixels that are left received seven stops of light.
This infographic by oBizMedia shows the different stops designers make in their quest to find the perfect ingredients for their work, and what the current design trends are for those designers.
The folks at Singh-Ray have created the Vari-ND, a variable neutral density filter that allows you to go anywhere between two and eight stops in a continuous range of densities by simply rotating the filter.
No rest stops or hotels either! When you consider how many earlier attempts simply exploded like Apollo 1 and killed Grissom, White and Chaffee two years before you start to appreciate why only American men have ever made it to the moon.
To see the depth of field on an SLR-type camera, you press a depth of field preview button that stops down the aperture to the one that will be used to take the photo.
Modern DSLR's typically can capture up to eight stops. Sounds great but the reality is that much of the far-end shadow detail will be obscured by excessive noise, even at low ISO settings.
In this episode, Mark explains what stops are and how they are used to adjust exposure settings on your camera.

Number 5: Look - go through magazines and find a picture that stops you dead in your tracks. Ask yourself why this occurred and use the info in your next photo outing. Transferring what works is a great way to apply something new.
-Automatic aperture - lens aperture mechanism that stops down to s preset size just as the shutter is fired, afterwards returning to the maximum aperture again for focusing and composing the next image.
Lenses were bench-tested individually for actual light transmission and assigned T stops accordingly (The T in T-stop stands for transmission),[2] but modern cinematographic lenses now usually tend to be factory-calibrated in T-stops.
Spill kill
An attachment on a Mains Flash unit (when using a brolly) that stops the spill of light to the sides and possibly indirectly onto the subject.

i take macro and wide angle pictures found out to take the clearest macro shots is wait till the light stops flashing. then take your shot and zoom in for close up cropping it will be clear.

Be prepared to take the photograph when your subject stops their movement, if even for a moment. Anticipate that instant and take the photograph at the right time.

(1) an automatic feeding system where material is fed from a continuous roll, synchronized to a stop motion arrangement that stops movement for printing; (2) a type of printing press that feeds the substrate from a bulk roll or bolt.

Second, avoid anything glossy or shiny. Shininess looks wet and greasy in photos. Third, blend, blend, and then blend some more. A high quality, tack sharp 8×10 print will show where a cosmetic product stops and starts, so blend everything in a lot.
The ability to switch the aperture and speed together was only retained on some cameras' lens barrels having the two rings side by side and with equidistant stops, such that the two rings can easily be turned together if and when desired.
This implies that the brightest stop uses up half of the 255 available tones and this is where human vision is least sensitive. There are only a few tones left to describe the darkest stops, where human vision is more sensitive.
see the ground, but, once again, the range of light is too great for the sensor, so it is now clipped off on the highlight side (right). The dark-side graph value is not clipped; instead the graph extends right to the left dark-side edge but stops ...
