LUT is the short form of «Look Up Table» and is basically a preset which can change the color settings of photos and videos. Usually they are used for video footage, but by using Photoshop, you can also apply LUTS to your images.

A Look Up Table, or LUT, is essentially a digital file that transforms the color and tone of your image. It essential can convert colors and details in a source file to a new destination state. For example, you can use a LUT to convert a modern digital photo to the color and tone of an older film stock. Or perhaps to convert between a color image to an aged black and white treatment.
A LUT essentially transforms tone and color based upon settings chosen by the creator of the LUT. Each RGB combination of color has a new value assigned.

The preset aperture mechanism — a click-stopped ring to set the stop-down aperture accompanied by a stopless ring that smoothly moves between wide open and the aperture preset on the other ring — has several advantages for digital cameras:
– Digital cameras generally can’t automatically stop-down a manual lens when you press the shutter button, so they behave exactly like the film bodies that were expected to be behind preset lenses.

– I’ll often preset the aperture at the smallest aperture that will not degrade the image quality by diffraction or sharply-imaging dust, then just use the stopless ring to vary within the acceptable range.

– The stopless ring allows changing the aperture during videos without steps or click noises.
