Flash Frame -2.: A flash frame is also used to describe the first few overexposed, brighter frames at the beginning or the end of a shot, due to the camera needing time to reach speed. These can often be hard to see while editing, but are much more noticeable in a final print.

Today Dupe - A dupe is a positive copy of a positive. A dupe can also be a negative copy of a negative. A dupe is a print made in the reversal process. It can sometimes be clearer to call something a dupe, because to simply say “positive print” you could just mean a positive copy of a negative, which would not be a dupe

He has directed over 35 shorts and documentaries, including the award winning “Marlboro House”, which took top prize at the 2006 Slamdance short competition.
Today Extension Tubes - These are a handy way to turn any long lens into a macro lens for ultra-close shooting. They are hollow metal tubes that are mounted between the camera and the lens. Typically they come in a set of different lengths which can be combined. It is a good idea to open up the lens a little when using an extension tube, as a little light is lost. It should be noted that they do not work when used with wide lenses.

Lens Flare

He has directed over 35 shorts and documentaries, including the award winning “Marlboro House”, which took top prize at the 2006 Slamdance short competition.
Today: – Flare - This has two meanings: 1.: When using film on a daylight spool, the erratic pattern of raw light that washes out the beginning and end of the roll are known as “the flares.” 2.: A flare of the other kind is a Lens Flare. It is caused when light strikes the lens and either causes the entire image to be fogged in appearance, or for a little row of polygons (the silhouette of the iris) to appear from the light hitting the surfaces of the many elements in the lens. It is solved by flagging the lens.

Filter - A tinted glass or small tinted plastic sheet placed in front of the lens or behind the lens in a filter holder, used to change the color rendition of the entire shot. Filters are used to convert tungsten balanced film for use in daylight or vice versa. The can also be used for aesthetic reasons, such as a red filter to darken the sky when filming in black and white.

Today: – Foot Candle - Measurement of light. One foot candle is the light of one candle, one foot away. Many light meters will use foot candles as a starting number, which then must be converted into an f-stop based on the sensitivity of the film you are using. (Because of the great variety of different film speeds it is sometimes ambiguous to talk too much about foot candles, since a given number of foot candles will not yield the same f-stop from one film speed to another.)

Today: Extra Fade
A transition from a shot to black where the image gradually becomes darker is a Fade Out; or from black where the image gradually becomes brighter is a Fade In. Fades are done at the lab in the printing phase, but prepared by the negative cutter, who cuts in an overlap of black into the A&B rolls. Labs will only do fades in fixed amounts, such as 24 frames, 48 frames, etc.

Today: Sound Fill
Filler, Fill or Sound Fill - Filler is scrap film, most often used to keep a sound track running the same length as the picture, even though there is just silence. When used this way in can also be called sound fill. Filler is usually a print with the emulsion scraped off the center all the way along, perhaps to prevent bootlegging, but also useful in that a mark can be seen on both sides through this wide scratch.
