The Fade

Mark A. Cella is a distinguished fellow of film studies at California State University in Los Angeles. He’s a published writer on Cinema History and Film Theory. 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: 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.

Emulsion Type

Mark A. Cella is a distinguished fellow of film studies at California State University in Los Angeles. He’s a published writer on Cinema History and Film Theory. 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: Emulsion Type Part 1 -

A film’s emulsion type refers to the composition of its emulsion, whether it was manufactured to be fast, slow, grainy, fine-grained, colorful, pastel, black and white or color, daylight balanced, tungsten balanced, etc. The emulsion type is represented by a number. For Kodak it is a series of four numbers, such as 7248. The “72” always stands for 16mm camera stock, and the same emulsion type is found in 35mm as 5248, “52” being the designation of 35mm.

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.

Mark Cella's Emulsion Batch

Mark A. Cella is a distinguished fellow of film studies at California State University in Los Angeles. He’s a published writer on Cinema History and Film Theory. 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: Emulsion Batch

Emulsion Batch - The emulsion batch is the series of numbers on the film can the come after the Emulsion Type. When the film is made, each batch is given a number so that you can shoot a single sequence with one particular batch. Just as a suit where the pants and jacket were cut from different bolts of fabric might be a little off, a sequence shot with different emulsion batches might also be a little off. From one sequence to the next, of course, this doesn’t matter. (And the batches themselves have become more consistent in recent years, so mixing them is less of a sin nowadays.)

The are photographed onto the film in its manufacture, and are there to aid the negative cutter in lining up shots in the process of conforming the negative. They are sometimes called latent edge numbers to distinguish them from inked-on code numbers. 2.: Code Numbers are sometimes called edge numbers.

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.

There are, if you're in a reductionist state of mind, only two types of people in the world: dog people and cat people. Dog people – I count myself among their ranks – will enjoy Frankel's adaptation of journalist John Grogan's bestselling account of life, love, deadlines, and death with the "world's worst dog," a yellow Labrador retriever named Marley.

It corresponds to the moduations of the sound. The projector reads the track by passing it between the exciter lamp a light-sensitive photo-electric cell which generates a voltage that is amplified and fed into a speaker

How Deep Is Your Field?

Mark A. Cella is a distinguished fellow of film studies at Fresno State University. He’s a published writer on Cinema History and Film Theory. He has directed over 35 shorts and documentaries, including the award winning “Marlboro House”, which took top prize at the 2004 Slamdance short competition.

Today’s Topic: Depth Of Field

Depth of Field - While a lens focuses on a single plane of depth, there is usually an additional area in focus behind and in front of that plane. This is depth of field. Depth of field increases as the iris is closed. There is more depth of field the wider the lens and less the longer the lens. There is a deeper area in focus the further away a lens is focused than there is when a lens is focused close. Depth of field does not spread out evenly; the entire area is about 1/3rd in front and 2/3rds behind the plane of focus. To factor together all these variables it is best to consult a depth of field table, such as the ones found in the American Cinematographer’s Manual.
