What is a reflex viewing system?
It's a system that allows you to look through the actual lens while shooting, usually involving a mirror to flips down in front of the sensor/film to reflect the light from the lens to an optical viewfinder with a ground glass when you want to see the image and then flips out of the way to let the light pass through the lens onto the sensor/film.
How many pixels are in a full-frame 35mm sensor?
Depends on how many the manufacturer put in there.
What is the exposure for 24fps/30fps/60fps?
The only way this would make sense is if the question was -- for example -- what was the exposure time when using a 180 degree shutter at 24 fps (the answer would be 1/48th of a second). Otherwise, how could it make any sense? If you are shooting a movie at 24 fps, do you expect the exposure to be the same whether you are shooting in sunlight or by candlelight?
What’s the toe in the linear response curve?
What’s the shoulder in the linear response curve?
How can there be a curve with a shoulder or a toe if the response is linear, i.e. not curved???
Why do we shoot a chip chart?
As a frame of reference with measurable values usually.
Do wide angle lenses have more DOF than telephoto?
No, they just appear to. Keep in mind you said "wide angle" lenses, not shorter focal lengths. Whether a focal length gives you a wide-angle view or not depends on the size of the sensor/film format.
WHY DOES A WIDE ANGLE LENS APPEAR TO HAVE MORE Depth Of Field?
Because the distorted perspective makes distant objects recede in size faster and when a background detail is smaller, it is harder to tell if it is in focus or not.
HOW DO YOU USE A Depth Of Field CHART?
They are self-explanatory when you look at one -- you input f-stop and focus distance, plus factors like focal length, format, etc. and it tells you the depth of field -- the range from near to far in which objects will look acceptably sharp.
HOW DO YOU SET FOCUS WITH A MEASURING TAPE?
You're seriously asking how to use a measuring tape to measure distance?
WHAT IS A CROP FACTOR?
The image projected by a lens (which is a circle) is cropped by the shape and size of the sensor/film and smaller sensors/film formats will crop that lens image more. So if you decide that your base reference is the image projected by a 50mm lens onto a Full-Frame 35mm sensor (8-perf 35mm horizontal still film), which is 36mm wide, then when you put that lens onto a smaller format (let's say Super-35 cine / APS-C, roughly 24mm wide) you can calculate the crop factor between the two formats (in this case 1.5X is the crop factor between 36mm and 24mm wide formats, if you are just measuring the horizontal.) This figure can be used to calculate the focal lengths for smaller formats that you need to use to get the equivalent view of certain focal lengths on larger formats.
WHAT ARE ND FILTERS?
Neutral Density filters.
HOW DO YOU COMPENSATE FOR N3 N6 N9?
ND.30 is a 1-stop loss, ND.60 is a 2-stop loss, ND.90 is a 3-stop loss.
what is OPEN FACED LIGHt?
Usually a tungsten light with just a bare globe in a reflector dish, no lens of any sort in front like a fresnel.
A net material that cuts output in front of a light by a 1/2-stop (single) or full stop (double). Scrims are usually made of metal wire when dropped right in front of a light, or fabric when used on frames farther from a light.
HOW MANY AMPS DOES A 2K LIGHT PULL?
Depends on the country and line-loss, but the math is W = V x A. So W ÷ V = A. In the U.S. a household outlet is usually 120V so 2000 ÷ 120 = 16.67A.
Now that I've answered all that, my question to you is why didn't you just Google this information???
