I'm beginning to want to shoot more 16mm film lately and I'm curious if my light meter is set-up correctly and a couple questions regarding some features. I've currently got a 400ft roll of 500T, so my settings are: 500 ASA, 25fps, 180 shutter. Why is it
Carrying three film lights around can be a drag, but if you understand the principles of three point lighting you can use natural light and reflectors to get the same effect. You could use a window as a key light, with a folding reflector, white wall, or a sheet of styrofoam instead ...

One micrometer is equal to 0.001 millimeter; the symbol for a micrometer is µm. "Calibrating" your microscope is simply the process of comparing your yard-stick's units to the predetermined units on a special slide. Borrow the stage micrometer slide, if possible; you probably won't ...
PROBLEM TO BE SOLVED: To solve the problem of a method for measuring the thickness of a film growing in a deposition system using the light from a tungsten lamp light source as a film thickness measuring light that the film thickness of a high grade film, e.g. a multilayer film, can ...
A photographic lighting system for use with a camera provides fill light from the direction of the camera to alleviate shadows in a photographic image obtained by the camera. The photographic lighting system includes an incident light sensor for sensing the incident light intensity on a subject to...
The Al serves as the bridge between the n-type (TiO2) and p-type (rGO) materials with a work function of 4.08 eV. The deposition of TiO2 on rGO formed a composite thin film that generates two pn-junctions, with a depletion region formed between both materials. The incident light from ...
aAfter shooting the standard exposure using the meter’s incident light settings, manually open the lens aperture to shoot one shot at +3EV over the one used for the standard exposure. Then close the lens aperture down to take one shot -3EV under the one used for standard exposure. 在射...
A new mode of cavity ring-down measurements in which an incoherent, broadband light emitting diode (LED) is used as the spectroscopic source is described. Light from a pulsed LED (570 nm, 12 nm FWHM) was coupled into a 32 cm linear optical resonator and a ring-down waveform obtained on...
An improved light emitting diode for a photosensor which enables correction of a change in the amount of light from a light emitting element (LED) in accordance with a change in ambient temperature is disclosed. The light emitting diode for a photosensor includes a substrate (12) and a light...
