Case Study—A Part Opaque and Part Transclucent Material
The mineral we are photographing here has a part that's rocklike and a part that's translucent crystal. It's almost as if we're photographing two separate subjects.
The Assignment ...
OPAQUE - (1) Does not transmit light. (2) Coloring used in photography to render parts of a negative opaque.
OPAQUE BODIES - Objects that permit no light to pass through them, but reflect light.
Opaque
Not transparent, among other meanings including to 'block out' a specific area of an image or film.
Opacity ...
opaque edge (safe edge)
the edge of a sheet of photoscreen stencil film that has been covered with opaque tape or other opaque instrument, where during exposure develops and washes out with the design portions of the stencil, ...
Opaque - not capable of transmitting light
Refraction - bending of a ray of light in its passage between optical media of different densities
Over exposure - the result of too much light being permitted to act on a sensitive material ...
Opaque
An object or material that does not transmit light. Also, a dense client.
Opaque tube, either cylindrical, square of funnel shaped, use to shield a lens from stray light outside the field of view.
Lens speed: ...
Opaque areas: These areas are not transparent. Therefore, the only thing that is seen is whatever is on this layer. The lower layers are not seen at all.
Opaque liquid is a dense red or black pigment, dissolved in water to form a liquid paint used to fill in film areas that are required to pint as pure white.
An opaque curtain containing a slit that moves directly across in front of the film in a camera and allows image-forming light to strike the film.
Focus ...
The opaque #87 from Tiffen (I'd get it here) and Kodak Wratten gel (I'd get it here) is probably the most common filter used for IR photography. The RM72/R72 from Hoya (I'd get it here) and 87C / 093 from B+W (I'd get it here) and others are similar.
A soft, almost opaque browning effect mostly associated with prints from the early years of photography. Some digicams have a sepia mode, and the effect can be created with many photo-editing software.
Shooting Modes ...
A card or other opaque object is held between the enlarger lens and the photographic paper in such a way as to block light from the portion of the scene to be lightened.
"find some semi opaque material to place over you lens"
Did you mean "your flash"?
-Lens hood - opaque tube, either cylindrical, square of funnel shaped, use to shield a lens from stray light outside the field of view.
-Lens shade - see Lens hood.
-Lens shutter camera - camera with the shutter built into the lens.
Changing bag
Opaque fabric bag, which is light tight and inside sensitive materials may be handled safely.

Objects that are relatively flat and opaque may be successfully printed using cyanotype photography.
Special-purpose filters for black-and-white film may be colorless, contain a hint of color, be noticeably colored, or almost visually opaque. Some special- purpose filters can be used with both black-and-white and color film.
1800: Thomas Wedgwood makes "sun pictures" by placing opaque objects on leather treated with silver nitrate; resulting images deteriorated rapidly, however, if displayed under light stronger than from candles.
On interference filters the clear aperture is often delimited by an annulus of metal or opaque material. CG-5 A style of GEM made by Celestron.
With your safelight off place a sheet of unexposed paper on your baseboard then place a small opaque object, a coin is usually favourite, on the paper then turn on the safelighting for about seven minutes, ...
With a DSLR, you’ll need a tripod because exposures will be long, even in bright sun, and an opaque infrared filter such as a Hoya R72 or B+W 092. Compose before putting the filter in place, then position the filter and take the picture.
By painting on the layer mask, you can make parts of the layer opaque or transparent: painting with black makes the layer transparent, painting with white makes the layer opaque and painting with shades of gray makes the layer semi-transparent.
To create silhouettes, simply put an opaque object in front of a bright background and expose for the background.
Make sure you use opaque board- not another piece of photo paper! You need to completely mask the light. Also, orient the board so that the dark and light areas will be on each strip.
Pop the timer to make a 2-second exposure.
Traditional darkroom operators used to hold various shapes made of metal or other opaque materials over the print on the end of long wires in order to temporarily block the light.
If high-contrast film is used for making the negative and positive transparencies that are sandwiched together, the sandwich is almost completely opaque, and little or no image appears on the final print.
One useful trick is to cover the end of the telescope with a piece of cardboard or similar opaque that has two round holes cut into it. When you look through the viewfinder at a bright object you'll see two dim ghost images.
Even though they might appear gray or even opaque to our eyes, this isn't how your photo will appear; the camera's metering automatically compensates by letting in more light.
Like everything else on the GXR the Direct Screen can be customized - though in this case the only option is how opaque it is (you get three options: light, dark and 'picture off', which gets rid of the preview image altogether).
This means the texture layer is sitting on top of the background, and that it's opaque, so that you can't see anything underneath it. You can make the texture layer partially transparent by selecting another Blending mode.
Focal plane shutters comprise two opaque curtains. The first curtain blocks the light path. During exposure it moves out of the way to be followed by a second curtain which covers the exposed film or CCD.
This is a special filter made of either glass or mylar coated with a virtually opaque layer of aluminum. A solar filter cuts down sunlight by 99.9999%. It transmits only about 1/1000th of one percent of the light.
By default, the layer with the white paint (Layer 1) is 100% opaque, i.e. we cannot see through the white paint to the picture underneath. Click on the Opacity drop-down and slide the the lever left and right until the effect looks just right to you.
Photograms: Photographs made without a camera by placing opaque objects on a sheet of photographic paper, exposing to light and processing. Photograms have dark backgrounds and white silhouettes of the opaque objects.
Last time around, we showed how backlighting can define the shape of a portrait subject -or any opaque object-by etching a bright white highlight, called a rimlight, around its outer edges.
Diffuser
A piece of opaque plastic that sits over the top of a flashgun. It's job is to soften the light from the flashgun, and therefore reduces harsh shadows caused by a 'bare' flash.
Noun derived from the active verb "bokasu" which means to befog, to gradate, to render opaque, to smudge or render out of focus.
Focal-Plane Shutter An opaque curtain containing a slit that moves directly across in front of the film in a camera and allows image-forming light to strike the film.
This type of layer can be either transparent or opaque. If you have several layers open already you can chose "layer from background" to create a new layer from the original background layer.
Objects used in cyanotype photography should be flat and opaque. When using the cyanotype method, remember that the prints turn out best with greater contrast. Also, wear gloves, as the chemicals stain.

Put a few sheets of plain white paper on a table (you'll need a few sheets with ordinary copy paper because a single sheet will not be entirely opaque), and put the product on it.
Gouache (Poster Paint): A solid (opaque) water-based paint that dries to a matt finish.
Hue. The color of light that is reflected from an opaque object or transmitted through a transparent one.
Hue. Refers to the color of the image and is separate from how light or dark it is.
32-Bit Image - A digital image that utilizes 24 Bits of data for each pixel. The additional 8 bits are used to save the level of opaqueness in each pixel. The image may contain up to 16.5 million colors with 256 levels of transparency.
If it's too sunny where you're shooting, there are solutions besides waiting for a change in the weather. If there's someone available to assist you, have them hold something opaque over your subject to block direct light, and shoot in the shade.
An additional bit found in a pixel or pixel plane that indicates whether the pixel is displayed as visible (opaque) or transparent (overlayed). See alpha channel.

The backing paper is black, or at least one side of it is blackened to render it completely opaque.
For example, for auto-exposure to work, light must bounce back to a small sensor located just to the side of the internal flash. With a clear housing, no worries. But with the opaque aluminum housing, ...
(You can avoid flare by either positioning your camera so that the light doesn't shine directly into your lens, or by shading the lens with your hand or a hat or any other opaque object. Just be sure that the object is kept out of the image frame.) ...
