Techniques Glossary Lens coating
Transparent coated on lens elements that helps reduce reflections and flare to improve image contrast.
Nano Particle Coating is used not only in projection lenses in IC steppers and scanners, but is also in interchangeable camera lenses as a "Nano Crystal Coating".
Coating - A technique where chemicals are introduced to lens resulting in reduction of flares and reflections, therefore produces balanced-lit photography outputs.
Coating
(see Multicoating)
Colour balance
How a particular colour film reproduces the colours of a scene. All Colour films are formulated to be exposed by light of a certain colour quality (daylight or tungsten).
Coating or not?
Nearly all lenses sold today for 35mm SLRs are multicoated to reduce internal reflections. This is pretty critical for image quality - particularly contrast and flare.
coating pigments
mineral materials used for coating paper stock such as clay, (the most common), talc, calcium carbonate, titanium dioxide, and zinc oxide.
Coating against reflections between lens groups Edit
Modern lenses are coated with a very thin layer of antireflective material (like magnesium fluoride or calcium fluoride).
Lens Coating A layer or multiple layers of thin, anti-reflective materials applied to the surface of lens elements to reduce light reflection and increase the amount of transmitted light.
Blade Coating: A paper coating method which results in a very smooth surface.
Blanket: A fabric coated with natural or synthetic rubber which is clamped around the blanket cylinder and which transfers the ink from the press plate to the paper.

The ITO coating issue is not a major one, but it is a real one. You could likely clean your sensor with regular Eclipse a fair number of times before having any problems and perhaps not even then.
Multilayer coating
The depositing of multiple coats of anti-reflective materials on a lens surface to reduce ghost images and flare produced by internal reflections and insure faithful colour rendition.
Resin - coating plastic coating applied to both sides of paper
Glossy - shiny
Matte - not shiny ...
As you can see, coatings and optical glass have a hardness in the 450-600 range. This is pretty hard, harder than most metals for example.
SUPER SPECTRA COATING or SST - Canon's multi-layer coating applied to most of its FD lenses.
Their goal: A coating process that combined high-performance optical parameters, ease of cleaning, and extreme resistance to scratching and abrasion.
Antireflection coating
One or more thin layers of refractive material ( often magnesium fluoride ) coated upon the surface of a lens to minimize surface reflection. It is deposited on the lens by vaporization of the metal in vacuum.
-Backing - dark coating, normally on the back of a film, but sometimes between emulsion and base, to reduce halation. The backing dye disappears during processing.
Archival (in the context of prints) is a term with no definite scientific meaning but is generally used to describe an item that will retain its original properties over a long period of time Baryta Baryta papers have a multi-layer coating ...
ANTICURL BACKING-A transparent, gelatin coating sometimes applied to the opposite side of a photographic film from the emulsion to prevent curling by balancing the forces that tend to curl the film, as it is wet and dried during processing.
Gold is used as a coating enabling biological material to be viewed under a scanning electron microscope.
Cast coated papers have a coating that hardens in contact with a polished chrome surface that gives it an exceptionally glossy finish.
I am not sure what type of AR coatings are put on camera lenses, but many are quite durable and resistant to many solvents (we use isopropanol, methanol, acetone, toluene, sometimes even dish washing detergent).
I hadn't realized it, but a change in the coatings for many popular laptop brands has made a huge difference in the brightness and overall readability of many LCDs.
The lens features Super Electronic Beam Coating (EBC), the original coating system of Fujinon that keeps ghosting and flare to a minimum to promise optimal picture quality.
Extra high grade tape coatings are generally superior in noise immunity and lower in dropouts. This means that you get a better recording, and you'll get a better second and third generation copy.
Phosphorescent coatings rapidly absorb and store light, then slowly release it. Though commonly used to complement spooky Halloween decorations, clock and watch faces often sport phosphorescent coatings so they can be easily read at night.
Lustre coating is also available to add more sheen and durability to prints. And with prices that catch nearly anyone's eye ($1.99 for an 8x10) Mpix is taking no prisoners.
The light is redirected in all directions via either the translucent coating (when using the “cloud' cover) or through ridges etched in the plastic sides of the Clear version.
Fiber paper does not have the resin coating. This means that it takes longer to wash (see fiber processing). Not all, but many fiber papers available today are near or full exhibition grade.
This is especially true of P&S cameras because they often don't have the same level of multi coating on their lenses as SLR cameras do; multi coating, ...
The light-sensitive coating on a piece of film, paper, or printing plate. When making prints or copies, it's important to know which side is the emulsion side so that the image can be exposed in the correct orientation (not reversed).
Wiping results in scratches in the coatings or glass.
Do not clean optics with ammonia or other cleaners not specifically designed for the purpose of lens cleaning.
Next, inspect the front element by tilting it an angle, so a strong light reflects from it, revealing the lens coating. Look for a consistent finish and no marks scratches, swirls, or places where the coating has disappeared.
Dichroic
A vapor-deposited coating (usually on glass or metal) that reflects unwanted portions of the light spectrum. A filter with such a coating, typically one that converts tungsten light to match daylight sources or films.
With digital cameras it is especially important to buy filters with non-reflective coating, because otherwise light reflected from the sensor can bounce back onto it, causing ghosting.
In addition, there are many options, drawn from classical printmaking for enhancing or coating prints after printing-bleaches or stains, paints or pastels, metallic leafs or appliqués, oils or polymers, varnishes or encaustics.
This serves as the base for the same iodized collodion coating and silver nitrate bath used in the ambrotype process. First made in 1856, millions were produced well into the twentieth century.
And whoever heard of a coating on a lens making it self-cleaning under UV light? What a remarkable discovery! I'd rush right out and patent it, but I don't think that anyone at the patent office would take me seriously.
Resin Coated Paper: Photographic paper that has thin coating of plastic resin on the backside of the paper and in between the emulsion and paper support.
Graininess A term particular to film, it refers to the appearance of grain (the structure of a film's coating or emulsion) in a print, transparency or negative.
Similarly, there are different coatings on different lenses. Some coatings are there to help fight reflection while others account for things like UV blocking.
Different coating quality and front element diameters may be the reason for this. Usually these differences are small but it can be as extreme as 1 EV (1 f-stop). Due to TTL metering this is no problem except maybe for flash photography.
After the iodine and silver reacted to form a coating of silver iodide, the plate was placed into a light-proof bag and transferred into the back of a camera.
You can use the old film photographer's trick of applying a thin coating of anti-scratch fluid or petroleum jelly to the slide before copying it; this will "hide" most scratches.

What is more, almost all camera lenses have a very thin coating on the outermost lens that can be lost if you wipe it with anything other than very smooth materials.
The actual emulsion, the light sensitive coating that makes film work, is basically the same in both formats.
This line of filters has a 5+1 layering system on each side of the glass: 5 layers of anti-reflective coating and a transparent easy-clean top coat, making the filters 12 layer ones.
You can purchase Vignetting filters or you can smear a thin coating of Vaseline around the edges of a UV filter. By Vignetting you create a frame in your photograph which makes your subject the center of interest.
The front element of your lens and the beautiful multi coating on it, that you paid a fortune for and have lovingly looked after, are not being used. The quality of your photo is now, to some extent at least, in the hands of your close-up lens.
If you're one of those photographers, you should use a multicoated UV filter, which helps curb any additional image degradation, or flare, that you might otherwise get from the sun or reflective light sources. Multicoating can ensure that 99.
Film is a gelatin acetate that is coated with light-sensitive metal halide crystals that when exposed to light transform and re-align themselves to "preserve" the image in the coating.
