Stained Glass Windows
Stained glass windows can make wonderfully colorful and exotic pictures for your travel album, and they're simple to photograph.

 


Stained glass, whether in windows or other forms, can be challenging to photograph. There may be a great distance between the stained glass and the photographer-this can be an obstacle to getting clear pictures.

Tinted glass, gelatin or plastic discs, squares or rectangles that modify the light passing through them.

Frosted glass used as a viewing mechanism in cameras without prisms. The glass is placed so that the lens projects the image against the glass for focusing and composition purposes.

Uncoated glass filters are very tough and easy to clean. The right tools are a $1 microfiber cloth or poisonous laboratory methyl alcohol, but if you're out in the middle of nowhere, Windex, or soap and water in a motel sink, work fine on plain glass.

Does frosted glass give the same effect as frosted window foil?

A multi sided glass prism housed in the roof of an single-lens reflex camera so that the image that's seen be the lens can be viewed through an optical viewfinder above the lens.

-Filters - colored glass, gelatin or plastic disks, which modify the light passing through them, mainly in terms of color content. They can be used at the camera or printing stages.

In some cases, the copyboard of the camera is a bed with a hinged glass cover.

Using color-dyed or interference-layered glass inserted into the optical path to restrict the passage of full-spectrum wavelengths. 2.

It uses ED glass and is incredibly sharp all the way to edges, and even at large stops (I have found it to be incredibly sharp even wide open, and have read at least one test report that showed it to achieve maximum LPM at f5.

Lens coating: Normal uncoated glass reflects about 5% of the light at each glass-air boundary.

We may not be carrying window-sized glass plates, but you and I also hesitate before taking a picture. We're always doing a mental calculation "is it worth it?" Subconsciously we're running down a checklist of costs, times, effort, and so on.

Glass with ED properties indicating special rare earth glass or special formulated glass that limiting or correcting of light rays passing through the lens elements to achieve all spectrum of colours to falls on the same plane of focus - especially ...

I know that if a stained glass window consists of rich hues and the rest of the building is well illuminated by ambient light, balancing the exposure of the two extremes becomes easier.

8 Carl Zeiss, $1479, (effective 202.5mm), a fast medium telephoto lens with 3 ED glass elements to compensate for chromatic aberration; this is a good lens for photographing indoor sports since the f/1.

Making a lens element is not as simple as just having a piece of founded glass. That's just the beginning.

First, he described a "variation" of the Sabatier procedure in which an exposed glass plate is given a rather short development and, without rinsing, exposed to daylight through the glass side of the plate.

When we look at stained glass, we tend to turn spontaneously toward the brightest light and our eyes have the capacity to accommodate to the disparity between the highlights and more subdued areas.

You can easily tell a coated glass surface from an uncoated one. An uncoated piece of glass reflects a lot of light, and reflected white light is also white.

Glass, Plexiglas, Non-glared Glass or No Glass
The choices are endless. When it comes to shooting our work, though, nothing beats a painting without any protection on it. Glass of any kind can get in the way of a good photograph.

These filters are made from special colored glass. Most types of glass will allow long wave UV to pass, but absorb all the other UV wavelengths, usually from about 350nm and below.

Triangular-shaped glass or other transparent material. When light is passed through a prism, its wavelengths refracts into a rainbow of colours.

The film base is polyester, which has replaced glass and celluloid. Polyester is flexible but very dimensionally stable (menaing it doesn't expand or contract much with moisture and temperature changes).

Jeff snapped a number of images through his closed glass sliding door with his Panasonic FZ15. He's kindly agreed to allow his images to be used as a tip.
Here's one of his first images.

This Coca-Cola bottle does away with the aging look of contoured glass and replaces it with a minimalist design on a glossy red canvas, worn by a smooth aluminum bottle free of contours.

There is a pentaprism in there, a five sided mirrored glass element that turns the light right side up and not backwards by reflecting the light with the camera mirror and the pentaprism.

Illumination from the lens axis using light reflected from a partially mirrored glass angled 45 degrees in front of the lens. Used primarily for medical and scientific recording where access or shadows are a problem. Also see: Ring Flash.

A tempered glass outer layer provides a wide viewing angle and resistance to scratches, and new grips on both the front and back of the camera body offer improved handling, making this the ideal pocket camera for enthusiasts.

This is an extremely small housing and has a newly designed glass wide port that measures only six inches but will accommodate all of the Nikon wide lenses. This makes for very easy packing and reduced weight. It’s great for one-hand shooting.

Anyone who’s tried this knows that completely removing grease or oil from a coated glass surface is not easy, even with the right stuff.

One example of transmitted light is colored glass. Another example is backlit, semitransparent objects such as a flower. As in the case of reflection, transmission is also tied to the process of absorption.

As detailed in the Macro (close-up) photography column (Dec'97/Jan'98), Diopters are a convenient screw on lens for close-up photos, not just a piece of tinted glass. They normally come in sets of 3 different powered lenses, +1, +2 and +4 power.

If your camera is threaded, then it's easy. Buy a gelatin filter holder and some step-up rings, or buy a threaded glass filter (expensive!). If your camera is not threaded, then you'll have to be creative.

ED - "ED" refers to "Extra Low Dispersion" glass made by Nikon for some of its lenses. It ensures apochromatic-like performance, with high contrast and sharper images. An ED lens is one that has ED glass in one or more of its elements.

Have you ever been in an museum, art gallery or cathedral and wished you could shoot some pictures of their interiors? I was once in the Vatican in Rome and I was mesmerized by the sweeping ceilings, majestic interiors, stained glass and ancient ...
