What is a hologram?
Hologram is an image registered with use of coherent laser light. It allows to preserve the 3-D information of a holographed subject. With a single source of white light, the image is "played back" and appears in 3-D exactly as it was registered in the studio. Image can project deep inside, or "stick" out of the picture.
What is the use of holograms?
They are used for attractive product packaging, security applications (they are almost impossible to counterfeit), fancy gifts, etc.. Holograms are new media of 3-D art, registration of priceless artifacts, etc.. They are also used in new technology aircraft, automobiles, etc.. A few leading companies work on holographic video and TV systems.
Can I make a hologram using my favorite photograph?
Yes, and no. It is possible to make a hologram of photograph, but photograph itself contains flat, 2-D image information. Therefore on the hologram it will also look flat. It would look just like a flat photograph floating in the space on front, or behind the frame. The third, missing dimension of a photograph cannot be reconstructed by holographic process.
What media are used for holography?
There are different
kinds of holograms:
Some holograms show motion. How is it done?
There are a few
techniques of hologram making:
What is the best way to display hologram?
Transmission holograms need light behind them, therefore home displaying is rather tricky with transmission holograms. Reflection holograms require single light source from front-above, more-less 45 degrees. These are much easier to display, and are suitable as home decor. Usually light creating strong shadow contrast is the best, and soft, or multi-source light will blur the image. Most conveinent is to display holograms at eye level, so they can be visible from a distance without a problem.
Can I afford a hologram made specially for my order ?
The main problem with custom work used to be the price. Normal pricing for custom hologram usually goes in thousands of Dollars. Just recently we developed the way of making special orders the inexpensive way. We call it "econo-custom holography". We are proud to offer film holograms at just a fraction of regular cost, on the same time offering the highest quality. For more info look at our "custom production" page.
Can the image be enlarged or reduced?
It is possible, but very complex and expensive. For this reason the natural choice is to create holograms in 1:1 size. Some stereograms can be made in other sizes.
How about full color holography?
Most of holograms
is made in one color - similar to black and white holography. The typical
greenish - yellow color of a hologram is natural color of the film -more
precisely it is "side effect" of developing process.
Will a hologram last long?
Holograms are very durable, and with proper care will outlive any regular photographs or prints.
Do I need a special lighting to view hologram at home?
Most of today's holograms are white light holograms. You would need just a regular source of light, like a track light, halogen spot or clear light bulb shining directly on the picture.
