Description: The Volcano Glossary by the expert and adventurer John Seach is a great place to look up terms related to volcanoes. John Seach traveled over the past 20 years to the world’s most exciting volcanoes, and witnessed eruptions during trips to more than 100 volcanoes.
The glossary is part of Seach’s website “Volcano Live”, “which monitors worldwide volcanic activity, and provides adventure tours to the world’s most exciting volcanoes. Volcano Live is the world’s only company working exclusively in volcano film and television production.”
Example term: Pyroclastic Flows/Ash Flow
Pyroclastic Flows and Nuée ardentes are the most dangerous of all the volcanic eruption styles. Pyroclastic flows are clouds of hot gas, ash, and clasts which move down hill under the action of gravity. They can move at speeds of 100 km per hour and destroy everything in their path. Mt Pelee produced a pyroclastic flow in 1902 which killed 29 000 people. Pyroclastic flows can be caused by column collapse, lava dome collapse, or boiling over of a vent like a pot of rice. Pyroclastic flows are driven by gravity and are channeled into valleys.
Distances travelled. Up to 100 km.
Speed of flows. 900 km/hr.
Temperature. 600-1100 deg C.
Pyroclastic flows are different to a Nuée ardente.

Description: This small collection of terms related to photography is found on the website of The Cleveland Museum of Art, being additional information for their outstanding past exhibition “Legacy of Light: Master Photographs from the Cleveland Museum of Art”, the first major exhibition to focus on the museum’s distinguished photography collection. So what makes this small glossary special is its focus on historical terms. And when checking out the glossary, why not having a look to the interesting and enlightening documentation of this exhibition.
Please note, the navigation of this glossary is a bit odd. With the given URL you will reach a term list, where the terms are NOT clickable. Please click the letter introducing each group. This link will bring you the actual definitions.
Example Term: Calotype
Photography’s first successful negative/positive process, allowing many positive prints to be produced from a single negative. First, high-quality writing paper, made light-sensitive with potassium iodide and silver nitrate solutions, was exposed through an aperture in a camera to light reflected off the desired subject. The latent image became visible when it was developed in gallic acid and silver nitrate. It was then fixed with hyposulfite of soda and rinsed. The resulting paper negative, or calotype, was placed in a hinged, wooden frame and contact-printed in daylight on another piece of light-sensitive paper. When the print had developed out to the desired tonality, the process was chemically stopped and fixed.
The calotype process was patented in 1841 by British photographer William Henry Fox Talbot (1800-1877). The term comes from the Greek kalos (beautiful). Usually reddish-brown or purplish in color, photographs from calotype negatives are characterized by broad effects of light and shadow because the texture of the paper prevents sharp details. Waxing the paper negative, a further refinement, yielded results much closer to the wet collodion process. The average exposure time was a few minutes or longer, varying according to the lighting conditions and size of the picture, which could range from tiny to mammoth proportions.

Description: The PhotoNotes.org dictionary is the most accurate, useful and comprehensive reference source offering contemporary photographic terms I found on the Net so far. On several occasions the descriptions go beyond mere definitions: they include the theoretical background of the term or summarize historical concepts in photography. Where suitable they give practical examples as a way of explanation. The author NK Guy took care that digital and film photography found equal coverage in his work.
To make it short: A great dictionary for everyone interested in photography from the beginner to the experienced professional.
Example Term: Parallax focussing
Also “reticle focussing.” This is a focussing technique which relies on a ground glass which has a reticle – a small mark, such as crosshairs, etched or engraved onto its surface.
This mark is used as a focussing aid, particularly for macro work. The photographer looks at the mark and moves his or her eye. If the reticle appears stationary then the subject is deemed to be in focus. The technique exploits parallax differences, and really needs a magnifier attachment to be effective.
cf. parallax, reticle.

Example term: money market account
A savings account which shares some of the characteristics of a money market fund. Like other savings accounts, money market accounts are insured by the Federal government. Money market accounts offer many of the same services as checking accounts although transactions may be somewhat more limited. These accounts are usually managed by banks or brokerages, and can be a convenient place to store money that is to be used for upcoming investments or has been received from the sale of recent investments. They are very safe and highly liquid investments, but offer a lower interest rate than most other investments.

Glossaire du théâtre By André G. Bourassa.
Approximately some 400 entries covering theater history from the early beginnings up to our time. Slight Canadian focus.
My French knowledge is not good enough to evaluate in depth French dictionaries and glossaries. But in this case I have no doubts. I studied theater many years ago in Vienna and it is clear to see that this glossary is a fine collection of relevant words. An additional sign for the seriousness of the author is the attached bibliography done in the best academic manner.
