Sheet
built 229 days ago
Sheet film is large format and medium format photographic film supplied on individual sheets of acetate or polyester film base rather than rolls. Sheet film was initially supplied as an alternative to glass plates. The most popular size measures 4×5 inches; smaller and larger sizes including the gigantic 20×24 inches have been made and many are still available today.

The Ice Sheet opened in April of 1994. It was built at a cost of over $6 million. Funding for the Ice Sheet came from 3 sources; $3.25 million from the Utah Sports Authority, $2 million from Weber County and $1 million from Community Donations.

Sheet metal workers first study plans and specifications to determine the kind and quantity of materials they will need. They then measure, cut, bend, shape, and fasten pieces of sheet metal to make ductwork, countertops, and other custom products. In an increasing number of shops, sheet metal workers use computerized metalworking equipment. This enables them to perform their tasks more quickly and to experiment with different layouts to find the one that wastes the least material. They cut, drill, and form parts with computer-controlled saws, lasers, shears, and presses.

Sheet mulching should not be confused with composting, artificial weed barriers, or green manuring. Sheet mulching as described here is quite different from these in that it seeks to recreate the organic mulch layer of the forest with a minimum of effort from people. Properly planned, a backyard or orchard system will produce its own raw mulch in sufficient amounts and people are involved only in putting this material back onto the ground where it belongs.

Sheet films have notches cut into one short side. This makes it simple to determine which side is the emulsion, when the film is hidden from sight (in the darkroom, or inside a changing bag). When holding the sheet in "portrait" orientation (short side up), with the notches in the upper right, the emulsion side is facing the photographer. The notch patterns vary in size and layout; each type of film has its own distinct pattern, commonly referred to as a notch code, to enable film type identification.

Sheet metal workers in manufacturing plants make sheet metal parts for products such as aircraft or industrial equipment. Although some of the fabrication techniques used in large-scale manufacturing are similar to those used in smaller shops, the work may be highly automated and repetitive. Sheet metal workers doing such work may be responsible for reprogramming the computer control systems of the equipment they operate.
