For a pinhole-to-film distance of 1 inch (25.4 mm), this works out to a pinhole of 0.185 mm in diameter. For f = 50 mm the optimal diameter is 0.259 mm. The equivalent f-stop value is f /193. The depth of field is basically infinite, but this does not mean that no optical blurring occurs.
Tenkiller Ferry Lake, also known as Lake Tenkiller, was named after the Tenkillers, a prominent Cherokee family who owned the land in the area. [6] The park was added to the Oklahoma State Park System in 1953, when the Oklahoma Tourism and Recreation Department (ORTD) leased land adjacent to the Tenkiller Ferry Project from the U. S. Army Corps of Engineers (USACE).
The geometry of a pinhole camera. Note: the x 1 x 2 x 3 coordinate system in the figure is left-handed, that is the direction of the OZ axis is in reverse to the system the reader may be used to. The geometry related to the mapping of a pinhole camera is illustrated in the figure. The figure contains the following basic objects:
Fees are waived for honorably discharged veterans and Oklahoma residents age 62 & older and their spouses. Passes good for three days or a week are also available; annual passes good at all 22 state parks charging fees are offered at a cost of $75 for out-of-state visitors or $60 for Oklahoma residents. The 22 parks are: [7]
This is a list of rivers in the state of Oklahoma, listed by drainage basin, alphabetically, and by size. In mean flow of water per second, the Arkansas is Oklahoma's largest river, followed by the Red River and the Neosho River .
In photographic optics, the Zeiss formula is a supposed formula for computing a circle of confusion (CoC) criterion for depth of field (DoF) calculations. The formula is c = d / 1730 {\displaystyle c=d/1730} , where d {\displaystyle d} is the diagonal measure of a camera format, film, sensor, or print, and c {\displaystyle c} the maximum ...
The following is a list of lakes in Oklahoma located entirely (or partially, as in the case of Lake Texoma) in the state. Swimming, fishing, and/or boating are permitted in some of these lakes, but not all. Oklahoma has more than 200 lakes created by dams. All lakes listed are man-made. Oklahoma's only natural lakes are oxbow and playa lakes ...
The reservoir is impounded by Robert S. Kerr Lock and Dam at river mile 336.2 (km 541.1) on the Arkansas River, just a few miles below its confluence with the Canadian River. The lock and dam are part of the McClellan-Kerr Arkansas River Navigation System , which provides for barge navigation on the Arkansas River and some of its tributaries.
