Gallery Text That Accompanies This Exhibition In
Steeped in the classical training of an English gentleman, Edward Dodwell (1777/78– 1832) first traveled through Greece in 1801. He returned in 1805 in the company of an Italian artist, Simone Pomardi (1757–1830), and together they toured the country for fourteen months, drawing and documenting the landscape with exacting detail. They produced around a thousand illustrations, most of which are now in the collection of the Packard Humanities Institute in Los Altos, California. A selection from this rich archive is presented here for the first time in the United States. Dodwell and Pomardi frequently used a camera obscura, an optical device that made it easier to create accurate images. Beyond providing evidence for the appearance of monuments and vistas, their illustrations manifest the ideal of the picturesque that enraptured so many European travelers. The sight of ancient temples lying in ruin, or of the Greek people under Turkish rule as part of the Ottoman Empire, prompted meditation on the transience of human accomplishments. As Dodwell himself wrote: “When we contemplated the scene around us, and beheld the sites of ruined states, and kingdoms, and cities, which were once elevated to a high pitch of prosperity and renown, but which have now vanished like a dream . we could not but forcibly feel that nations perish as well as individuals.” Dodwell’s own words accompany the majority of images in this exhibition. His descriptions are drawn from his Classical and Topographical Tour through Greece, during the Years 1801, 1805, and 1806 (London, 1819). The author’s original spelling, capitalization, and punctuation have been retained. -

Depth of Field PDF Only
Depth of Field for Digital Images Robin D. Myers Better Light, Inc. In the days before digital images, before the advent of roll film, photography was accomplished with photosensitive emulsions spread on glass plates. After processing and drying the glass negative, it was contact printed onto photosensitive paper to produce the final print. The size of the final print was the same size as the negative. During this period some of the foundational work into the science of photography was performed. One of the concepts developed was the circle of confusion. Contact prints are usually small enough that they are normally viewed at a distance of approximately 250 millimeters (about 10 inches). At this distance the human eye can resolve a detail that occupies an angle of about 1 arc minute. The eye cannot see a difference between a blurred circle and a sharp edged circle that just fills this small angle at this viewing distance. The diameter of this circle is called the circle of confusion. Converting the diameter of this circle into a size measurement, we get about 0.1 millimeters. If we assume a standard print size of 8 by 10 inches (about 200 mm by 250 mm) and divide this by the circle of confusion then an 8x10 print would represent about 2000x2500 smallest discernible points. If these points are equated to their equivalence in digital pixels, then the resolution of a 8x10 print would be about 2000x2500 pixels or about 250 pixels per inch (100 pixels per centimeter). The circle of confusion used for 4x5 film has traditionally been that of a contact print viewed at the standard 250 mm viewing distance. -
Dof 4.0 – a Depth of Field Calculator
DoF 4.0 – A Depth of Field Calculator Last updated: 8-Mar-2021 Introduction When you focus a camera lens at some distance and take a photograph, the further subjects are from the focus point, the blurrier they look. Depth of field is the range of subject distances that are acceptably sharp. It varies with aperture and focal length, distance at which the lens is focused, and the circle of confusion – a measure of how much blurring is acceptable in a sharp image. The tricky part is defining what acceptable means. Sharpness is not an inherent quality as it depends heavily on the magnification at which an image is viewed. When viewed from the same distance, a smaller version of the same image will look sharper than a larger one. Similarly, an image that looks sharp as a 4x6" print may look decidedly less so at 16x20". All other things being equal, the range of in-focus distances increases with shorter lens focal lengths, smaller apertures, the farther away you focus, and the larger the circle of confusion. Conversely, longer lenses, wider apertures, closer focus, and a smaller circle of confusion make for a narrower depth of field. Sometimes focus blur is undesirable, and sometimes it’s an intentional creative choice. Either way, you need to understand depth of field to achieve predictable results. What is DoF? DoF is an advanced depth of field calculator available for both Windows and Android. What DoF Does Even if your camera has a depth of field preview button, the viewfinder image is just too small to judge critical sharpness. -

Optimo 42 - 420 A2s Distance in Meters

The width of the sharpness zone grows proportionally with the focus distance and aperture and it is inversely proportional to the focal length. In practice the depth of field limits can only be defined accurately by performing screen tests in true shooting conditions. * : data given for informaiton only.

Flash in Stereo
FLASH IN STEREO “Golf Legend Bobby Jones Taking a Swing", photo taken by Dr. Harold Edgerton , the inventor of electronic flash in 1938, using stroboscopic flash photography. A Presentation by George Themelis NSA / July 2010 Outline • Why Flash? • Flash Advantages in Stereo • Short History of Flash Photography • Flash Bulbs vs. Electronic Flash • Flash Synchronization • Flash Exposure • Issues when using flash • Special Flash Techniques • Flash in Slide Bar (Single camera) Stereo • Flash with Vintage Stereo Cameras • Flash with compact digital stereo cameras • Flash with twin cameras Why Flash? When the existing light is dim, there is a need for artificial light in order to get good expo- sures . Example: In a well-lit interior space a typical exposure using 100 ISO is f8 at 1 second. Compare this to a “sunny day” f16 1/100, 2+7 = 9 f-stops less light. Hand hold- ing the camera or taking pictures of people at these long exposures is impossible. Hence flash is a necessity for taking pictures indoors. Without extra light, the photographer has three options: 1) Open up the aperture (f-stop), 2) Increase the time of the exposure . 3) Increase sensitivity (ISO) . These methods have disadvantages & limitations: • Opening up the lens aperture reduces the depth of field (can be a problem in stereo) in- creases lens aberrations, plus there is a limit (lens maximum aperture) • Theoretically, there is no limit in increasing exposure time, but in practice 1) film recip- rocity, 2) digital noise, 3) blurry pictures without solid support, 4) subject movement. • Increased sensitivity leads to film grain or digital noise. -

Depth of Field in Photography
Instructor: N. David King Page 1 DEPTH OF FIELD IN PHOTOGRAPHY Handout for Photography Students N. David King, Instructor WWWHAT IS DDDEPTH OF FFFIELD ??? Photographers generally have to deal with one of two main optical issues for any given photograph: Motion (relative to the film plane) and Depth of Field. This handout is about Depth of Field. But what is it? Depth of Field is a major compositional tool used by photographers to direct attention to specific areas of a print or, at the other extreme, to allow the viewer’s eye to travel in focus over the entire print’s surface, as it appears to do in reality. Here are two example images. Depth of Field Examples Shallow Depth of Field Deep Depth of Field using wide aperture using small aperture and close focal distance and greater focal distance Depth of Field in PhotogPhotography:raphy: Student Handout © N. DavDavidid King 2004, Rev 2010 Instructor: N. David King Page 2 SSSURPRISE !!! The first image (the garden flowers on the left) was shot IIITTT’’’S AAALL AN ILLUSION with a wide aperture and is focused on the flower closest to the viewer. The second image (on the right) was shot with a smaller aperture and is focused on a yellow flower near the rear of that group of flowers. Though it looks as if we are really increasing the area that is in focus from the first image to the second, that apparent increase is actually an optical illusion. In the second image there is still only one plane where the lens is critically focused. -
