The Fifth Salon of Photographs A/thoughthe announcementof the Fifth PhotographicSa/on pub/ished by AmericanBirds was bur•ed in sma// •/pe on the /ast page of the Februaryissue, 45 entries were received. And a/thoughthe overa//qua/i•/ did not appear to be quiteas high as in recentyears, enough exce//ent prints were received to give us an exhibit that is both varied and interesting. Last year, we remarked, not in a// seriousness,that perhaps pictures of photogenic birds such as herons shou/d be handicapped. Thisyear our words seem to have had impact, because of a// the entries received, on/y two were of herons, and none were of Snowy Egrets, possib/y the candidate for the highest handicap of a//. The six judges this year inc/uded members of the staffs of American Birds and AUDUBON Once again, photographs were exhibited with no informationabout them visib/e, judges were g•ven ba//ots and asked to se/ect their first five choices in order. Points were awarded those photographs se/ected on a descending order from 5 to 1. Unfortunate/y,neither the first nor the second prize photographsare of a shape that is adapt- ab/e to our cover dimensions.And so, breakingan ancientone-year-o/d tradition of using the f•rst prize winneras our Augustcover, we have chosen to use instead the photographthat was a c/ose third.

THE PENTAX DIGITAL CAMERA FLASH LIGHTING SYSTEM An exploration of the functioning and practical operations for the Pentax Camera Brand Dedicated Flash Lighting System. This Guide includes the principles for Camera Operations, Built-in flash, Pentax and Dedicated Third Party flash units. Nigel McGregor - © 2015, London, United Kingdom The Pentax Digital Camera Flash Lighting System – © Nigel McGregor 2015 Title (i) The Pentax Digital Camera Flash Lighting System Welcome To My Guide I’m Nigel McGregor, a passionate user of Pentax DSLR photography equipment. A New Zealander, but long term resident of the United Kingdom, where I live to the South of London near the Surrey border. Landscapes, gardens, flowers and architecture are my main photographic interests, but like many family photographers it is the portraits and action shots of loved ones that take up the most SD card space on my camera. It was the striving to get better results with these people shots, often indoors, that has propelled my interest in flash photography with Pentax equipment. I love taking flash pictures with my Pentax camera and flash. Even more so wirelessly with a softbox or umbrella set-up. But getting good consistent results can be frustrating, and so I want to share my thoughts on understanding the Pentax flash system, and how to get the most out of it. Take a look at the Contents and Introduction here to give you a quick idea of what is contained in this guide. Please join in the discussions about the guide and flash photography in general on the forums. I’d love to hear your feedback, suggestions and responses to the contents of this guide!

HONEYWELL PENTAX Cameras and Accessories
H O N E Y WELL PHOTOGRAPHIC PROD U C T S -J HONEYWELL PENTAX cameras and accessories HONEYWELL PENTAX SPOTMATIC with behind-the-Iens exposure systeJll The world's first single-lens-reflex camera with a behind-the-Iens exposure system, the Spotmatic is the crowning achievement of the Honeywell Pentax line. Absolute correct exposures are simple with the Spotmatic. Its two CdS sensors read light from the image focused on the ground glass the same amount of light that strikes the film plane. With any focal length lens, or with bellows, extension Honeywell Pentax Spotmatic, chrome finish, tubes, or filters proper exposure is automatic and extremely with filA Super-Takumar lens. accurate. The Spotmatic's metering system can be operated with one hand without taking the eye from the viewfinder by simply pushing a switch and centering a needle. And, for special effects, it's simple to change shutter speed or aperture for over- or under exposures. The same size and classic design as the famous Pentax H3v, the Spotmatic also features: eye-level pentaprism finder with Fresnel lens; central microprism and positive grid focusing; instant-return mirror; focal plane shutter; speeds from 1 to 1/ 1000 sec., plus Bulb on single non-rotating knob; ASA-Range from 20 to 1600; self timer; auto-reset counter; ratchet film-advance lever cocks shutter and advances counter; FP and X flash terminals, and threaded lens mount.

Honeywell/Pentax Spotmatic SP II CLA Tutorial by Eugene Pate https://learncamerarepair.com/ https://www.facebook.com/groups/360490091319202/ Post #1 https://www.facebook.com/groups/360490091319202/?post_id=585244602177082 Upon initial testing the shutter speeds are out of tolerance and the exposure meter isn't working properly. The camera looks well used but no damage and internally disregarding the dust it's been well taken care of with no signs of corrosion except for the pesky battery cover and that's the result of its close proximity to the mercury battery. Light seals and cushions will have to be replaced after cleaning and lubricating. Post #2 https://www.facebook.com/groups/360490091319202/?post_id=585245582176984 As in previous Spotmatic posts I start by removing the rewind knob and reminder dial parts. Note the ball bearing that acts as a "detent" pointed out in the photos, I use a magnetic driver tip to lift it out of its hole and set it aside so it doesn't get lost.

Shuttering methods and the artifacts they produce Henry Dietz and Paul Eberhart; Department of Electrical and Computer Engineering, University of Kentucky; Lexington, Kentucky Abstract When exposure times were measured in minutes, the open- ing and closing of the shutter was essentially instantaneous. As more sensitive films and brighter optics became available, expo- sure times decreased, the travel time of the shutter mechanism be- came increasingly significant, and artifacts became visible. Per- haps the best-known shutter artifacts are the spatio-temporal dis- tortions associated with photographing moving subjects using a Figure 1. Still image from high speed video of leaf shutter focal-plane shutter or sequential electronic sampling of pixels (electronic rolling shutter). However, the shutter mechanism also can cause banding with flickering light sources and strange ar- tifacts in out-of-focus regions (bokeh); it can even impact res- all pixels during the same time interval – thus causing specific olution. This paper experimentally evaluates and discusses the types of artifacts. artifacts caused by leaf, focal plane, electronic first curtain, and The aperture value, Av, represents the rate of light transmis- fully electronic sequential-readout shuttering. sion through the lens.

The grey cloud is low, and the rain is steady, but the muted light is just perfect for the subject matter all around me, namely waves lapping around the artfully sculpted blocks of ice on the black sand. Now I’ve seen many images of this unique combination before – it’s an Icelandic photographic staple – but there’s no resisting the appeal of such stark, elemental beauty. In fact it’s a beauty that is enhanced by the flat lighting, a cold scene of black and blue with simple graphic appeal. But as so often is the case here in Iceland the conditions are difficult: apart from the rain, salty spray is being driven inshore off the waves and onto my increasingly crusty camera, lens and filter. So be it, such adversity is now familiar. -

Lens Mount and Flange Focal Distance
This is a page of data on the lens flange distance and image coverage of various stills and movie lens systems. It aims to provide information on the viability of adapting lenses from one system to another. Video/Movie format-lens coverage: [caveat: While you might suppose lenses made for a particular camera or gate/sensor size might be optimised for that system (ie so the circle of cover fits the gate, maximising the effective aperture and sharpness, and minimising light spill and lack of contrast... however it seems to be seldom the case, as lots of other factors contribute to lens design (to the point when sometimes a lens for one system is simply sold as suitable for another (eg large format lenses with M42 mounts for SLR's! and SLR lenses for half frame). Specialist lenses (most movie and specifically professional movie lenses) however do seem to adhere to good design practice, but what is optimal at any point in time has varied with film stocks and aspect ratios! ] 1932: 8mm picture area is 4.8×3.5mm (approx 4.5x3.3mm useable), aspect ratio close to 1.33 and image circle of ø5.94mm. 1965: super8 picture area is 5.79×4.01mm, aspect ratio close to 1.44 and image circle of ø7.043mm. 2011: Ultra Pan8 picture area is 10.52×3.75mm, aspect ratio 2.8 and image circle of ø11.2mm (minimum). 1923: standard 16mm picture area is 10.26×7.49mm, aspect ratio close to 1.37 and image circle of ø12.7mm. -
