Pentax Super Program and Cosmicar A 28/2.8. The corners are dark from the hood I used, which I normally use on a Pentax DA35/2.4 on APS-C. I just recently bought this camera and lens, the film was included with the lot, Fujicolor 200. The film is not dated it could be pretty old. It is color film but I thought a black and white conversion would be natural.

As for this midsommar festival. In the depths of Elva. With thunderstorms, and you guessed it - acid
It seemed the years of aimless wandering and hard work had come to fruitition. This was to become a year of rest. Of bliss.
The Fulbright Program honored their 2019-2020 Top Producing Institutions and 2018-2019 HBCU Institutional Leaders with an event featuring remarks by ECA Principal Deputy Assistant Secretary Matthew Lussenhop, Deputy Assistant Secretary for Academics Caroline Casagrande, Robert Jones (Chancellor, University of Illinois at Urbana-Champaign), Cynthia Jackson-Hammond (President, Central State University), and Johnathan Holifield (Executive Director of the White House Initiative on Historically Black Colleges and Universities).
So here's how it works:
> Turning the aperture ring raises the "Diaphragm Bar" behind the lens. At f/2.8 it's completely below the lens opening, and at f/22 it's just below the lens centerline.
> When the mirror rises, it drags this panel up with it; the odd shaped hole in the middle is the shutter opening. The mirror/shutter rises just as fast as its spring can whack it, and returns at the same speed as soon as it reaches the top.
> At f/2.8, the shutter is open for the entire distance of travel shown in green above - it takes about 1/60 second to cover this distance. But at f/22, with the DIaphragm Bar up where the purple line indicates, the shutter doesn't open until it reaches that line, and it closes as soon as it passes that line on the way down. The entire movement takes the same time as before, but the open time is only the time that it takes to travel the distance shown by the purple arrows. Assuming that the speed at f/2.8 was 1/60, this works out to about 1/500 second.
> The aperture at f/22 (and at all other settings except for f/2.8) is in the shape of a triangle with its point at the top - the top 2 sides are the edges of the "roof" part of the shutter opening, and the bottom side is provided by the Diaphragm bar.
It's actually just a little more complicated than this. In the above description, the f/22 opening is not centered on the same axis as the f/2.8 opening, and in fact if the Diaphragm Bar actually went as high as the purple line it would block off the center of the lens. So, in addition to all of the above, at the smaller apertures, the mirror/shutter is actually stopping its upward travel earlier than it does at full aperture. How does it do this? In the view of the Diaphragm Bar at www.flickr.com/photos/rick_oleson/53225547915/in/dateposted/, there is a second, gold colored bar that's coupled to the Diaphragm Bar, with a bent-up tab at its tip. As the Diaphragm Bar rises, this gold bar comes down - the tab at the end is the stop that the mirror strikes against to stop its upward travel. The two bars are coupled together so that the mirror's stopping position produces a centered triangular aperture opening at all settings. Dang.
Whoever did this will probably never be famous - but he was good.
