Contact scan of the film. Slight burning over the lights
I made thes two shots in slight differences of light because the sun was falling down. I didn't know how much wide was the angle opened by the pinhole, and my bellow didn't allow to obtain the optimal focal lenght which was 5 cm. I've been surprised from the exact coincidence of the focal of my pinhole and of the 160 mm lens.

As we prepare for the Wisconsin Idea Seminar we make gratitude bundles like this one. The Wisconsin Idea Seminar is not possible without tireless and generous collaborators across the state who spend months planning, consulting, and offering expert guidance and ideas that strengthen and enrich our collective learning. The anatomy of our gratitude: a water cloth--or towel, as it is meant to function—each unique and hand-woven by a student in the School of Human Ecology’s Design Studies. Pictured here is a water cloth woven by Marley Vogel (BA’19). In preparation for their weaving project, students participated in a First Nations Cultural Landscape tour led by Omar Poler, the American Indian Curriculum Services Coordinator in the School of Education where they were invited to contemplate notions of responsibility, reciprocity, and respect and the interconnectedness that tether us to the land and water that surrounds our campus. The course was led by associate professor Marianne Fairbanks, a Wisconsin Idea Seminar alumna. Inside the water cloth is a jar of syrup harvested in Dane County by Dan Cornelius, a member of the Oneida Nation of Wisconsin and founder of Yowela Farm in rural Stoughton.

The ring tower is a striking high-rise building in a prominent location in Vienna, where is located the headquarters of the Vienna Insurance Group. It was built in 1953-1955 after designs of Erich Boltenstern at Schottenring inside the Viennese Ringstrasse and is located at the stop Schottenring of the Wiener Linien (Vienna Public Transport). The 73 meter (93 meter height including the weather light column) high ring tower was deemed as innovative project for the reconstruction of the city.
The building, which previously stood on this plot, was the only one of the entire Scots ring which was destroyed in the Second World War. The ring tower with its 23 floors and its 20-meter high weather lighthouse is the second highest building inside Vienna's Ringstrasse. Higher is only the Gothic-style St. Stephen's Cathedral. In addition to the central office of the Vienna Insurance Group are now also offices of Wiener Stadtwerke (public utility company) in the ring tower. In the office building a total of 12,000 square meters of effective surface is available. The facade and parts of the ring tower were renovated in 1996.
Name
In a contest, a name was sought for the then very modern office skyscraper. Among 6,502 entries the name "ring tower" was chosen. There were, among other proposals, such as City House, Gutwill-house (goodwill-house), house of reciprocity, high-corner, new tower, Sonnblick-house, insurance high-rise, Vindobona-house or vision-house (farsightedness-house) of the creative population after the war. One of the submitters of the name "ring tower" was rewarded with an honorarium of 2,000 shillings.
Weather lighthouse
Weather lighthouse, seen from the ring road
On the roof there is the 20-meter high weather lighthouse with 117 lights in differently colored light signals the weather for the next day displaying (each 39 white, red and green lights as well as 2 additional air traffic control lights).
This light column is directly connected to the ZAMG (Central Institute for Meteorology and Geodynamics) on the Hohenwarte in Vienna.
Meaning of the signals:
red ascending = temperature rising
red descending = temperature falling
green ascending = weather conditions will be better
green descending = weather will be worse
Flashing red = warning lightning or storms
Flashing white = snow or ice

Since 2006, the ring tower is changed every year into an "art tower " by covering the building with printed webs. The covering consists of 30 printed network paths with about 3 meters wide and 63 or 36 meters in length , and the resulting area is approximately 4,000 square meters.

The difficulties of long exposure film are many. Wind, dark, impatience, reciprocity...etc. This was exposed under a misty moon with steady winds. Exposure is really good, but lots of little things to master yet.
I'm extremely happy with the tones in this photo.
If you read about the reciprocity of this film...it's almost unbelievable. (obviously that didn't come into play on this photograph...or any on the roll for that matter...just something to think about.)

Test exposure #2 of 2 from the new 4x5 pinhole. Actually, it's turned out surprisingly well (the first exposure failed, abysmally). Ok, so this has been a little 'shopped to remove the huge scratch on the neg (and a contrast bump), but it's pretty true to the negative. Bit of dust, but that's par for the course.
First time in a darkroom without a safelight. More disorientating that you might think, and I think there is a slight fog because there was some light leaking.
More to come (hopefully better ones)

I decided to try a long exposure with the box camera, well the darkness kinda forced me into it really. I set it up on the tripod - completely squint - it was impossible to see anything through the viewfinder so I just pointed it in the general direction of the boats. The scene metered 1/13s and using a reciprocity app on my phone I exposed for 1/45s. Seemed to work out OK, except for a mega squint horizon and a generally boring shot. I do like the movement in the boats and in particular the mooring rope as they moved during the exposure.

75mm pinhole camera,I think F166. Pleasantly pleased with how these turned out,the app pinhole assist gave good readings with reciprocity included.
Okay so I was not 100% pleased with my results for week three. The trouble using a film that I don't know what sort of reciprocity failure it has and trekking out into the cold Toronto night to do some long exposure and hop from bar to bar in the process. But actually there are a few here that I'm good with. One film to rule them all.

How will you be affected if Congress mandates concealed carry reciprocity nationwide? Chances are, your state’s gun laws will be seriously undercut and there is nothing local law enforcement could do to stop it.

The shutter will only go down to 1 second timed so anything slower requires bulb. The meter said 2 seconds would do but I stopped it down to get 8 seconds that was a compromise between being able to get it roughly timed right and avoiding reciprocity failure.

The much larger aperture available - compared to the kit zoom lens I normally use - enabled a faster shutter, a lower (less "noisy") ISO, and also a shallower depth of field.
The lighting colour was often a terrible mix of direct sunshine, blue sky and the very orange colour reflected from wooden table tops. The "colour balance" adjustment tool in a photo editor editor - selectively adjusting highlight, mid-tone and shadow colours was useful in reducing the effects of the sometimes very blue shadows. (Traditionally this type of tool is used to "fix" issues relating to colour film, where the colour of light and dark areas could vary. This is for lots of reasons for relating to the processing and chemistry of film; and also to the physics of photons exposing film grains - for example reciprocity failure en.wikipedia.org/wiki/Reciprocity_(photography) where darker areas for each of the colours present in the shadows may not be recorded proportionately. Presenting the same images in Black and White is another way of "dealing with" [avoiding!] the issue.

Finishing the roll. Shooting a Zero 2000 (eBay find) with Kodak 400TX. Except I thought I was shooting Ektar 100 (the packaging is almost identical). Turns out, this 400TX is underexposed by about a full stop after factoring in reciprocity failure. These are unaltered scans, but one stop of exposure should be a trivial post fix. Misc exposure durations, but typically in the neighborhood of 8-40 seconds.
As an American passport holder, there aren’t too many countries that require a visa. Many countries like Brazil have what is called a reciprocity fee, meaning that if the US charges Brazilian citizens a visa fee, then Brazil charges Americans the same fee but without the requirement of a visa. In entering these countries via a flight, you usually just pay the fee in the airport, and you are on your way. It is all quite simple.
Other countries like Russia require quite a bit for an American to enter their country, like a personal recommendation or request from a Russian citizen. Crazy right?! Russia is really killing my “travel to Russia” bucket list vibes. Anyway, China doesn’t go that far, but it is quite the process along with being rather expensive. The US charges a hefty fee for Chinese visas so China charges that same price for American's to enter China.... awesome.
Even still, Chinese visas aren’t exactly easy to come by in the United States. A few months prior to my Beijing flight I was told that Chinese visas were actually backed up; and, the US was not likely to issue you your visa for several weeks. This meant that the chances of getting the visa were small and even if you did get one, it might take weeks or months to come in.
It is important to note that most major Chinese cities will give you a short term visa in the airport. You cannot travel outside of the city and you cannot stay longer than 72 hours. But, if you are work within those limits, then it is a much easier visa process. Also, if you are visiting cities like Macau and Hong Kong that function outside the Chinese government, you aren't required to have a visa under 30 days. Again, you can’t travel outside of the city without a formal Chinese visa.
I was staying in Beijing a few hours past the 72 hour visa deadline due to my flight schedule so I was required to get a formal Chinese visa. Instead of taking the chance that I wouldn’t get the visa in time if I applied in the US, I opted to apply for a Chinese visa in Japan. I had read that Tokyo’s visa process was quite efficient and since traveling in and around Asia is common in Tokyo, it was much easier to get a visa there. Whenever you are traveling, you usually have the option to get the visa for another country in a different country to your origin as long as you visit the embassy for which you are trying to obtain a visa for.
Since my travels to Tokyo, the visa process has changed. You can no longer go through the Chinese Embassy. There are many conflicting reports online, but please note, you have to use the Chinese Visa Application Service Center (visaforchina.org) in Tokyo. The cost is now 9,000 YEN. Please read the website thoroughly making sure not to miss anything. For instance, Chinese and Japanese holidays are different to American holidays and the office will be closed on those days. Also, your passport cannot be expiring within 6 months or you will not be issued a Chinese visa. Read the website thoroughly, fill out the paperwork from the website in advance, have the exchange cash in YEN needed, and apply as much in advance as possible. Do your research!
HAPPY TRAVELS!

The Daasanach (also known as the Marille or Geleba) are an ethnic group inhabiting parts of Ethiopia, Kenya and Sudan. Their main homeland is in the Debub Omo Zone of the Southern Nations, Nationalities, and People's Region, adjacent to Lake Turkana. According to the 2007 national census, they number 48,067 people (or 0.07% of the total population of Ethiopia), of whom 1,481 are urban dwellers.
There are a number of variant spellings of Daasanach, including Dasenach and Dassanech (the latter used in an episode about them in the TV series Tribe). Daasanach is the primary name given in the Ethnologue language entry.
The Daasanach are also called Marille especially by their neighbours, the Turkana of Kenya. The Daasanach are traditionally pastoralists, but in recent years have become primarily agropastoral. Having lost the majority of their lands over the past fifty years or so, primarily as a result from being excluded from their traditional Kenyan lands, including on both sides of Lake Turkana, and the 'Ilemi Triangle' of Sudan, they have suffered a massive decrease in the numbers of cattle, goats and sheep. As a result, large numbers of them have moved to areas closer to the Omo River, where they attempt to grow enough crops to survive. There is much disease along the river (including tsetse, which has increased with forest and woodland development there), however, making this solution to their economic plight difficult. Like many pastoral peoples throughout this region of Africa, the Daasanach are a highly egalitarian society, with a social system involving age sets and clan lineages - both of which involve strong reciprocity relations.
The Daasanach today speak the Daasanach language. It belongs to the Cushitic branch of the Afro-Asiatic family. The language is notable for its large number of noun classes, irregular verb system, and implosive consonants. For instance, the initial D in Daasanach is implosive, sometimes written as 'D.
Modern genetic analysis of the Daasanach indicates that they are more closely related to Nilo-Saharan and Niger-Congo-speaking populations inhabiting Tanzania than they are to the Cushitic and Semitic Afro-Asiatic-speaking populations of Ethiopia. This suggests that the Daasanach were originally Nilo-Saharan speakers, sharing common origins with the Pokot. In the 19th century, the Nilotic ancestors of these two populations are believed to have begun separate migrations, with one group heading southwards into the African Great Lakes region and the other group settling in southern Ethiopia. There, the early Daasanach Nilotes would have come into contact with a Cushitic-speaking population, and eventually adopted this group's Afro-Asiatic language.

I learned 2 things.
1/ I need to tape a spirit level on the top of that thing to keep the horizon straight. I completely understand why the newest model has it built-in.
2/ Fomapan has horrible reciprocity failure, don't use for long exposures!
Wrapping gifts is always a fun activity - the papers, ribbons and bows, tags, and other decorative miscellany exhibit color, texture, pattern, and, unfortunately, contribution to the world's excessive waste. Recycling can help...as can using more natural elements. Ultimately, the wrap... and the gift... are really about giving, a reflection of warmth and kindness without reciprocity (or so they say!).
