Olen oppinut tuntemaan Olli-Poika Parviaisen jo monen vuoden ajalta, niin Tampereen yliopistolla kuin sen ulkopuolella. Olli-Poika on poikkeuksellinen ihminen: kärsivällinen mutta näkemyksellinen ja sinnikäs; luotettava ja monipuolisesti osaava. Hän on valmis kuuntelemaan, oppimaan ja siten hän myös saa asioita tapahtumaan – rakentavasti ja yhteistyössä, turhaa vastakkainasettelua välttäen. O-P:n monet asiantuntemus- ja osaamisalueet jaksavat aina hämmästyttää. Hän tuntee niin tiedemaailmaa (hänellä on maisteritutkinto meidän kansainvälisestä pelitutkimuksen maisteriohjelmastamme) kuin elinkeinoelämää ja sote-maailman haasteita. Hän on luovien alojen ja digitaalisuuden puolestapuhuja, joka tietää myös miten tärkeää on laatia eettiset pelisäännöt teknologian soveltamiselle ja turvata ihmisoikeudet kaikille myös digitalisoituvassa tulevaisuudessa. O-P tekee pitkäjänteistä työtä paremmin toimivan ja tasa-arvoisemman yhteiskunnan puolesta.
Olli-Pojan osaaminen ja tietämys on noteerattu ja hänelle on kertynyt laajaa kokemusta monissa eri tehtävissä: yrittäjänä, Tampereen kaupunginvaltuutettuna ja varapormestarina, monien eri toimikuntien jäsenenä, sekä kansanedustajana vuodesta 2015 lähtien. Hän on toiminut aitiopaikalla niin eduskunnan hallintovaliokunnassa, tulevaisuusvaliokunnassa kuin mm. valvonut Euroopan ihmisoikeussopimuksen toteutumista Suomen edustajana Euroopan Neuvoston kokouksissa.
Tämän lisäksi O-P onnistuu vielä jotenkin myös navigoimaan kahden pienen lapsen isänä arjen haasteet – sekä vielä löytämään aikaa niin roolipeli- kuin musiikkiharrastuksellekin. Hatunnoston paikka.
I have kept a diary, too, but I think that the best record of life and times comes from the photographs taken over the years. Much of the last century (pre-2000s) photos of mine are collected in traditional photo albums: I used to love the craft of making photo collages, cutting and combining pieces of photographs, written text and various found materials, such as travel tickets or brochure pieces into travel photo albums. Some albums were more experimental: in pre-digital times it was difficult to know if a shot was technically successful or not, and as I have always mostly worked in colour rather than black-and-white, I used to order the film rolls developed and every frame printed, without seeing the final outcomes. With some out-of-focus, blurred or plain random, accidental shots included into every film spool, I had plenty of materials to build collages that were focused on play with colour, dynamics of composition or some visual motif. This was fun stuff, and while one certainly can do this (and more) e.g. with Photoshop with the digital photos, there is something in cutting and combining physical photos that is not the same as a digital collage.
The first camera of my own was Chinon CE-4, a budget-class Japanese film camera from the turn of 1970s/1980s. It served me well over many years, and with it’s manual and “semi-automatic” (Aperture Priority) exposure system and support for easy double exposures.
I started transitioning to digital photography first by scanning paper photos and slides into digital versions that could then be used for editing and publishing. Probably among my earliest actual digital cameras was HP PhotoSmart 318, a cheap and almost toy-like device with 2.4-megapixel resolution, 8 MB internal flash memory (plus supported CompactFlash cards), a fixed f/2.8 lens and TTL contrast detection autofocus. I think I was shooting occasionally with this camera already in 2001, at least.
Few years after that I started to use digital photography a bit more in travels at least. I remember getting my first Canon cameras for this purpose. I owned at least a Canon Digital IXUS v3 – this I was using at least already in the first DiGRA conference in Utrecht, in November 2003. Even while still clearly a “point-and-shoot” style (compact) camera, this Canon one was based on metal construction and the photos it produced were a clear step up above the plastic HP device. I started to convert into a believer: the future was in digital photography.
After some saving, I finally invested into my first digital “system camera” (DSLR) in 2005. I remember taking photos in the warm Midsummer night that year with the new Canon EOS 350D, and how magical it felt. The 8.0-megapixel CMOS image sensor and DIGIC II signal processing and control unit (a single-chip system), coupled with some decent Canon lenses meant that it was possible to experiment with multiple shooting modes and get finely-detailed and nuanced night and nature photos with it. This was also time when I both built my own (HTML based) online and offline “digital photo albums”, but also joined the first digital photo community services, such as Flickr.
It was five years later, when I again upgraded my Canon system, this time into EOS 550D (“Rebel T2i” in the US, “Kiss X4” in Japan). This again meant considerable leap both in the image quality and also in features that relate both to the speed, “intelligence” and convenience of shooting photos, as well as to the processing options that are available in-camera. The optical characteristics of cameras as such have not radically changed, and there are people who consider some vintage Zeiss, Nikkor or Leica camera lenses as works of art. The benefits of 550D over 350D for me were mostly related to the higher resolution sensor (18.0-megapixel this time) and the ways in which DIGIC 4 processor reduced noise, provided much higher speeds, and even 1080p video (with live view and external microphone input).
Today, in 2019, I am still taking Canon EOS 550D with me in any event or travel where I want to get the best quality photographs. This is mostly due to the lenses than the actual camera body, though. My two current smartphones – Huawei Mate 20 Pro and iPhone 8 Plus – both have cameras that come with both arguably better sensors and much more capable processors than this aging, entry-level “system camera”. iPhone has dual 12.0-megapixel sensors (f/1.8, 28mm/wide, with optical image stabilization; f/2.8, 57mm/telephoto) that both are accompanied by PDAF (a fast autofocus technology based on Phase Detection). The optics in Huawei are developed in collaboration with Leica and come as a seamless combination of three (!) cameras: the first has a very large 40.0-megapixel sensor (f/1.8, 27mm/wide), the second one has 20.0-megapixels (f/2.2, 16mm/ultrawide), and the third 8.0-megapixels (f/2.4, 80mm/telephoto). It is possible to use both optical and digital zoom capabilities in Huawei, make use of efficient optical image stabilization, plus a hybrid technology involving phase detection as well as laser autofocus (a tiny laser transmitter sends a beam into the subject, and with the received information the processor is capable of calculating and adjusting for the correct focus). Huawei also utilizes advanced AI algorithms and its powerful Kirin 980 processor (with two “Neural Processing Units, NPUs) to optimize the camera settings, and apply quickly some in-camera postprocessing to produce “desirable” outcomes. According to available information, Huawei Mate 20 Pro can process and recognize “4,500 images per minute and is able to differentiate between 5,000 different kinds of objects and 1,500 different photography scenarios across 25 categories” (whatever those are).
But with all that computing power today’s smartphones are not capable (not yet, at least) to outplay the pure optical benefits available to system cameras. This is not so crucial when documenting a birthday party, for example, as the lenses in smartphones are perfectly capable for short distance and wide-angle situations. Proper portraits are somewhat borderline case today: a high-quality system camera lens is capable to “separate” the person from the background and blur the background (create the beautiful “bokeh” effect). But the powerful smartphones like iPhone and Huawei mentioned above come effectively with an AI-assisted Photoshop built into them, and can therefore detect the key object, separate it, and blur the background with algorithms. The results can be rather good (good enough, for many users and use cases), but at the same time it must be said that when a professional photographer aims for something that can be enlarged, printed out full-page in a magazine, or otherwise used in a demanding context, a good lens attached into a system camera will prevail. This relates to basic optical laws: the aperture (hole, where the light comes in) can be much larger in such camera lenses, providing more information for the image sensor, the focal length longer – and the sensor itself can also be much larger, meaning that e.g. fast-moving objects (sports, animal photography) and low-light conditions will benefit. With several small lenses and sensors, the future “smart cameras” can probably provide an ever-improving challenge to more traditional photography equipment, combining, processing data and filling-in such information that is derived from machine learning, but a good lens coupled with a system camera can help creating unique pictures in more traditional manner. Both are needed, and both have a future in photography cultures, I think.
The main everyday benefit of e.g. Huawei Mate 20 Pro vs old-school DSLR such as Canon EOS 550D is the portability. Few people go to school or work with a DSLR hanging in their neck, but a pocket-size camera can always travel with you – and be available when that unique situation, light condition or a rare bird/butterfly presents itself. With the camera technologies improving, the system cameras are also getting smaller and lighter, though. Many professionals still prefer rather large and heavy camera bodies, as the big “grip” and solid buttons/controls provide better ergonomics, and the heavy body is also a proper counterbalance for large and heavy telephoto lenses that many serious nature or sports photographers need for their work, for example. Said that, I am currently thinking that my next system camera will no longer probably be based on the traditional SLR (Single-Lens Reflex) architecture – which, btw, is already over three hundred years old, if the first reflex mirror “camera obscura” systems are taken into an account. The mirrorless interchangeable lens camera systems are maintaining the component-based architecture of body+lenses, but eliminate the moving mirror and reflective prisms of SLR systems, and use electronic viewfinders instead.
I have still my homework to do regarding the differences in how various mirrorless systems are being implemented, but it also looks to my eye that there has been a rather rapid period of technical R&D in this area recently, with Sony in particular leading the way, but the big camera manufacturers like Canon and Nikon now following, releasing their own mirrorless solutions. There is not yet quite as much variety to choose for amateur, small-budget photographers such as myself, with many initial models released into the upper, serious-enthusiast/professionals price range of multiple-thousands. But I’d guess that the sensible budget models will also follow, next, and I am interested to see if it is possible to move into a new decade with a light, yet powerful system that would combine some of the best aspects from the history of photography with the opportunities opened by the new computing technologies.
