Nyt kun Atelieri O. Haapala on pist\u00e4nyt kabinettikuva-projektinsa pakettiin, pit\u00e4\u00e4 t\u00e4llaisten vintage-henkisist\u00e4 kuvista innostuneiden henkil\u00f6iden keksi\u00e4 vaihtoehtoisia vintage-kuvaamoita. Yksi eritt\u00e4in kiinnostava sellainen l\u00f6ytyy Porista, he j\u00e4rjestiv\u00e4t m\u00e4nn\u00e4 viikonloppuna kuvausp\u00e4iv\u00e4n Tampereella. Studio 1851<\/a> ottaa kuvia m\u00e4rk\u00e4-kollodium-tekniikalla, jossa kuva valotetaan suoraan\u00a0m\u00e4r\u00e4lle mustalle alumiinilevylle. Kuulostaa aika hurjalta. Min\u00e4p\u00e4 kerron lis\u00e4\u00e4!<\/p>\n

M\u00e4rk\u00e4-kollodium-menetelm\u00e4 keksittiin 1851 ja se oli aktiivisessa k\u00e4yt\u00f6ss\u00e4 noin kolmisenkymment\u00e4 vuotta kunnes paremmat valokuvaustekniikat syrj\u00e4yttiv\u00e4t sen v\u00e4hitellen. M\u00e4rk\u00e4levytekniikoissa kuva valotetaan suoraan kollodiumilla k\u00e4sitellylle, valoherkistetylle, m\u00e4r\u00e4lle levylle. Levy\u00a0voi olla lasia tai esim alumiinia. Levy k\u00e4sitell\u00e4\u00e4n kollodiumilla jonka j\u00e4lkeen se herkistet\u00e4\u00e4n valolle hopeanitraatilla. T\u00e4m\u00e4n j\u00e4lkeen levy valotetaan kameralla sen ollessa viel\u00e4 m\u00e4rk\u00e4. Jos levy ehtii kuivua, se ei valotu eik\u00e4 kuvaa muodostu. Lasilevylle valotetusta kuvasta (negatiivi)<\/strong><\/span> voidaan valmistaa l\u00e4hes rajattomasti uusia kuvia paperille, mutta metallilevylle valotettu kuva on ainutkertainen eik\u00e4 sit\u00e4 voida toistaa muutoin kuin modernisti skannaamalla alkuper\u00e4inen kuva. Metallilevylle kehitettyn\u00e4 negatiivia ei j\u00e4\u00e4 j\u00e4ljelle vaan lopputuloksena on yksi ainoa positiivikuva.<\/p>\n

Satunnaisena valokuvauksen harrastajana erilaiset vanhat kuvaustekniikat kiinnostavat, vaikka harvemmin itse en\u00e4\u00e4 harrastemieless\u00e4 kuvaankaan muuten kuin blogia varten. Itse pid\u00e4n kovasti t\u00e4m\u00e4n tekniikan kontrastisuudesta ja siit\u00e4 miten se saattaa paljastaa kuvasta yll\u00e4tt\u00e4vi\u00e4 asioita, kuten piilevi\u00e4 pisamia kuvattavan kasvoilla. Vaikka kuvat ovatkin mustavalkoisia, n\u00e4iss\u00e4 kuulemma v\u00e4rit toistuvat v\u00e4h\u00e4n eri tavoin kuin tavallisessa mustavalko-kuvassa. Esim keltainen ja kirkas punainen n\u00e4kyv\u00e4t voimakkaammin kuin tavallisessa mv-kuvassa. Is\u00e4nt\u00e4 n\u00e4ytt\u00e4\u00e4 kuvissa harmaahapsisemmalle kuin luonnossa, min\u00e4 taas tummakutrisemmalle kuin oikeasti. Kokemuksenakin kuvaus poikkesi tavallisesta sill\u00e4 kuvattava p\u00e4\u00e4see n\u00e4kem\u00e4\u00e4n miten kuva todella muodostuu alumiinilevylle ja kuvaajat samalla selitt\u00e4v\u00e4t prosessin kulkua.<\/p>\n

Now when Atelieri O. Haapala has finally finished and packed up their cabinet photography project, people who love vintage style portraits must find other options for vintage style photo studios. One rather interesting is located in Pori, they arranged photo shoot last weekend in Tampere. Studio 1851<\/a> is using wet-collodion process for photos. Photo is exposed directly on wet black aluminium plate. Sounds rather wild don’t you think. Let me tell you more!<\/p>\n

Wet-collodion process was invented in 1851 and it was in active use in about 30 years untill more advanced techniques overtook the photography business. On wet plate process the photograph is being exposed directly on wet plate which has been covered with collodion solution and then treated with silver nitrate to make it light sensitive. Plate can be glass or even aluminium. Then plate is exposed in a camera while still wet. If plate dries, photo does not expose. When photo (negative)<\/strong><\/span> is exposed to glass plate, it’s possible to make almost infinite amount of paper photos with that. But when it’s exposed to metal plate, it is unique and cannot be replicated except by modern methods, scanning original\u00a0to computer and printing it. There won’t even be a negative left, there will be only one, positive photo.<\/p>\n

As an accidental hobby-photographer I’m interested in old photography techniques, even though I don’t really photograph much these days except for the blog. I like very much how this particular technique shows lots of contrast and how it might even reveal surprising things, like hidden freckles on models face. Even though photos are black and white, apparently they show colours in a different way than ordinary black and white photos. For example yellow and bright red show darken than usual. Hubby looks much more gray on the hair than he really is and I seem to have much darker hair than I really do. As an experience this was also quite different than usual photo shoot would be. You get to see how the photo really appears on the aluminium plate and photographers talk you through the whole process.<\/p>\n

Is\u00e4nt\u00e4 poseeraa, eli nojaa p\u00e4\u00e4t\u00e4\u00e4n niskatukeen sill\u00e4 valotusaika oli hurjat<\/strong><\/span>
\nkuusi sekuntia kun normaalisti puhutaan sekunnin kymmenes- tai sadasosista. \/<\/strong><\/span>
\nHubby posing, aka leaning his neck on neck rest. Exposure time was outrageous<\/strong><\/span><\/em>
\nsix\u00a0seconds, when usually it’s about tenths or hundreds of a second.<\/strong><\/span><\/em><\/p>\n

\"wetplatephoto2\"<\/a><\/p>\n

T\u00e4m\u00e4 on kai sit\u00e4 kollodiumia, mik\u00e4li ymm\u00e4rsin oikein. \/<\/strong><\/span>
\nI assume this is collodion if I understood correct.\u00a0<\/strong><\/span><\/em><\/p>\n

\"wetplatephoto3\"<\/a><\/p>\n

Ja n\u00e4m\u00e4 mustat levyt ovat kuvapohjia joille kuva valotetaan ja sitten kehitet\u00e4\u00e4n. \/<\/strong><\/span>
\nAnd these black plates are the photo base where it’s first exposed and then developed on.\u00a0<\/strong><\/em><\/span><\/p>\n

\"wetplatephoto4\"<\/a><\/p>\n

Siell\u00e4 ne huuhtoutuvat ritirinnan. \/<\/strong><\/span>
\nPhotos are now rinsing side by side.\u00a0<\/strong><\/span><\/em><\/p>\n

Ja t\u00e4ss\u00e4 n\u00e4m\u00e4 valmiit kuvat nyt ovat. Ep\u00e4tasaiset reunat johtuvat siit\u00e4 miten kehiteaine
\non\u00a0<\/strong><\/span>osunut kuvan pintaan. Vinot raidat ovat ehk\u00e4 levyn pinnassa olevaa tekstuuria,
\nen tied\u00e4\u00a0<\/strong><\/span>viel\u00e4 varmaksi kun saamme varsinaiset fyysiset kuvat vasta loppuviikosta. \/<\/strong><\/span>
\nAnd here are the final photos. Uneven edges are due to how the developer spreads<\/strong><\/span><\/em>
\naround the photo. Diagonal stripes are perhaps the surface texture of the plate,\u00a0<\/strong><\/span><\/em>
\nI’m not sure yet, because we will get the actual photos by end of the week.\u00a0<\/strong><\/span><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
