Muistatteko lapsuudesta muovipintaiset postikortit joissa korttia k\u00e4\u00e4nnelless\u00e4 kuva liikkui tai n\u00e4ytti kolmiulotteiselle? Ne olivat jotenkin maagisia. Eiv\u00e4t ne kovin yleisi\u00e4 olleet, lapsuudestakin muistan vain muutamia yksitt\u00e4isi\u00e4. Vasta \u00e4skeitt\u00e4in l\u00f6ysin n\u00e4ille korteille nimen. Ne ovat nimelt\u00e4\u00e4n lentikulaarisia kuvia. Kuvan pinnassa on er\u00e4\u00e4nlaisia sauvamaisia muovilinssej\u00e4. Linssien alla on kaksi tai useampia kuvia jotka on suikaloitu hiuksenhienoiksi soiroiksi jotka on aseteltu vierekk\u00e4in sauvamaisten linssien alle. Kukin linssi on jaettu useampaan eri kulmassa olevaan osioon, jotka on asetettu tarkkaan kuvasuikaleiden p\u00e4\u00e4lle. Eri suunnista katsoen kukin linssin osio n\u00e4ytt\u00e4\u00e4 katsojalle erilaisen kuvan ja t\u00e4st\u00e4 syntyy efekti liikkuvasta, muuttuvasta tai kolmiulotteisesta kuvasta. Olen yritt\u00e4nyt etsi\u00e4 sellaisia kortteja kirppiksilt\u00e4, mutta ei ole tullut vastaan. <\/p>\n\n\n\n

Lentikulaarisia kuvia on osattu tehd\u00e4 jo 1500-luvulta l\u00e4htien. Yksinkertaisimmillaan lentikulaarinen kuva on haitarimaiselle pinnalle kiinnitetty, tai maalattu, suikaleista koostuva kuva. Yksinkertaisia lentikulaarisia kuvia voi tehd\u00e4 itsekin. Tarvitset yhden tai kaksi kuvaa (kesken\u00e4\u00e4n samankokoiset). Ohutta kartonkia tai keskivahvaa paperia jota on helppo taitella. Taittele arkki noin 2 cm levyisiksi taitteiksi niin ett\u00e4 niist\u00e4 muodostuu haitari. Tee taitteista tarkalleen samankokoisia kesken\u00e4\u00e4n. Jaa kuva(t) samanlevyisiin suikaleisiin pystysuunnassa ja leikkaa ne irti toisistaan. Liimaa suikaleet samassa j\u00e4rjestyksess\u00e4 haitariin, mutta vain taitosten vasemmalle puolelle. Leikkaa toinen kuva samoin ja liimaa se taitosten oikealle puolelle. Jos taitoksia on enemm\u00e4n kuin kuvasuikaleita, voit v\u00e4ritt\u00e4\u00e4 ne kuvan s\u00e4vyisiksi tai leikata ylim\u00e4\u00e4r\u00e4iset kokonaan pois. <\/p>\n\n\n\n

Aseta haitari p\u00f6yd\u00e4lle, kirjahyllyyn, kiinnit\u00e4 kehyksiin tai katselukaappiin. Kauempaa ohi k\u00e4velless\u00e4 kuva muuttuu katselukulmasta riippuen. Tein t\u00e4m\u00e4n oman kuvan tosi nopsasti iltapuheina joten se on v\u00e4h\u00e4n repsottava sielt\u00e4 t\u00e4\u00e4lt\u00e4, mutta huolellisemmin tehtyn\u00e4 on tietysti viel\u00e4 hienompi. Eik\u00e4 tuota tietysti kauempaa huomaa ett\u00e4 liimaa ei ole ihan joka kulmassa eiv\u00e4tk\u00e4 haitarin sivut ole ihan tasamittaiset.<\/p>\n\n\n

Do you remember those plastic-coated postcards from the childhood where the image moved or appeared three-dimensional when you turned the card? They were somehow magical. They were not very common; I only remember a few from my childhood. I only recently found out what these cards are called. They are called lenticular images. The surface of the image has a kind of rod-like plastic lenses. Underneath the lenses are two or more images that have been sliced into hair-thin strips and placed side by side under the rod-like lenses. Each lens is divided into several sections at different angles, which are placed precisely on top of the image strips. When viewed from different angles, each section of the lens shows the viewer a different image, creating the effect of a moving, changing, or three-dimensional image. I have tried to find such cards second hand, but no luck. <\/p>\n\n\n\n

Lenticular images have been produced since the 16th century. At it’s simplest, a lenticular image is an image consisting of strips attached to or painted on an accordion-like surface. You can make simple lenticular images yourself. You will need one or two images (of the same size). Thin cardboard or medium-weight paper that is easy to fold. Fold the sheet into 2 cm wide folds to form an accordion. Make sure the folds are exactly the same size. Cut the image(s) into strips of the same width vertically and cut them apart. Glue the strips in the same order onto the accordion, but only on the left side of the folds. Cut the other image in the same way and glue it on the right side of the folds. If there are more folds than picture strips, you can color them to match the picture or cut off the excess completely.<\/p>\n\n\n\n

Place the accordion on a table, bookshelf, attach it to a frame or in a display cabinet. When walking past from a distance, the image changes depending on the viewing angle. I made this picture really quickly in couple of hours, so it’s a little rough around the edges, but if you take more care, it will of course look even better. And of course, from a distance you can’t see that the glue isn’t quite in every corner and the sides of the accordion aren’t quite even.<\/p>\n\n\n

You can glue the accordion from the back side ridges onto picture frame. That way it’s easy to hang on the wall and it stays straight. <\/em><\/strong><\/figcaption><\/figure><\/div>\n\n
