No Lens - Refractography on HIVE

in #hive-1949132 years ago

PATIENCE GAME

I am certainly not the most patient person. Actually, such fumbling is not for me. At the slightest movement of the glass or even the light source, the beautiful refractograph immediately disappears. But my inner voice told me to finally play with the glass shards in front of the camera again last night.

Ich bin ganz sicher nicht der geduldigste Mensch. Eigentlich ist solch ein Gefummel nichts für mich. Bei der kleinsten Bewegung des Glases oder auch der Lichtquelle ist der schöne Refraktograph sofort verschwunden. Aber meine innere Stimme befahl mir gestern Abend endlich mal wieder mit den Glasscherben vor der Kamera zu spielen.

The pieces of glass used are fragments and remnants from a glass manufactory. The glass is of high quality. The manufactory uses it to make art objects and high-quality utensils. But in principle, this also works with other things made of glass, such as wine glasses or similar.

Die verwendeten Glasstücken sind Bruchstücke und Reste aus einer Glasmanufaktur. Das Glas ist von hoher Qualität. Die Manufaktur fertige daraus Kunstobjekte und hochwertige Gebrauchsgegenstände. Aber grundsätzlich funktioniert das auch mit anderen Dingen aus Glas, wie Weingläsern oder Ähnlichem.

Here you can see the basic structure. The camera is mounted on the tripod without the lens. The glass object is placed in front of the camera. I had screwed a macro ring from the 3D printer onto the camera so that I wouldn't accidentally hit the sensor when moving the glass object in the dark. Then I taped the head of the Fenix PD36R with gaffa tape and poked a small hole in it. I placed the lamp about 2 metres away. I then directed the small beam of light parallel to the camera onto the glass object.

Hier seht ihr den grundsätzlichen Aufbau. Die Kamera wird ohne Objektiv auf dem Stativ befestigt. Das Objekt aus Glas wird vor der Kamera platziert. Ich hatte einen Makroring aus dem 3D Drucker an die Kamera geschraubt damit ich in der Dunkelheit beim Bewegen des Glasobjekts nicht versehentlich den Sensor treffe. Dann hatte ich den Kopf der Fenix PD36R mit Gaffa Tape zugeklebt und in dieses ein kleines Loch gestochen. Die Lampe hatte ich in ca. 2 Metern Entfernung platziert. Den kleinen Lichtstrahl hab ich dann parallel zur Kamera auf das Glasobjekt ausgerichtet.

I switched on Live View and moved the glass in front of the camera until a half-decent refractograph became visible and then triggered the camera. I had worked with exposure times of 1/8 to 1 second. The ISO value was either 100 or 400. In some of the pictures I had coloured parts of the image with small pieces of colour filter foil.

Ich schaltete den Live View ein und bewegte das Glas solange vor der Kamera bis ein halbwegs ansehnlicher Refraktograph sichtbar wurde und löste dann die Kamera aus. Ich hatte mit Belichtungszeiten von 1/8 bis 1 Sekunde gearbeitet. Der ISO Wert war entweder 100 oder 400. Bei einigen Bildern hatte ich mit kleinen Stücken Farbfilterfolie Teile des Bildes eingefärbt.

The esteemed Rob Turney published a very good tutorial on refractography a few years ago. You can find it here:

WHAT IS LIGHT PAINTING?

Light painting is a unique form of art. The darkness is illuminate by the artist with diverse light sources and light traces are paint into the picture with various light tools. Various techniques are use, such as camera rotation or other movements of the camera during the exposure. The creative possibilities are almost unlimited. All the pictures were taken during one single exposure. Apart from denoising, sharpening, cutting and possibly adjusting the white balance, the pictures are not processed on the computer.

Nice experiments.

😊

Really interesting photos. New idea for me to look at, thanks for the inspiration. I'm not I trust myself not to damage something I shouldn't in the process, lol. State of mind kind of thing, lots of patience and fiddling around required. Not sure if you're familiar with minerals, but have you ever tried out optical calcite, a good quality polished piece that is?

In the photos there's a smoke-like feel in quite a few. There's this "webbing" of light, which makes me think of cobwebs and most have this otherworldly feeling. I like the subtle use of colour and very abstract nature.

Thanks for including the tutorials as well, much appreciated!

Give the minerals a try. I only used glass till now. Can't wait to see the results. But I think polish and shiny things will do no better refractographs. It is not about the surface. It is about little "errors" in the material.

I've shot the minerals using sunlight to make some funky photos, but not posted anything yet because I suck at posting regularly. I need to set up inside to shoot like that in a way that I don't cause mass destruction in my apartment, lol.

It is not about the surface. It is about little "errors" in the material.

This is what I see from playing with sunlight and glass is far better than plastic in terms of those "errors". I did get inspired to set up in my bathroom for some indoor, very basic light painting and made it more annoying by using my macro lens (small bathroom) and got some interesting shots, but what I consider to be experimental. I will try to post those because I wouldn't have tried this without seeing all these incredible lightpaintings, plus the technical aspects.

Sehr interessanter Beitrag und spannende Ergebnisse. Du hast zu Beginn deines Artikels etwas von Makroring geschrieben, der dient nur dem Schutz des Sensors? Oder wie darf ich das genau verstehen?🤔

Der Makroring dient hauptsächlich dem Schutz des Sensors vor Beschädigungen durch die scharfen Glasteile. Wenn das Glas größer ist als die Öffnung der Kamera mach ich den Ring nicht dran. Aber so nebenbei kann man den Winkel der Taschenlampe verändern, ohne dass man ins Gehäuse der Kamera leuchtet. Aber irgendwann sieht man dann doch den Ring im Bild wenn Licht darauf fällt.

Ah ok, dann habe ich das doch richtig verstanden 😊. Danke

😊

Good experiments, the result ended up really great

neat abstract photography

Thanks 😊

Yay! 🤗
