Portable light box. The light tent is the most convenient solution for making professional photos of a wide range of products: by placing products in the tent and illuminating the tent from the outside, you obtain the best exposure for professional product photos.
I wanted my own foldable and portable light tent with the extra comfort of having its own build in lighting. Benefits: • Build in lighting • Prevents reflections • Seamless transition from background to foreground. Researchers Turn iPhone Camera into Cheap Microscope with $40 Lens. A team of researchers at UC Davis have come up with a super-cheap way of turning an iPhone into a microscope — useful for diagnosing diseases in areas where medical equipment is hard to come by.
Inspired by the CellScope project at UC Berkeley, Sebastian Wachsmann-Hogiu decided to create something even smaller and cheaper. By taping a 1-millimeter ball lens embedded in a rubber sheet to the iPhone, he was able to boost magnification by 5x, which allows the camera to photograph blood cells. Only a small portion of each image is in focus, so they also utilize focus stacking to achieve more usable photos. Double lens reverse macro for an SLR. 1) An SLR or DSLR.2) A zoom lens, around 200mm works really well.3) A fast prime lens, with an aperture ring.4) A macro coupler.5) A tripod in most cases.
Optional6) A remote shutter release.7) An off camera flash, or bounce flash if on camera. In this instructable I'll be using:Nikon D4055-200mm zoom52mm macro coupler50mm f1.8 prime lens Most people will have some sort of zoom, but maybe not a fast prime lens. The 50mm 1.8 D that I have is only about $100 new, and I'm pretty sure most of the other big camera names have a similar priced lens. Plans for improvments. I may see if I can get hold of a more powerful loupe, mine is a 7x magnification & produces some good results but I would love to try a 10x or even a 15x magnification model.
Lighting is a problem, the on camera flash is not a big help in low light as the subject is far too close to the camrea body so I may look into some sort of slave flash or possibly an led arrangment around the body of the loupe. If I can get hold of a suitable camera I may see if I can set up a remote trigger. In the spring I may try the loupe on a webcam hooked up to a laptop, I may even try this year before autumn closes in on us but I need to sort out lighting first. Kirlian photography. Kirlian photograph of two coins Kirlian photography is a collection of photographic techniques used to capture the phenomenon of electrical coronal discharges.
It is named after Semyon Kirlian, who, in 1939 accidentally discovered that if an object on a photographic plate is connected to a high-voltage source, an image is produced on the photographic plate. The technique has been variously known as "electrography", "electrophotography", "corona discharge photography" (CDP), "bioelectrography", "gas discharge visualization (GDV)", "electrophotonic imaging (EPI)", and, in Russian literature, "Kirlianography". Kirlian photography has been the subject of mainstream scientific research, parapsychology research and art. Kirlian Photography - Building your own equipment. What is Kirlian Photography?
Kirlian photography is a high voltage, contact print photography. Kirlian photography is named after Semyon Davidovich Kirlian and his wife Valentina who began their work with high voltage photography in 1939. Kirlian collaborated with his wife for over 30 years developing equipment and studying electro-photography. Kirlian's work was first made known to the general public in this country by a book published in 1970 by Shelia Ostrander and Lynn Schroeder titled "Psychic discoveries Behind the Iron Curtain". Kirlian work became so well know that the field of high voltage electro-photography is called Kirlian Photography.
