DIY Diana flash trigger

Check out photographer Don Brice‘s excellent modification that allows you to use normal flash/strobe units on Diana toy cameras:

I enjoy using the Diana in the studio and shooting portraits and still life lit with flash. I discovered long ago that by ripping off the usual connector on the end of the syncro cable, you could bare the two wires and jam them down the two flash sockets on the Diana-F model. Ta-da. Plug the other in to your strobes and away you go…

Homemade strobe slave

Photography enthusiast Nick Pagazani was hindered by the range and fixed location of his camera’s flash. Since his camera has no connector for an external flash, he needed a light-activated slave trigger to fire a remote strobe. It had to ignore the pre-flashes used for red-eye correction and fire only on the main flash. His solution: Use a microcontroller to count pulses from a phototransistor and trigger the strobe at a switch-selectable count. Brighten up your shadowy background with this flashy accessory.

Homemade flash diffusor from take-away container

Homemade flash diffusor

Flickr member potatomato posted a photo set on how he made a flash diffusor from a plastic take-away container.

He writes:

The Gary Fong Lightsphere is a flash diffuser that is gaining popularity with wedding and portrait photograhers world wide. His product is selling at a pace that the manufacturer can’t keep up with. This Flickr photoset demonstrates the use of a to-go container to make your own.

“Starving student” off-camera light kit

The SSO-CLK (for lack of a more poetic term) is designed to give you the most bang for your buck – with a nod toward extreme portability. It will work well with any camera that can be controlled manually and has a PC synch jack. Most SLR’s, digital or film, fit this bill. The flash is a vintage Nikon model, but it will work off-camera with anything that has a PC jack…

Digital photography with flash and no-flash image pairs

Digital photography has made it possible to quickly and easily take a pair of images of low-light environments: one with flash to capture detail and one without flash to capture ambient illumination. We present a variety of applications that analyze and combine the strengths of such flash/no-flash image pairs. Our applications include denoising and detail transfer (to merge the ambient qualities of the no-flash image with the high-frequency flash detail), white-balancing (to change the color tone of the ambient image), continuous flash (to interactively adjust flash intensity), and red-eye removal (to repair artifacts in the flash image). We demonstrate how these applications can synthesize new images that are of higher quality than either of the originals.

Canon launch Flash Work site for EOS flash photography

Canon just launched a new mini-site dedicated to flash photography with the EOS/EOS Digital + Speedlite combo. It also has a Lighting Techniques section with diagrams and example photos that applies to flash in general.

Also, I strongly recommend that anyone using EOS flash—on film or digital bodies—read NK Guy’s excellent article, Flash Photography with Canon EOS Cameras, on photonotes.org, as many times as it takes to truly understand it. It’s long and complicated, but explains exactly how the whole system works, and has definitely helped me make better flash photos with the EOS system.
