lighting thoughts/questions
Larry's words... I wonder if anyone has tried simulating a ring light for macro work, by putting a studio strobe with umbrella directly behind the camera and triggering the camera with a cable release? In a similar vein, what is the fabric that is used for shoot through umbrellas, soft boxes etc? It seems I could make a really big softbox for a lot less than it would cost to buy, if I bought the right fabric, plastic or whatever is used for the diffuser. -- Larry Colen lrc at red4est.com sent from i4est Larry, I did use a large softbox and a small silver umbrella behind the camera some two or three times, but results did not get me smiling - the umbrella gave better results for my taste, but more often I'd place the light from a side or use the softbox as part of a light tent, not always at the top. My tests happened in studio - it's conceivable to get some structure to use an umbrella attached to the camera in the field, probably even available somewhere. A friend and teacher built a gadget with a glass panel at 45 deg from the camera, that would receive a studio flash and reflect part of the blast towards the subject's face. He wanted to do some portraits with a fully frontal light, no shadows visible and wanted real power. Results were interesting to a point, but the glass at our disposal then (1982-3, Brasilian northeast) made him quit. I suggested a hole in front of the lens, but he also wanted to get rid of donut shaped reflections on eyes. As for the clothing/ plastic used on softboxes, I used white plastic, vegetable paper and ordinary white synthetic cloth to repair or improvise softboxes and light diffusers in the past - color casts were the issue since most of the time I'd be using slide film, but a slight cast was better than failing to present the pic. It helped when all lights used the same solution. The softboxes available here in Br do age and develop some color cast sooner or later - so I'll probably have to repair mine soon, again. ps: as the first try to send this msg failed, I looked at the other answers and there is some rig to use umbrellas that way. -- luiz felipe luiz.felipe at luizfelipe.fot.br -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

It seems I could make a really big softbox for a lot less than it would cost to buy, if I bought the right fabric, plastic or whatever is used for the diffuser. An idea I've been thinking about for a while and might pursue if I ever get "a round tuit" is taking the strobes off a bunch of disposable cameras and building some kind of ring platform to mount them on; maybe a plastic "bundt cake" pan would work. Gotta be careful to make sure the electrical components are protected; sealed away where they can't zap you. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

I used to use a device called a sof' shoulder for macro. It's no longer available, but it was an umbrella and flash on a rig that was positioned it over the photographer's shoulder.
