| p.1 #5 · Better high ISO perfromance sensors and the future of strobes? |
With new cameras getting better and better ISO performance, does anyone envision a slow move towards more continuous light set-ups like Kino Flo and moving away from strobes? I think that with better high ISO performance my preference may move more towards wanting to use continuous light. I like the WYSIWYG. Sure, there are modeling lamps but nothing beats seeing it as it is. Heat is obviously an issue and that's why I listed Kino Flo.
Well, back in the early 70s I was shooting in a tungsten-powered studio with medium format cameras. I had 3000 watts of tungsten light (1000 watts in the main light). That light gave me f5.6 at 1/60 on ASA (!) 400 film.
Today, I'm getting the same image quality in a 24x36mm DSLR at ISO 100, but with electronic flash I can shoot at f/11 and an effective shutter speed of 1/1000.
We're still a long way from getting cold light into a package as small and powerful as a 1000 watt tungsten bulb, but let's say we did. I'd be shooting at f/5.6 and 1/250 at ISO 1600...and we're probably a long way from having ISO 1600 quality that is as good as ISO 100 today.
But to get to where I already am with electronic flash--f/11 at 1/1000-- with the lumen equivalent of that tungsten 1000 watt bulb, I'd actually have to have ISO 6400 that is the equivalent of today's ISO 100.
