Here is a good example of what I we need:

http://www.facebook....5835e8bdae177f5

Shooting on an Sony EX1

In a studio I reckon I could give this a crack, pump the wattage at the wall/cyc - keep some separation between the subject and the wall so the wall will be out of focus and wont backlight them too much - and then light the subject away as you normally would, maybe to a lesser extent in terms of power so that you could open iris to blow away the background...

Now I may not have access to much lighting for this gig - I know, I know (!) information is exactly what I need to give here but does anyone have any tips for this sort of shot ? could backlighting some diffusion an idea if head shots is all they turn out to be after ?

Maybe it doesn't need to be so lighting intensive ? If it is what sort of wattage am I looking at to get a wall (assume white) to peak out a sensor to such an extent ?

Are there any color temp issues to think about ?

Aside from some grading/tweaking I'm not after a digital/post solution if possible.

thanks you for any info,

Chris

You answered your own question. You are only limited by how much area of white you can light to blow out. It's easier than you think.

Any idea of the sort of wattage in a couple of fresnels I'd looking at to get a white wall about 2 x 3.5m to peak out a sensor to such an extent ?

Of course it all relates to how sensitive your camera is and what stop you are shooting at etc. Also how white is that white wall to begin with. If you put up some brand new bead board, white card, etc. as a back drop I would guess minimum would be a couple of Tweenies or better yet Teenie Moles. Personally I would start with a couple of Red Heads or maybe a couple of Blondes through diff frames to even it out.

The example you've shown is called "High Key Lighting". Below is a link explaining the best ways to achieve this. It's very informative albeit being a still photographers website. but worth reading.

I'd be careful about using fresnels. Use an open faced unit through some diff as previously mentioned.
