I have been using reflectors made for your car windshield to shade people when forced to shoot in hard light. I am looking to upgrade, I think I want a diffuser so some light from the sun comes thru and something fairly large. Also what arm do you recommend I get for assistant to hold it the easiest? Any advise you have would be greatly appreciated...

Search is your friend (key word: diffusers, this forum is ok). There has been many posts on this issue, including this (http://www.dgrin.com/showthread.php?t=26887&highlight=diffuser)..

Giselle,
It sounds like you want an "overhead" diffusion panel?
There are many ways to go, commercial and DIY. I tend to go DIY, when possible, and I've been looking into these as well.
The best designs are either based on a free-standing tent, with flexible poles, or a more ridgid design, made from PVC pipe or similar, kind of like a car port design.
The diffusion material itself is usually either plastic sheet or rip-stop nylon. One clever person, I read about a couple of years ago, got some old parachutes, and put them to use as the diffusor material.
If you want a simple, smaller, hand-held device, a hula-hoop, with the diffusion material stitched over the hoop, is said to work well, as do simple rectangular/square frames made out of PVC pipe.
I had some bookmarks, but I think they got lost last year. If I see anything, I'll post it here.

The best way to do this is to use Scrim Flags and Panels/Butterflies. These are panels made out of Silk or other fabrics that you can use to reduce the power of the sun or a large flood. Smaller ones are usually in 1/4, 1/2 stop, etc... Butterflys big enough for cars are usually 1 to 2 stop loss.
If you buy a butterfly usually you can get reflective material for the frames as well, which is a bonus.
Most pro shop photography stores have flags and panels usually.
I use rip-stop nylon in my 2'x2'x3' light box. It really eats up light. 4x 500 watt bulbs is the minumum to light the space.

I almost forgot, a large shoot-through photographic umbrella can also be used in a pinch. Some have removable shafts, making it easier to get them close to the subject, or they can be used inverted.
I'm sure I had more, but duty calls. (Scouting stuff.)

Thats a great find Art. Most muslin from the fabric store is more than that per yard.

Thanks for all the ideas and info. Does anyone know anything about the sun swatter? http://www.sunbounce-usa.com/swatt_the_light.html
It cost too much but looks really cool.

Those are just panels with either diffusing material or reflective material.
I haven't heard of them but the technology behind panels is pretty simple, its just fabric and stop loss thats really important.
BTW, they do work as well as shown on that site. Its pretty cool how something so simple can be a big and soft light source.
