Well, I'm almost done making one for my 580EX....I was confused with the mxwphoto's skematics...so instead of angles in my ring, I made it circular.

I'm almost done, but I'm having trouble figuring out how to make this 90* angle.

Hi jcw, sorry for the late reply. I've been busy. Anyway, to let the light reflect 90 degrees, simply angle the reflector at a 45 degree angle at the joint of the "L" shaped flash ring.

Honestly please tell me you got your idea from the air scrubber rig they had to make out of common parts in the Apollo 13 mission :cool:

Actually, I got inspired after looking at this giant foam ring flash with a dedicated flash plugged in (external link). :)

They carry extension kits for the solar skylights at Home Depot made from specular aluminum (95-98% reflectivity) for $28 for a 2' X 2' section. You can cut it with scissors too =) I just built a faceted reflector for my reef tank from it.

Hehe.. well done... foil tape sounds really intriguing. Now just take a bunch of money shots, stitch them together, and press "print". :D

Thanks!

I worked out the issues and it's working fairly well now. Still a little too much light on top, but at least I know why now and i'm working on it. I change the shape to utilize the focusing light. That works well. If anyone wants more info on it lemme know.

Final cut. I bought some foil tape at Home Depot for $2.50. That worked well for getting the light to the bottom of the ring. Also, the main deflector has a slight fold in the middle that you can just barely make out...further directing the light around the sides.

Andrew. Taken in darkness. Camera was able to focus and illuminate fairly evenly. Lens was about 1/2" away.

I think your cam is similar to S3, what is your measurement of your design if dont mind please.

Thanks

One of the coolest things I have ever seen. I wonder how using plastic caps (like from various-sized spray cans and such) would work. Cut them, line them with mylar, and use that on the end around the lens.

VERY cool! I'm having some days off soon, if the weather is bad I'm going to try and make 430-version of this!

So this only works for macro, or would it work for portraits too? I'd be curious to see a sample shot. Great idea!

Hi Tommy,

Is there a reason why you have the ring so far above the actual head of the flash?
