The trouble with glass is that it tends to double reflections; it reflects off the top, which you want, and off the bottom, which you don't. The more oblique the angle, the more it messes up. Also, ordinary glass tends to be on the green side. You can back glass with a black paper if you want a reflection on dark, and it works pretty good.

I'm not up-to-date onw hat's cuurent and "modern" for this. Someone surely will be.

Are you trying to bounce light around or photograph a reflected image?

If the former, the cheapest source is the aluminized Mylar found on the inside lining of many potato chip bags.

If the latter, buy a cheap mirror -- that's what they're made for.

I like to get mirror material from these folks.
//www.pgo.com/products/mal.htm

They sell very high quality mirror and from what I remember they
are fairly cheap. They will cut to size, but there is a cutting fee.

yes but i don't want a refletion to be very obvious... it has to be a large thing to reflect, i am using only lights to make the reflection, and i've tried glass on the black droplet...
i don't think a mirror will do, obviously it will but it had to be a large mirror and that would be very expensive.

Try calling a fabric or crafts store -- I believe that aluminized Mylar is available on rolls about 60" wide.

01/26/2005 07:05:01 PM · #9

what color is that aluminized Mylar?

Plexiglass works well. It can be bought and cut to size at any hardware store. I'll dig up a sample and be back.

thanks i'll be waiting for the sample... thanks

It's usually silver, at least on one side. It might be colored/printed on the other side. It's the stuff they make those fancy balloons (and chip bags) out of.

I have some 12" square "tiles" made of glass mirror -- intended for sticking onto a bathroom wall or something. If you don't mind the seams, you could "build" a big mirror from some of those ... Home Depot or other big hardware/home improvement store probably has them.

I would really like the refletion to be in black i know i can bu tiles in black but then there would be some fails on the refletion due to the tile connections.

How about that black plastic sheeting people put down in their gardens? It comes on a long roll. If it's brand-new and you don't crinkle it up too much it might be shiny enough.

How about a sheet of plywood and a can of black gloss enamel (spray) paint? Use with adequate venitlation -- Keep away from fire.

Here's the sample I promised. Not my work, but shows off what you need to see. Sorry for the delay; had to put my daughter to sleep.

Go to your local wrecking yard and see if they have the hood off an old black Cadillac which was -- unlikely as it seems -- totalled from the rear.

How about gift wrapping paper - some comes in shiny, glittery metallic form.
The back of it is often plain silver, gold or even white, but metallic.

If you have a dead videocasette you can extract about 1200 feet of brown or black Mylar "ribbon" -- you could wrap it around a board or hand it like a mirrored "beaded curtain"

Guys thanks a lot the sample that just-married gave is exactly what i want... there are lots of ideias here thanks a lot i'll see if i can get something to work. thanks a lot any more ideias would be aprreciated...
Just married thats Plexiglass right? where can i get it and is it expensive?

01/26/2005 10:09:05 PM · #21

Glad I was able to help. Yes, plexiglass (which is essentially a plastic that can be used to imitate glass). Can be bought at hardware stores like Home Depot or Lowes. Around here it goes for $2-3/sq ft.

Good luck!

Sorry, wasn't considering that you might not be in the states. Very narrow of me. In case the terminology is different, a brief description:

Plexiglass is the stuff used instead of glass in cheap photo frames. Perhaps that can help you identify the word in Portuguese.

Good Luck!

01/26/2005 11:06:26 PM · #24

plexiglass is like a plastic glass right?
