A first-surface mirror will eliminate the dreaded double-reflection.

Where can you get this?

Thanks!

plexi will give you a double reflection. Just use something shiny.

Example of Plexi.

This looks like a piece of plexi mirror. Is that what it is? If you use a piece of black pexi (colored through), it will give you the same effect (a little darker) with no double reflection...

No, it was only smoked plexi. No mirror what so ever.

I guess the smoked isn't opaque enough. I use solid black.

Thanks!

Look for a plastics shop in the area, like TAP Plastics (might have online ordering). You can get solid color acrylic.

I also like using granite tiles that are well buffed. Shiny, but with enough texture to be interesting.

Someone said you get duplicate reflections from plexi. This has not been my experience, and I shoot a ***LOT*** of reflection shots on plexi.


I believe these people use 2 light sources.

Another source for really nice affordable sheets of high grade plastic sheets is to keep any eye out for old projection style big screen TV's, especially ones made by Sony. I had one and bought an optical grade tinted (read polarized) front panel that can be detached. I use it all the time. I did paint the back side a flat black which made for a great black background for product shots. I've found on transparent and even semi-transparent sheets the different gloss-types make for a different result.

Also, you can pickup any number of either plastic resurfacing kits or even stuff from your local NAPA auto parts store to keep your sheet nice and scratch-free. I use a nice power sander with a buffer cloth on it to give the sheet a fast going over before each project.

Here are a couple examples of my chosen solution for this (sorry they aren't B&W but just to show how this option works for my uses):

Regular glass and plexy both give the dreaded double reflection. A sure fire way to ruin a reflection shot.

There is black plexy that you can get. It is a solid color so there is no second reflection. There is also white plexy that will work for white backgrounds. There is also "milk" glass for white that is a lot more scratch resistant.

If you paint the bottom side you eliminate the whole double-reflection issue. That way you can use less costly clear plexi then paint the underside (back) any color you want with paint of the gloss you want (I prefer flat or semi-gloss as high-gloss can cause the reflections again) and you have multiple color options. Colored paper works fine as well just you might have a harder time getting a true deep black.

As for scratches, yup a total PITA, however there are easy & fast products out there to allow you to just resurface your very expensive sheets of plexi time and time again. I've been using the same sheet for over a decade and it looks brand new because I just spend 30-mins resurfacing it every now and then. A nice random orbit sander (I use one from Dewalt) with a buffer pad and some good polishes and viola you have fresh new surfaces to use.

I did some plexiglass reflection photography for my works. I got a 48"x24" Black for around $80 from eplastics. But if you don't need that big you can check on amazon. I got a few small one for under $30.

Go to Lowes or Home Depot. I get the next to thinnest and it pretty cheap. I buy the clear stuff and paint the one side black /white.

Something I've wanted to try is something I read a while back, which is to take a large shallow pan (like a cookie pan that is 1/2" or so deep), put a black cloth or maybe it was black nylon in it and fill it to the top with water. Then you place something in it that is just at the top of the water and place your object on that. Then darken the room and adjust your lights to get a mirror image that is dust free. I don't remember the details and I've been looking for information on doing this for some time. But it sounds like it wouldn't take much experimenting to get it to work.

I also like front surface mirrors, but I never knew how much dust was in my air until I started shooting on one. :D
