I am experimenting with taking photos of objects placed directly on the mirror. The problem I am facing is that the reflections are showing double edges due to the thickness of the glass (3mm, the top surface is also showing some reflection)
How do I eliminate the reflection from the top surface of the mirror - any help would be appreciated

Tarique,
You might have some success using a circular polarizer. This should reduce the reflection off the glass (non-metallic) but should not affect the reflection off the (metallic) back surface.
The ultimate solution would be to use a first-surface mirror (silvered on front) but these are not commonly available and could be expensive. The front-side metallization can also be scratched easily if not coated.

Thanks - here are first results with a polarizer - much better but not enough. I guess bit more adjustment with angles of polarizer will do it
Image flipped for the heck of it ;)

Hmmm, yup, still a bit of a ghost image.
Changing the light source position may give better (or worse!) results.
Shooting at an angle close to 90 degrees to the mirror will definitely improve results. it will both greatly reduce the reflection from the front surface, and move the two reflections much closer together.

It is very difficult to do. My 6th place finish in the round challenge was on a mirror. I have been playing with the mirror ever since and have come up with some really good shots

Yeah! I know :)
Any tips would be appreciated. In your round shot (I gave it 10) how did you eliminate the thickness of the mirror?

You know I am not sure.
That is a diff. shot set up on a diff day let me know what you think. If that is good. I think it has to do with Cam angle. Of course a Mirror is actually paper glued to a piece of glass. (something of that matter) It is very hard and if you read my description It is almost not worth the Time. I think I made that point on my round shot.
