I don't know about the rest of you guys but I don't go to lake without my sun glasses.
The suns reflection off the water just kills my eyes no matter where I stand.
And there is no possible way to see into the water to see the fish because of the suns reflection.
But if I wear polarized sun glasses I can see the fish in the water, and wow what a difference it made in seeing color too.
Your camera see's reflection too.
What causes reflection, any smooth surface that comes into contact with light.
If is smooth and you have light, you have reflection.
Or lighter colored objects , like the moon reflects light to.
Not all reflection is polarized. There is also UV reflection.
For polarized reflection and UV reflection man invented filters .
Polarized filters , UV filters an ND filters. And they are used in photography.
Our pens have a smooth glass like surface with exotic wood under it,
much like trying to see fish in the water.
We need enough light to see the natural color of the fish, but we also need to see through the glassy smooth surface that is covered with reflection of light.
Called by a few different names Reflection, glare, white out , take your pick because your not going to be able to see through it or past without knowing a little science.
If the surface is smooth enough like a chrome bumper or the surface of your pen reflection is 100%/
If you move the light away the reflect gets less, if I move the light closer the reflection gets brighter It is a equal .
I was contracted to go in and work on some equipment in a open pit gypsum mine. The gypsum was pea sized white crystals, and there was no to get away from the reflection.
Which should make you think about color of back drops how many lights, how you defused the light and if you plan on filtering out polarized reflection.

It is possible to change angles in some cases. < family of angles >
Angle of light, subject and camera
It is a must that we can control angle of light to the subject.
It is also a must that we have enough light to see shape and color.
Here is the problems.
We need light but not all the reflection.
To control reflection you need polarized filters.
Polarized filers not only filter polarized rays but also the light brightness. Just like sun glasses.
So you need even more light and you are producing more reflection.
In the end you will end up with some very bright lights that have been defused and polarized.
All off this info came from the Book Light science and Magic.
This a must have information on artificial lighting.
Tools used to control reflection.
Soft light
Family of angles,
CPL or a polarized filter over your lens.
Linear polarized film over your lights.
There is a technic call Cross polarization were professional photographers photograph priceless painting and fine exotic furniture that has a glass like finish over the surface of the wood.
This is the technic I use.
It works well but it take lights that will over power the sun.
Most bright lights put out allot of heat.
If you use continuous tungsten lighting, beware they get very hot. and put out a yellowish spectrum.
And normally the professional have cooling fans on these lights
Continuous florescent lighting is some what soft because its normally used with longer shutter speeds and puts out a cool blue spectrum. Most florescent bulbs do not get hot enough to be a fire hazard.
Its best not to mix artificial lighting because of different color spectrums that different kinds of bulbs emit.
Using a Cross polarization technic is possible by using hi power flash lights with tissue and Linear polarized film over the lights and a CPL on your lens.
There is allot more to lighting and reflection but I wanted to make every aware of some of the hurtles that they face with photographing glassy wood products.
It seems like a internal struggle between enough light but not washing out your photo with glare or reflection.
