I put a bottle of wine on the table, but was getting reflections from all around the room, so set up a few pieces of card to stop it, (but was unable to put a piece of card at the top as evident in the bottle reflections)
I took a few shots of it in ambient light, before realising to set up the cards around, the resulting image, a very plain sort of shot.
I put a light behind the card behind the bottle and it made the insides of the wine glow - I think what you see from the front of the wine bottle is an image of what is behind the bottle - like a lens. I placed the light on a chair, lighting the bottom of the cardboard more than the top, resulting in the glow from the lower portion of the background.
I did a custom white balance by putting a piece of white paper where the wine was. The card at the back was white, but I think because the light intensity falls off the further it gets from the source, the upper portion of the card is lit by the ambient light while the lower is lit by the lamps. So there's a slight gradient from white to blue - which for me, was unintentional, but a nice effect.
I placed one light behind, one on the right and one on the left, and turned them on one by one to see their effect, then tried different on/off combinations (reminds me of superposition

).
I did not have a particular image in mind, but observing the effect of each light, I iterated from the initial conditions superpositioning the effect of each light into areas that did not seem to have enough light.
Something I read about was about the relation between the size of the light and it's distance from the subject. But in this exercise I got to see it in practice. Because the translucent cardboard was a constant distance from the bottle, I'm not sure whether pulling the lights further away from the cardboard
is the same as changing the distance of the light. The size of the light source remains constant, but the amount of light from the card to the bottle changes (intensity drops by the inverse square of the distance). Should the size of the light be considered to be the amount of card illuminated through which the light passes through? I guess this does not matter too much and I shouldn't worry about it, but I was just wondering. oops, went a bit off topic, now back to it... I saw that when the light was moved further from the subject, it appeared smaller (as we'd expect) but I had a piece of card between so the size would have changed as well as the intensity. I found that I prefered the light closer, showing a large reflection on the right of the bottle.
After reviewing on the computer, I realised that I was not getting enough light at the front of the bottle - but the case where I had the lights 45 degrees to the bottle seemed to light the front well - but made the reflection at the front. Maybe I should have tried putting the label facing 45 degrees and lit that with a light on 45 degrees.
Another thing I learnt was that as I changed the light intensity (by turning off/on the different lamps and pulling them further or closer from the bottle, is that the white balance changed (as it mixed with the daylight outside). Something I did not realise at first, but learnt that I must remember for next time (you can see it in the different white balances of the photographs)
Combining the effect of each light which I liked, I ended up with this
(I added the vignetting in photoshop and still have that unpleasant reflection at the bottle neck, which I might have been able to remove if I was able to cover the top.
Another interesting learning exercise which gives me a lot to think about (thanks for the suggestions Gary), I will have another go with other objects soon.
