When it comes to lighting a bottle for photography avoid using strong, harsh, direct light sources. Instead I’d recommend to use diffused lighting. Something like a large softbox over a continuous light or off-camera flash will be ideal.
The size of the softbox that you use will affect the size of the dark lines that define the shape of the glass.
For example, if you want thicker lines in the reflection, use a narrower softbox and vice versa.
When it comes to positioning your lights for glass bottle photography, I’ve found that backlighting can be very attractive. Generally speaking, backlighting is the most common lighting setup for most product photographers when working with wine bottles or any clear receptacle.
The reason for the backlighting is that it won’t create any problematic reflections or hotspots on your bottle.
This also applies to using natural light as well as flash. By having the light source behind the glass it can be more help than a hindrance.
With that said it’s sometimes useful, if you’re wanting to light up the label of a wine bottle for example, to use two lights.
Using a light in front and behind the glass bottle need to be at the same power output and both covered with diffusers.
If you are finding, there are strong reflections on the surface of the glass bottles either move the position of the light until you can’t see the reflection or double up on the diffusion by adding another panel over the light to soften the glow.
