This is a HARD shot to do well - but your instinct is in the right direction.

I would have not have kept the window in this shot as it's a distraction.

You worked with what you had and this looks like a product shot. For such a shot more lighting control would be needed from additional light sources and/or reflectors.

Your eye is good however and lighting the bottle from behind is a great way to do this. The edge light is also nice. You can't read all the letters and see all of the bottle's details which is essential for a product shot and that's where the additional lights were needed.

This was a good try though especially since it was in such a non controlled (not a studio) environment.

Hope that helps,

Marko
