OK while not anywhere near Tupperware's friend's league I made some improvements for a second beer shoot today.
I added a third light source (now lit left, top and right, with the right light source being new) and changed from my 50mm 1.4 lens to my 70-200 4L which I believe captures color better. I also added a polarizing filter to get rid of the reflection on the front of the glass. Note the light box is open front, tissue paper walls left, right, ceiling, and I've got a piece of white poster board taped to the rear wall, curving down to the floor. I'm shooting the glass with the logo to the rear as a measure of the clarity of the beer.
While I think this is real progress, I am now wondering what to do about the shadow reflections in the back of the glass. Do I need a bright light source behind the camera? Can I get away with using an on camera 430EX for that?
Or is it possible I can fix it with further adjustment of the polarizer?
Tupperware any chance you can get your friend to look at my amateur efforts?
I am not doing this for product advertising but looking to use these as a permenant record for my brewers log. So as boring as these are I like the predictability and repeatability of the technique of using the box. If I can't do any better than this I am still pretty happy with what I've got.
