Glass Photography is not as easy as it looks. As one very observant member at a forum, for which I'm a member, mentioned, although I thought I had all the bases covered with my photo, it still could look better! :)
Yes, and after careful examination, that person was right. The original of this photo was color and had more color streaks in it, but this Copper Version is cleaner, I think.
Really, the key to making great glass photographs is the lighting and being able to see fine details. Dust is a killer for glass photography, so be careful during the photo shoot as well as during post production. Too much glare from lights can detract from the glass's natural beauty and form.
There are more things that can go wrong, but careful planning, preparation and execution will help ensure better end results.
