Great colors. I don't understand the focus being centered and not keeping everything sharp, but i guess that's a preference here. I'm not even sure exactly what I'm looking at, but it's full of nice colors.
It is so difficult to photograph reflective objects without catching many unwanted reflections. But you have done it, and very well! The reflections you captured are colors, colors, colors, wow. Congratulations.
You've been able to capture many colours off your Brass. I can count at least Five. Really nice job, good focusing, nice lighting techniqiue, excellent visual interest.
Great idea! I haven't played my instrument much since highschool, I had forgotten the effect of stage lighting on the instrument. Unless you have such lighting, I'm guessing these are Christmas lights, but the effect is strong. - 10 - Mav
