I've really gotten into mixing the two but the gold fill wire is at least 4 to 5 times the price of the silver so it makes for an expensive bracelet. This particular one is a commission but I like it so may make more with different stones.
The problem with curved metal and sharp lights is the camera cannot take account of the different wavelengths coming back and therefore has difficulty in focusing on the metallic ections as thus. [link]
Occasionally one can get a sharp picture but more often than not there is a blur to metal and it's damned frustrating.
