EJ, I would love to know more about the scene depicted. The male and female have the "sun glows" around their heads which implies deity. Yet, they are in a pose for a wedding. If this is Jesus and Mary, then I would like to know more about the pose. Just my ignorance seeking knowledge. Your capture of it is, as always, excellent.
needs to be sharper. If the stained glass was your work it would be ok but if you take a pic of someone else's then the pic should be a good quality one.
The heads and halos are one piece of glass
of a light tint,which gets fired 3 times.Silverstain is painted on it and fired in a kiln which turns that area yellow/amber.
The line detail is painted with a glass paint[powdered glass in a medium] which is fired at a different temp to the silverstain.
additional shading is obtained by painting over the line work,
this is fired at a lower temperature than the line work.
Very good shots,a tricky task photographing stained glass.
