Here is a summary of all your contributions:-
1. Multicoated glasses, no direct flash
2. Angle of incidence= angle of reflection
3. Try off-cam flash
4. Contact lens with lens-less frames
(unfortunately cannot apply, requested to shoot glasses with lens)
5. CP filter
6. Curve surface will reflect at any angles( oppose against pt.2)
Multicoated glasses would help...just off track a little, what if we
were to shoot those uncles and aunties (e.g. in a wedding dinner) who
do not have multi-coated glasses and some even have magnifying glasses.
How? :dunno: They could be our important models on that big occasion.
Any more contributions?
Really hope some of you can post a photo to elaborate your expertise.
Thanks in advance.
