I jus got an assignment by my friends to shoot some crystals that he had bought. those coloured stones cut like diamond (i know nuts abt stones)
he wants those sparkles on stones(like those in magazines), so i was thinking of using those star filers to shoot with those strong spot lights. Will i attain that desired effect? I tried stopping down the aperature, but was quite insignificant.
If i am to get a star filter which type should i get? a star 4, 6, 8, 16 or other types?
