All this talk about corneal reflex
I haven't heard comment about the masking? Any thoughts on how they are doing
that INSIDE the camera? Not Photoshop or other editing tricks

Hasan,
Have you checked out Lester Dine Co? They used to make a small flash that just
gave a small corneal reflex. Look them up on the Interwebz.

I have been looking for a technique to capture iris images without any
artifacts for some time, experimented with ring flash, different light sources
all failed to give me such a perfect iris illumination, and saturation.
I stumbled across this video and couldn't make what is the light source used!
clearly they are not using a flash, but a continuous light source instead

Turn your guests' eyes into stunning abstract art. If you look closely, every
iris contains an incredible galaxy of colours and patterns, each more
individua...

Anyone might help what is the light source used here? or a different approach
to achieve the same result
thank you
