Lately I have seen a lot of studios offering this kind of service now. It looks a good way to make some extra money.
People use different kinds of setups and I'm trying to figure it out the best one for a better result. So far, I think a macro flash is the best option. Also, after the photo of the eye is taken, an intense photoshop edit is required to clean up the eye and ingest it in a template to achieve the final picture as this one.
What are your thoughts about it? Let's talk.
