How big this fellow ?
Thanks Wisnu, my eyes are old too
About 1cm in length.
Bulakan had lots of them.
I was using Nikkor 105 with a +10 diopter at full macro focus and just moved the camera back and forth to get the focus right.
I did get several shots like this, but I want a higher wet diopter for my next trip.
The main challenge was dealing with the cold upwellings that just happen and move you off the subject. I probably spent a good 5+ mins on this one subject.
