Tweaked, this setup can go beyond mere 8:1.Good. God. 8:1? Isn't that kind of....dangerous? I mean 2:1, fine. 4:1, you've got something to prove. 8:1 -- you're messing with fire!
But seriously -- apparently everyone knows of this macro rig but me. What lens was this that you are using?
PB-6 with reversed 28mm.
Tweaked, this setup can go beyond mere 8:1.
1. Change the 28mm to 20mm or 18mm.
2. Extend it some more with tubes (which he has).
3. Toss a 2x teleconverter in.
5. Crop and pretend.
BTW, looks like a gummi drop to me.
