This is Nana. In her natural state. Aboard MV Golden Dawn, on my recent trip to the Eastern Fields:

Our instructor for today...Nana
Following is Nana’s simple 3-Step Guide on how to set up your underwater camera housing.
Step 1: Do a bunch of stuff.

Hold O-ring in dainty manner while polishing shiny area

Express disapproval of rectangular thing colour

Comment on cleverness of built-in mirror

Marvel at David's vacuum pump thingy

Try to look through the housing instead of the viewfinder

When all else fails...consult Colin
Step 2: Wait patiently for Colin to set up his housing, then get him to fix everything.

Nana frustrated that Colin is taking so long...

...reverting to her natural state
Step 3: Wake up. Play with Bunny while Colin toils.

It's bunny time

Show off bunny's bear behind
Bonus Tip for Advanced Learners: Repeat daily to ensure proper camera housing maintenance.

This is Colin, looking forward to working on Nana's housing...again
