In Topic: Personal Chumming Device (PCD)

Hi Steve

I am not promoting anything, just suggesting a device that might  work under the right UW conditions, and in the hands of experienced photographers working solo.  Havent tried it with sharks (yet :crazy:  )..It did work very well with the groupers.  Its like feeding  a cookie to a dog. After a couple of dives the groupers will recognise you and will come close, even without the device. Its called 'intermittent reinforcement'. The reinforcer in this case is a weak smell stimulus, not at all like a crate containing  loads of dead fish parts.  And you can alway hide the bottle under a stone or piece of coral, if you feel uncomfortable with carrying it in your BCD pocket. On the other hand,  chumming  with bait crates might still be the best and safest method for groups of divers/photographers going out to visit sharks under supervision,

Yes, With Photoshop you could probably get rid of the knees. And..probably also the bikini top? Mermaids dont wear anything (they told me). Please forgive  me the joke. Your initiative and collection are just fine! And some people believe mermaids also had knees. See the pic of Kopenhagens mermaid.

I'm sure it meant a lot of work to get the mermaid model in the right position. But for me it was bit odd that you could still see her knees  pointing trough the tail.  (-:

With an ikelite DSLR housing you cant use fiber optic cables. But you can buy the Ikelite optic converters that transform the electrical  sync signal into an optic signal. But only for their DS strobes  See also  http://www.uwphotogr...0-strobe-review
