I now have what I believe is the most expensive glass I have for my camera in terms of cost per unit weight of glass (I haven't weighed all my lenses).

The past few times I've gone waterfall photography shooting I've kicked myself for not bringing my neutral density filters. I have a 1 stop, 2 stop, and 3 stop 4" rectangular filter. They are good, but kind of clumsy at times.

I am familiar with the trick of stacking two polarizing filters on top of each other to use that as a variable neutral density, but the mechanical vignetting gets a bit much on several of my lenses.

Singh-Ray came out with the combination I've been waiting for. A "thin" (well thinner than other combinations) warming (I often shoot film and a bit of warmth is a good thing) variable neutral density that has two rings on it - one for the density adjustment, the other for polarization without changing the density. [link] It is a circular polarizer - to determine if a polarizer is linear or circular, look through it at a mirror through the male thread side. If the filter appears black, it is circular. If it is clear, it is linear. [link]

So, while I just missed the opportunity to shoot Burney again (see my comments about it here and here (see, I have been thinking about it for awhile)... I'll be back there in July for another shot at it.

Just another note - I tend to update my website blog a bit more often than this one... especially while I'm on trips.

On another note - the Singh-Ray blog is fun to look at and extremely tempting to spend more on... be it equipment or trips. Ohh... Australia shipwrecks... hmm...
