Yongnuo OC-E3a TTL Cable
I recently purchased a Yongnuo OC-E3a Canon TTL flash cable from
Deal Extreme (an online store based in Hong Kong)
for just USD$24.86, with free shipping.
The Yongnuo OC-E3a cable is less than one third of the cost of a
genuine Canon OC-E3 cable, which retails for
USD$69.95.
When Do You Need a TTL Flash Cable?
A TTL flash cable allows you to get your flash off your camera's hot shoe, while still maintaining full ETTL communications
with the flash.
This can be useful when using a flash bracket or light-stand to hold the flash, or even when using one hand to hold the
flash away from the camera body.
It's not limited for use with flashes - you can use a TTL cable for mounting a Canon ST-E2 wireless transmitter
remotely from the camera.
This can be handy if you are using the ST-E2 to control one or more remote flashes
wirelessly, but where the flashes are outside the forward-pointing optical transmission of the ST-E2
(ie, the flashes might be to the side, or even behind the camera, and without sufficient reflective surfaces
to bounce the infrared signal from the ST-E2 to the remote flashes).
Yongnuo OC-E3a TTL Flash Cable
The Yongnuo cable is a clone of the genuine Canon OC-E3 TTL flash cable, but is significantly cheaper than the
genuine article from Canon.

The old oil tanks at Albany's Whale World,
which have been converted into mini movie theatres. Each of the movie theatres
has a different short movie about the whaling station.

Canon ST-E2 Wireless Flash Transmitter
Overview
The Canon ST-E2 is Canon's dedicated wireless flash transmitter,
designed to be mounted on a camera's hot-shoe, and can trigger one or more Canon flashes wirelessly in E-TTL mode.
When mounted on a camera's hot-shoe, the Canon 580EX and 580EX II flashes can also be used as a master device for
triggering and controlling multiple remote Canon flashes in E-TTL mode.
However, there are a number of differences in functionality between using a
580EX / 580EX II as a master, and using the ST-E2 as a master device,
with advantages and disadvantages for both options.
The tables below summarise the differences between using a Canon ST-E2 or a Canon 580EX / 580EX II as a master flash trigger,
with differences highlighted using a different background colour.
Details were sourced from Canon's technical specifications and user manuals, as well as the results of
my own testing with the ST-E2 and 580EX II.

Here's another one from a sunset shoot last week at North Beach.
The colours in this particular photo were not very inspiring, but a black and white conversion
provides a more striking result.

Yesterday evening, I met up with some fellow photographers at North Beach,
to shoot the sunset from the beach, using the rocks to provide some foreground interest.
Here's a long exposure, taken about 30 minutes after sunset
(click the image to view a larger version).

The
Department of Environment and Conservation
are using one of my photos (with permission) on a new sign at the Mangrove Bay bird-hide in the
Cape Range National Park,
near Exmouth,
in the north-west of Western Australia.
The photo being used is a white-faced heron
that I photographed at Sepentine Falls a few years ago.
If you're ever Mangrove Bay, be sure to check out the sign!
