Français Indonesia: Pulau Weh [Sumatra] - March 2010
I'll take you back to Pulau Weh. Under the surface, again. More than a month after my return from Indonesia, I continue to sort my photos ... Huge coral platters, delicate fans of gorgonians, colorful clouds of fish in the blue: the sites of Pulau Weh offer landscapes of beauty!
Contrary to what I initially feared, I was able to use my "standard" lens in the window provided in principle for the macro lens. According to the notice of Ikelite box for the 7Dit was not possible. But actually, if it comes in.
The only thing is that you can not use the zoom. But frankly, I'm not a fan of underwater zoom. Long live the fixed focal!
The first (beautiful) image below is not mine. But it's one of the few pictures of me under the water! ! ! Many thanks to Phil North, English photographer and videographer based in Koh Lanta, Thailand.
I love how the coral draws a pink heart, in the flash light. It's really super pretty. This picture was taken on the Canyon site.
The following are a mix of the sites of Pantee Peunateung, Meuduro, Batee Tokong ... These are my first tests with my standard lens (other than the macro, so) with the 7D under water.
It took me a while to tame the flash in this configuration. In addition, it was often in uncomfortable conditions. A lot of current, on most sites. And then, these are sites rather "deep" for those who, like me, prefer to stay within the limits of the no-decompression curve ... We find ourselves easily with a small landing of deco at the end of the dive.
But hey, that's the result. A completely different approach than the macro! And I can not wait to start again. Moreover, I feel that I will soon have to invest in a dome, with the objective "fish-eye" that goes well ...
Unfortunately, I did not manage to bring an image of the underwater arch of the fabulous Canyon. The first time, I was with my macro lens; the second time, I think that's where my goal was in manual mode (grrr); and the third time, the current too strong prevented us from reaching the famous arch.
Pity ! The place is spectacular ...
For the precise description of the various sites accessible from Pulau Weh, I refer you to the center page Lumba Lumba (in English), with which I dived.
