Underwater Bali

[Karl]

Just back from a week of diving and underwater photography up on the north east of Bali at a place called Tulamben.

Here are some of my edits (I have about 1000 to work through )

Blue Ribbon Eel



Anemone Shrimp (I just realised it has eggs )



A Goby 'Planking' on a piece of coral

Beautiful images, all... I especially adore the 2nd one, amazing capture!

I thank you for sharing those images for the sights that most of us will never see.
A macro lens for underwater images...interesting.
Question...does AF work correctly underwater or is it manual focus?

PS, you should save one for our monthly challenge.

Excellent series......

Educational, Karl. You should create a gallery on the web and post a link to it.

Yes - I only ever use auto focus (dodgy eye sight ) and the Oly 60mm macro is an excellent lens especially with the EM-5.

I also use at time as 'macro wet lens' which screws onto the front of my housing to give extra magnification as required.

Ken - thinking about doing a website or similar one day just have to find the time

Question...does AF work correctly underwater or is it manual focus?

It does, but it's interesting how it differs below water, to above, especially when using a wide angle or fish eye lens with a dome port. It takes some people a little while to get their head around the concept.

The dome port itself offers no optical changes above water. Underwater however, it collects a wide array of light and focuses to a point behind the glass/acrylic of the dome, creating a 'virtual image'. When focusing in your view finder, the camera is actually only focusing on this virtual image inches away from the front of the lens.

Here's a bit of an article on it, if anyone wants to bore themselves:

This isn't an issue with the macro photos that Karl has posted - as he's using a flat port which doesn't distort where the light is directed, hence not creating a 'virtual image'.

Great shots by the way, Karl!!

Really nice photos. I especially like the eel and the shrimp.

Agree the Blue Ribbon Eel is a great taker

What a great set. The colours are just stunning.
