Jon Bertsch – Thalassagraphics :: Underwater Photography https://thalassagraphics.com Photography Galleries and Articles Sun, 19 Jun 2022 04:06:53 +0000 en-US hourly 1 https://wordpress.org/?v=6.5.2 An afternoon at Point Lobos https://thalassagraphics.com/blog/2018/02/19/an-afternoon-at-point-lobos/ Mon, 19 Feb 2018 23:46:10 +0000 http://thalassagraphics.com/?p=331 …]]> Over the President’s day weekend I spent an afternoon wandering part of the Point Lobos State Park enjoying the weather and getting some time outside with my photography gear. It was a bright clear afternoon and I spend some time looking for potential areas to try and play with the surf using long exposures as well as searching for some interesting features in the park.

Sunbeams over Bluefish cove

In the late afternoon the sun began to shine through the trees on the ridge above Bluefish cove giving me some interesting light as the beams hit the sea spume being thrown up from the ocean.

I hiked down to one of the different overlooks and found an area with some nice offshore rocks that added depth to the image I eventually shot focusing on the headland as it jutted out into Carmel Bay leading out towards the rocks and ocean swell. The image was set up with a neutral density filter, a polarizing filter and medium long shutter speed of 5s. I converted to black and white using Silver Efex pro and photoshop.

Headland and ocean swell

There is a nice trail system in the park that allows visitors to travel along the ocean cliffs and to visit various beaches and coves hidden around the reserve. If you spend some time exploring there are many small, interesting details to shoot so it’s worth taking your time to look around for macro images of the rocks and sand.

Rocks and headland

The park is located a few miles south of Carmel and fills up quickly on the weekends. It’s easy to hike into from highway 101 and is open from 8am to 6 or 7pm. Be careful, there’s poison oak everywhere so it’s best to stay close to the trails.

Giant Black Sea Bass https://thalassagraphics.com/blog/2015/05/21/giant-black-sea-bass/ Thu, 21 May 2015 04:27:19 +0000 http://thalassagraphics.com/?p=312 …]]> Giant sea bass - southern Channel Islands, CA
Giant sea bass – southern Channel Islands, CA

I took this image of a Black Sea Bass in the California Channel Islands. The fish was several hundred pounds and about 5ft long. He swam up to me, gave me time to take a couple of images and then took off at high speed. I was pretty lucky to get as close as I did – I was all alone at about 50ft so he was probably checking me out without feeling too threatened.

The black and white conversion was done with Nik Software’s Silver Efex Pro photoshop plugin.

Crinoid Shrimp (Periclimenes amboinensis) https://thalassagraphics.com/blog/2014/08/17/crinoid-shrimp-periclimenes-amboinensis/ Sun, 17 Aug 2014 00:44:04 +0000 http://thalassagraphics.com/?p=283 …]]> Cronoid shrimps come in a wide range of colors that match their hosts coloration. The examples here show how well their colors match. The shrimp form a commensal relationship with crinoids (Feather Stars).
Crinoids are a type of Echinderm that live on reefs around the Indo-Pacific. A number of other organisms have evolved to live on the crinoids – small crabs, fish and other critters.

Sawblade Shrimp (Tozeuma armatum) https://thalassagraphics.com/blog/2013/04/24/recent-work1/ Wed, 24 Apr 2013 16:17:13 +0000 http://thalassagraphics.com/?p=34 …]]> Following a steep sandy shore we dropped down to about 90 ft, heading out to a small group of black corals that were swaying in the current. The waters around Dumaguete where we were diving are nutrient rich and a perfect area to see healthy black corals. We were looking for the Sawblade shrimp that make these their homes and within a few moments had quickly located a large number of them on the corals. Working quickly I photographed some individuals that were living near the edges of the coral fronds before moving back up the reef and out of the current.

Tozeuma armatum is an inhabitant of the Indo-Pacific Ocean and can be found at dive sites around Indonesia and the Philippines. They live on black coral branches and have evolved to blend into the corals much like a stick-insect on land has evolved to mimic the bark of it’s host.

The shrimp can be found in a rang of colors, white, yellow, orange and have bands along their bodies to break up the coloration. They are 2-3 inches long in most cases and sit on the long fronds of black corals where they feed in the water column.
