Bimini Cat island two step

25 April 2016 - 11:23 PM

Just returned from the Bahamas where we did  Bimini and Cat island in succession. Luckily there were stil some 'hammies' left at Bimini and the end of the season. The Oceanics  of Cat island were an amazing experience. But  shooting them is pretty difficult, since you are hanging  in the blue and miss the nice sandy floor of Bimini  to kneel on. Here a stills sequence of a shark feed by Neil Watson at Bimini:  9 shots taken in 4 secs  with the D7200 and Tokina 10-17. The shark making almost a full turn.

new website

08 January 2016 - 11:19 AM


Because I had nothing better to do, I started  a website some months ago.

Primarily  to present my UW photo albums. But later I thought that it might also be a good idea  to present some  information and personal  views about the UW photography world, collected from various media and persons.These sections are mostly 'eclectic' that is,  based on pictures, ideas, notes or articles from eminent photographers that I found interesting  or useful, I also tried to keep things simple, and not to get  lnvolved in too technical issues, or  to get lost in the labyrinth of ever changing UW photography hardware So long, I am happy with the numbers of visitors, but you would also do me a  favour to give me your  ‘likes’ Thanks!

Comparing Pana 8mm 3.5f and Oly 8mm 1.8f (1)

24 September 2015 - 05:57 AM

Just received the new Olympus 8mm 1.8F FE. The  lense (which is 28 mm longer that the Panasonic 8mm 3.5 F) seems to fit nicely in my  PEN PT EP10 housing with a Zen 25 mm extension ring and the  4 inch dome (EPL5 inside). The position in the dome looks about the same as with the Pana. Without the extension I use the Panasonic 8mm 3.5 F like I did before. Sofar the topside pictures taken with these two set ups (Oly with extension and Pana without) look not so much different.Nice and crisp.
