Strobe positioning with fisheye lens

26 August 2016 - 12:59 PM

I've had my fisheye lens for about a year now, and I did anticipate a bit of a learning curve going from a rectilinear WA zoom to FE. But now I'm getting a little annoyed. My CFWAs turn out decently after a few tries to position the strobes correctly (arms tucked a bit in, strobes behind the housing and angled a bit outwards). However, I struggle to find a good position for the strobes for WA shots at a little distance. Most shots come out with very visible backscatter on the sides, like the beam of a flashlight in heavy fog.

My diving is generally in half-decent to poor-ish viz (typically 4 to 8 meters), so it might just be that the water is too murky for that kind of shots, but I'm not quite ready to give up. Tips are appreciated.

BTW, my setup is:
Olympus OM-D E-M5 in a Nauticam NA-EM5 housing, Flexitray with two handles
Panasonic 8mm/3.5 in the Nauticam 4.33" dome port
Two Inon Z240 with stock diffusers on 5" + 7" arms

Image pricing?

04 April 2016 - 10:51 PM

Today I logged in to flickr and found a mail asking about using one of my pictures for marketing since it showed a species of seaweed that one of the company's products is based on. I checked the company (pretty easy, since the email address was on the company's domain), and although I don't much believe in the product they're not running a total snake oil scheme scamming money out of poor and/or sick people. So, I don't have any serious ethical objections to them using my picture to sell stuff.
What I don't have the slightest idea about is what's "normal" pricing for this kind of stuff. From the company's domain name, it's located in the UK in case that affects pricing. I'm thinking about reserving my copyright and only allowing use for a specific purpose, with other use to be re-negotiated, so that will probably also affect the pricing.
So, given those constraints, what would be a decent price and/or starting point for haggling price?
BTW, this is the picture:

Olympus 9-18 with Nauticam 4.33"?

12 December 2015 - 01:36 PM

So, with the motivation to reduce the amount of gear to schlep on travel and vacations, I started wondering about ways to reduce the amount of camera stuff to carry. I like to switch between the Olympus 9-18 for general shooting and the Panasonic 8/3.5 FE for CFWA/WA stuff. Problem is, they require two different ports. But since Nauticam makes these nifty extension rings, I was wondering if anyone has tried the 4.33" dome, maybe with a 20 or 30mm extension ring, with the 9-18. Or will the curvature of the 4.33" dome make this a hopeless idea?


I could try, of course. But I'm not very motivated to buy at least one of those extension rings just to try it out, so it'd be nice to know if anyone has tried it.


Rabbit fish

30 November 2015 - 11:26 AM

Last weekend we did a night dive to look for the Rabbit fish (Chimaera monstrosa). It's a deep water species which you have a decent chance of seeing around here, since it for some reason likes to come up to rec depths in our waters. Particularly during late fall and particularly at night. Conditions were demanding, with lots of clay particles in the top layer and less than 1m viz at the surface. The bottom was very silty, fine clay with pebbles, so you hugging the bottom to get a good angle usually had catastrophic consequences for the local viz. To top it off, I don't have a red focus light (yet, but Christmas is right around the corner), so I struggled with hotspots from my diving light. Some of the pictures had heavy hotspots and a -3EV brush was necessary to tone them down. 


I'd appreciate feedback on a few pictures that turned out not too bad (click for the large version):













Short video from Norway

16 October 2015 - 04:07 AM

So, I'm still in the steep, very early part of the learning curve when it comes to video. I'm primarily a still photog, but since I wanted to have a little video from my dives as well, I've gone and mounted a GoPro Hero4 on top of my EM-5 rig. So far I've been shooting 2.7k30, protune, native color balance and flat tone curve to have maximum latitude for adjustments in post. Editing/post-production is in Premiere Elements 13, and I like to insert stills into the edited video.


Here's my third attempt at UW videoing and editing. It's from a weekend trip last week, to the coast of middle Norway. Any constructive feedback would be appreciated.
