#368093 Weaker+stronger strobe in pair?

Posted by errbrr on 08 December 2015 - 07:37 PM

I often use one Z240 on full power and the second on 3/4 power. I like the 3D effect of slightly more shadows from one direction while shooting wide angle. I use the stronger one as main light and the weaker one as side fill, or aim the stronger at the background and the weaker at a close-up subject.

#367883 Strobes versus Video Lights

Posted by errbrr on 03 December 2015 - 08:47 PM

I recall a story from Alberto Nava's talk about shooting in Hoyo Negro with Nat Geo. They were keen on lighting things with constant light instead of strobes, so the team ran a large amount of cabling through the cave to hook up a 3 phase generator to run topside in the jungle. The photos are nice, so I guess it worked.

While I think I could justify to my Dad that I have borrowed it (given he hasn't used his Nik Vs in a few years), justifying sending it to the States might be a little harder. Your offer is otherwise excellent :-)

#364636 Using nalgene or latched acrylic jar to put your non-waterproof torch?

Without the camera, how would you capture scenes of enthusiasm like this? On mobile otherwise I'd post the photo itself, sorry.


#361966 another strobe or 105mm

Posted by errbrr on 08 June 2015 - 07:47 PM

If you prefer wide angle shooting, go the second strobe. If you prefer macro, go the lens. 


Wide angle can be challenging around here but when the visibility delivers (or if you like the wrecks or the caves) it's the only way to go.

#361492 Why do you shoot underwater?

Posted by errbrr on 25 May 2015 - 07:11 PM

Awesome photos Tim.


Perhaps it reflects the diving I'm doing at the moment, but I find that I'm shooting to tell the story of the dive trip. Which means not just the underwater pretty shots, but also the getting in/getting out images, and getting prepared images, and all the bits that go with it. The shots of sea lions playing underwater that I took on the weekend are nice, but having the shot of the boat we got there on, and going snorkelling to get the shot of the sea lions hauling out when they got bored, and the shot of them harassing divers underwater for fun - all those images are part of communicating the experience of diving with sea lions.


I'm definitely driven by sharing what I'm taken. As well as showing what we saw when we got there, I want to show how we did the dives, the effort that went in, and the fun that was had between times. To tell the story to those who may not have the chance to experience the same.

#357294 Full Frame SLR wide angle corrector port tests

Posted by errbrr on 31 January 2015 - 06:23 PM

Thanks for the explanation of the components Alex - I studied the housing photos you posted earlier but wasn't able to spot the difference. I am very interested in something similar with my rig based on those results you are posting. I currently shoot the Canon 14mm full frame in the caves behind an 8" dome and rarely dip below f8 because the rocks go all fuzzy around the edges. Even at f8 or f9, close up rocks give an irritatingly fuzzy foreground. A bigger dome is not feasible as it may not fit through the restrictions. Your setup would solve that problem very nicely.


The 14mm lens doesn't however take a filter as the front element is not flat - would it still work? Maybe with a little duct tape on top of the blu-tac...

#348726 Best system setup for cave and wide angle photography

Posted by errbrr on 05 June 2014 - 04:05 PM

I agree with the lighting comments - spend your cash on the strobes (I use inon Z240s because they are small) and the triggers for them (Hedwig can help you out with triggerfish). One on camera and one off camera is a good start, two on and two off is even better. More than that takes a bit of practice to co-ordinate.


For the camera, go as wide angle as you can for caves. I use a dSLR and know nothing about m4/3 so can't help you out there. Good luck with your shopping!

#347220 Cave diving, rebreathers & restrictions

Posted by errbrr on 03 May 2014 - 05:02 PM

I was out in the Nullarbor caves over Easter, shooting for a client. Once we were done with work my buddy and I headed off to a different cave to get a few dives in. The video from one dive is below. It was half shot with my Canon 5DII, half with my buddy's GoPro. He's the diver in black, I'm the diver in yellow. If I'm in the shot without the camera, my buddy is getting to grips with his first go at a dSLR. He had a good crack at keeping it steady!


Olwolgin Cave is characterised by stunning rock formations and haloclines in the water, so I needed to shoot through water that hadn't been swum through yet. Most of the shots are pushing the camera forward slightly to prevent the fuzzy water from enveloping the dome port. 



Here are a couple of shots taken of the same cave system, both on the breathers and on the subsequent dive in sidemounts. You can see the stirred-up halocline water under my knees in the first shot.





#343953 Where/how do you stow the neoprene dome cover?

Posted by errbrr on 28 February 2014 - 10:28 PM

Clip it to yourself, not your camera. Mine lives on my right hip D-ring. If the cave is small and it's dragging against the roof I put it in the drysuit pocket instead. Alternatively clip to a hip D-ring and then tuck under your waist band - works well for me in the tropics with no pockets.

#343951 Darwin's Dream - Galapagos

Posted by errbrr on 28 February 2014 - 10:06 PM

The iguanas are awesome, and the orcas are incredible. Are they normal for a Galapagos trip? Also not a single bubble trail or flappy diver through your shots, very nice.

#340648 Your Favourite/Best Image of 2013

Posted by errbrr on 14 December 2013 - 09:58 PM

Great shots, one and all.


We have done 10 trips into this mostly "dry" passage cave this year, and I discovered the way out of a sump and 130m of passage in the sump beyond. I also dragged my Aquatica housed 5DII 2kms to the end and 2kms back back again on 7 of the 10 trips. This shot is my favourite - these early sumps are just 15m long and you only get one chance before it all silts out!




And this shot is from caves in Indonesia, one of the best dives I've done. Nearly 1km in I certainly wasn't expected stalactites. These decorations were awesome and topped off a brilliant dive. 2013 has been a great year of cave diving...here's to 2014!



#337563 Housing rinsing techniques

Posted by errbrr on 28 September 2013 - 05:08 AM

When I dive in freshwater, which is most of the time, I don't rinse. Although if I've managed to coat the thing in mud as well it's more of a spray rinse then soak to try and get it all off. When diving in salt water I like to dunk at the end of the day and usually work the buttons a bit too.


I don't leave my housing unattended in rinse tanks if there are other people around. And if I want to leave it in for an extended soak I usually remove the camera first, which means I'm already home and the soaking is happening in my bathtub.

#336546 Using Sea & Sea YS-D1 strobe for land use?

Posted by errbrr on 02 September 2013 - 03:43 AM

I burnt out a few tubes in my inon Z240s doing this. Take it slow and consider having a bucket of water to dunk them in occasionally.

#330631 Boat Water Entry with Camera Gear Methods

Posted by errbrr on 30 April 2013 - 09:57 PM

In rough seas around here I much prefer to giant stride with my DSLR. Trying to get close enough to grab a camera from a large boat that's slamming back into the water with every wave is not safe. I wear a drysuit and stiff fins and find I can control my jump....by the time the water's up to my chin, I'm not moving very fast so my camera rig hits the water gently. No disasters as yet.

I have backward rolled too, that takes a bit more practise with an 8" dome. Most fun of all is an abseil down into water with the camera swinging under you. I love cave diving! I also take my neoprene dome cover with me on every dive.
