#345326 corrosion on Solo lights

Posted by bvanant on 30 March 2014 - 12:34 PM

I think that L&M decided to not put any type of capacitor in the charging circuit at least on the early versions, and both terminals have major corrosion on some of my lights. On the L&M page they say

How to remove contact corrosion:

You can make our own cleaning solution by mixing a few drops of 25% vinegar / 75% water. With a small amount of this mixture and small piece of fine steel wool, you can gently remove corrosion and get these battery contacts shining like new!

What is the best way to dry my Sola?

After you have rinsed thoroughly, it is also extremely helpful to dry the light off. Residual water droplets can lurk inside the small space of the charge contacts and cause corrosion.



#343198 Selective lighting

Posted by bvanant on 11 February 2014 - 09:14 AM

I have my wife dive with an off camera strobe with a Retra LSD attached that is triggered by a Triggerfish sensor.  She aims the Retra at my subject.  That way I can concentrate on camera settings and composition, while she maintains proper aim of the snoot light.  It gives her a way to participate.

My wife carries a video camera and my participation is to take photos of the cool things she finds after she is done and to make sure that I don't allow any strobe flashes to show up in her video clips. But because she has all the talent in the family it works OK.

Yes indeed the menus are fun, but there is a post in the OLY thread about "preferred settings", once you get them down, you should be good to go. Make sure you take the manual or a PDF of it on the trip.

Unbelievable. Somehow we need to stop the demand, fisherman will fish for anything they can sell.


#342198 Why are there so few housing / strobe combo with hotshoe connection?

Posted by bvanant on 21 January 2014 - 09:56 AM

Digital TTL is quite different than film TTL. The technology of film TTL (at least Nikon's version) was simple to implement via a simple connection. Modern eTTL and iTTl are very different with much of the electronic bits in the flash, not in the camera. If you are willing to house a name brand strobe then getting true eTTL or iTTl is quite simple but Nikon and Canon (correctly, I think) consider their TTL protocols as proprietary.  That is why there are converters (Matthias) and sTTL emulations of TTL.



#342196 Is there a place for Instagram-esque post processing in UW photography?

Posted by bvanant on 21 January 2014 - 09:48 AM

Personally, I like the sepia one a lot more probably because it looks a lot less like the 10,000 other hammerhead photos out there. Good job I think.


#341683 Mirrorless Forum?

Many folks shoot both, but I think having two fora/forums will be quite useful.


#339065 displaying photos for sale at show?

Posted by bvanant on 05 November 2013 - 06:34 PM

A simple hinge for hooking the two mat boards together and linen tape to the back of the photo to attach to the  back mat. Golden State art sells both uncut and precut and sells the plastic bags too (pretty low end but probably good enough for the show). 


#326781 Understanding D7000 and Inon Z240 Settings

Posted by bvanant on 26 February 2013 - 09:45 AM

Yes set the internal strobe to manual and 1/128 power. Should be no problem with the Inons.

In the states it is $1.55 per meter or $350 for 500 meters if you have lots of friends.

#321856 Best EVIL camera for underwater use?

Posted by bvanant on 02 December 2012 - 12:34 PM

Any of the NEX or micro 4/3 cameras can be great underwater but if you shoot strobes and a focus light they are not all that much smaller than a DSLR rig by the time you have the arms and batteries and chargers etc.

I have had better luck with the dry heat (the sausages notwithstanding) but I have access to an annealing oven that can control temp quite well. If you do it in water I get best results starting in cold water then heating it up slowly to 95C or so then cooling slowly rather than dip and dunk in already boiling water. Make your mandrel about half the size that you want the ultimate coil to be.Bill

Why don't you download both and play with them for a month. Then you will know what suits you best.

#316905 SANYO ENELOOP XX Batteries? Anybody using them?

Posted by bvanant on 21 September 2012 - 05:24 PM

They test out quite nicely compared to normal eneloops (the 2000 mAh ones) and if they start to not charge properly, try running them through the LaCrosse type charger on a refresh cycle. I haven't had to do that with the XX versions yet but with the older style the refresh cycle takes them from 1700 mAh (after a few hundred charge cycles) back to 2000 or so.

#316904 Little micro strobe batch!

Posted by bvanant on 21 September 2012 - 05:22 PM

There have been a number of Canon flash converters available (Ike, Heinrich's, S&S etc.) so I don't think that is the problem. The problem will be to emulate the electrical signals and turn them into an optical signal. Notoriously hard to do with LED output (quenching them for low power is tough) but I remain hopeful.
