Adding a vacuum check system (another happy Leak Sentinel user!) was the best thing I have ever done for peace of mind.  Remember to activate every control button or lever once the light is blinking green, just in case a fault only appears once something is moved. 


Always taking a test photo (not just testing the strobes) has prevented me from forgetting about the lens cap and from leaving important bits of the system on shore more than once. 


Never cleaning o-rings or grooves with cloth or Q-tips means not having to worry about stray fibers. Foam makeup brushes and wedges are absorbent, cheap, and really effective. I use something like these, readily available at pharmacies: 



In Topic: two porcelain crabs - great color but something lacking?

Thanks Tim -


You're right about the colour, its definitely vibrant.  I remember thinking when we came across these soft corals that they were an improbable hue!  But that's how the camera saw it as these are pretty much SOOC converted to JPG by Lightroom, and other shots I took that night look fine.


I'll play around a bit with the sliders and see what happens.  In the second shot, the overhanging and out of focus polyps at the top left are quite distracting due to the white highlights but I can't think of any way to reduce their prominence without making the shot look way too artificial. 


Cheers, Robert

Excellent advice.  When I was using an Olympus zoom ring, I found that it was not always installed in exactly the right position, due to a lack of a positive mechanical locator.  It also sometimes slipped out of position if not installed perfectly perpendicular and 100% aligned with the gear.  I ended up using small bits of electrical tape as shims on the lens barrel to hold the gear more firmly in place.  It's important to be as sure as you can that the gear and ring are exactly aligned and not offset.


Although the fact that yours returns to normal at the surface does suggest something is flexing that shouldn't be!

In Topic: Feedback for photo/video setup--what would you do?

I don't know your specific video lights, but it is unlikely that two of them are "overkill".  It's hard to have too much light for video and very hard to cover an entire frame evenly with one light

In Topic: Macro lens: Olympus 60mm, or Panasonic 45mm?

Agreed on most points. But the 60 is unbeatable for really small stuff and gives a little more working distance which can be useful for lighting.

What do you mean by "focus is not great"? I find it very fast and sharp on an Olympus.
