Yes it's a shame how tabloid Discovery and National Geographic have become. At least we still have the BBC - for now at least.

In Topic: Spot light vs snoot for macro

I can't remember - I usually use it at full power and adjust the aperture down. This tends to give the nice black backgrounds that I was looking for. You could probably use a diffuser if you wanted but unless the highlights are really blown out most things are pretty easily fixed in post.

Cheers! Do u have any screenshots of the footage shot with it that? Is 5 degrees not too narrow?



Here is a sequence of clips shot with the LF800-N. I have tried to include as many variations as possible (from above, below, from the side as well as a sort of backlight on the seahorse)

The clips have had a light grade applied to correct colour and exposure. Although the manufacturer says that the light is 5000K I found that when I set my camera to 5000K that the images were way too warm. After a bit of experimentation 3500-3800K seemed to be about right.

I have played around with a few home made snoots on my own Archon W42s (I even tried fibre optic cable inside bubble arms) but the light output was always poor.

I am now using an Inon LF800-N - It has a narrow 5 degree light beam and I have been quite happy with it.






In Topic: Panasonic GH5 first dive

07 July 2017 - 04:15 PM

Learned something new today. Using a knockoff battery with the 12-50mm lens I've determined I can only get 1.25 dives before the battery dies. So, there is a drawback to cheaper brand-x batteries and I'll changed them out after each dive when using the 12-50mm. I think the electronic zoom helps to drain the battery.


Also giving up on auto ISO. 


Is that using the power zoom on the 12-50?
