In Topic: ALMOST Great Shots

Hi

I seem to have more of these than good shots. When night diving the problem is krill....(and shadows, and exposure, but you get the idea)

In Topic: Yet another White Balance question...

28 August 2008 - 03:22 AM

Hi

If you are shooting RAW, then you can set "cloudy" white balance, and sort it all out in Aperture or Lightroom, however I don't think RAW file format is an option on the Finepix F50, so it is probably best to shoot WB manually. I believe that this is good practice, and it is easier eventually to get it right on the camera first, anyway.

I have in the past set WB to cloudy and left the WB alone, and balanced on a slate at arms length, but currently I WB each shot.
WB on a patch of reef near you subject, take the photo, review the picture. If not the correct colours, repeat with a different patch of reef. (By far the most fiddly, but best results for me - if the picture is too red, select a pink reef patch to WB on etc..)

You really need to search the manual for your camera as well, in order to set a user definable button to carry out WB, so that balancing is quick to do rather than flicking through fiddly menus.

In Topic: Diving and Antimalarials

26 August 2008 - 11:50 AM

I think I will use mozzie deterents (but not DEET) and take the required anti-malarial drug (not Lariam) at the end of the dive trip.


HI

Everyone has this thing against DEET, but boy is it preferable to malaria (speaking as someone who has had the disease). As Drew says "DEET, treated nets and prophylactics are the WHO recommended preventative measures"

Ultrathon was mentioned, it looks weak at only 30% DEET, but it is the US Armys choice of repellent. The main trick here is that it comes as a lotion, applied all over like sunblock, and lasts 12hours (delayed release microcapsule or some such tosh) and is water resistant. I used this for two weeks in Roatan (No-see-ums territory) and didn't get one bite. On the last day, I was sitting around waiting for the ride to the airport and hadn't put any on (I was going home after all) and in 2 hours got bitten to pieces - so my trial of one proves Ultrathons effectiveness beyond doubt.

Don't dive on Larium, about 30% of people experience sleep disturbance of one type or another, this makes your judgment under stress less than perfect. More worrying if you have an underlying borderline psychiatric disorder Larium can make it manifest (remember Obsession is a psychiatric disorder - with like dive gear etc), and underwater would be a really bad place to become clinically paranoid.

As everyone says speak to the CDC / local travel clinic about what is right for you. Take the medicine AS PRESCRIBED for the DURATION PRESCRIBED (before, during and after your trip)

In Topic: Carpal Tunnel Symptoms After Carying a U/W Camera

Has anyone else experienced this? Its not reported in the medical literature that I m able to find.


Hi

Methinks that somebody is using innocent Wetpixies for data collection on a forthcoming scientific paper. Would this get through the ethics committee? :bananashark:
