Is there anyone else bought the new Olympus 790sw. 

How are you getting on with it??    Have you worked out the best setting to have it on whilst taking pictures underground.

There are that many different settings i cant seem to work out the best one. 

Any advice anyone???

Hi I have the Olympus 720sw which takes excellent photos underground when used with a firefly3 and remote flashgun, but for formations or anything not moving then I use the nighttime mode as this gives you a 4 second exposure which is enough time to fire a flashgun using the test button producing side lighting which always improves your image.

I have the Olympus 790sw and am very happy with it. Its main function for me to survive the riggers of the underground and its doing that very nicely, its been in swildons, caked in mud dragged, poped in my oversuit and then I crawl on it and after all that you simply pop it under water to clean it off! very pleased. Like ogofmole I found the 'night scene' mode gives about 4 sec exposure which can be enough to do some very quick light painting or give you time to manually fire a flash. Sadly I cant get it to fire just a single flash to set off a second flash with a sensor but thats not a bad thing as using the built in flash which is very close to the lens (recessed and protected  (y) ) gives you steamy looking pictures. Here is a couple of recent caving trip reports with pictures taken by my 790sw.

- White Pit Cave - some 4sec exposure lighting with scurion. / Some flash in 4sec delay. 1st time using a mini tripod.

- Hunters Inn Sink - some 4sec exposure lighting with scurion, just balanced it on rocks.

Pictures are not amazing if you compare it to lugging around an SLR with multiple flashed and tripod etc etc but unless your on a 'photo trip' who wants to lugg all that about for every trip!

Camera is thin and can hang from neck tucked under over suit and I confidently crawl on it and do squeezes with it.

Just another thing that I forgot to say, when using this camera underground. Turn off the standard Auto ISO and set it to 64 or 100 otherwise you will get grainy photos with lots of digital noise in the dark areas.
As c**tplaces said the on board flash  is very close to the lens so I cover it in exposed 35mm film so that only Infrared light gets through to fire the firefly 3 slave unit.
