S40, DC300 - Using the four-way controller

Recommended Posts

Hi

 

I have just added a YS90auto to my set-up without much success. I used the auto aperture or auto shutter speed, but the first gave me backscatter and the second not enough light. Looking through the forums i came across a link to a thread that showed how to be able to use the 4-way controller when in the housing, but unfortunately the link only lead back to the forums home page.

 

I didn't think it was possible to use the 4-way controller underwater, but if it is can anyone explain how.

 

Thanks

Steve

With the S30/40 you can use only the speed. To change the aperture, you have to move to Av, select the F number and return to M.

With the S45/50 you can change the aperture by click on the [0] button (the one at the button / left. see link from canon.co.jp

Steve,

 

Not sure if I'm answering your actual question or not...

 

With the S series cameras, S30 and above, you can use the up/down four-way controller in the menus by holding down the MF button and using the right/left buttons.

 

I use my S30 this way underwater to adjust ISO.

Because it’s so uncomfortable to use the controller in M mode I usually use the aperture priority or the speed priority according to the situation and what I want to shoot.

Experience!

 

Give you self an quarter hour time during a dive to test around and you will get a pretty good feeling. Thats what instant feedback is for.

 

I don't think there is a real teachable rule of thumbs on strobe settings.

 

Maybe something like: more macro lower setting; more WA higher setting

What I done was: first took some shots on land for few situations: macro (10cm), 1/2 m and 1m and wrote the values of the F number and the strobe adjustments.

Then I subtracted -2 stops as startup values and wrote in on the slide. And then I went to the water with the startup values and began to shoot and make corrections until I found the best values for every situation and wrote it on the slide.

So now I have a startups values but it’s only for start because every time it’s a different situation. You have to test it every time until you began to 'fill' the right settings.

Another thing, use the histogram in the camera, its gives great information.
