I wanted a simplified version of the manual control script I wrote for Magic Lantern, so I could use the live view button on the camera to allow me to change aperture in the water, on this version I just wanted control over aperture, not ISO, so I made it a bit simpler and as a result it’s easier to use.
You can read all about the scripts I have made for manual control and back button focusing with the Canon 60D and Magic Lantern in my post on the subject here: How To – Gain Full Manual Control With A Basic Water Housing
Here’s the new, simplified script:
/** learningsurfphotography.com */
// Select duration of pause on each option in the Q menu, default is 3 seconds
@title Manual control With LV Button
@param p Pause in seconds
@range p 1 9
@default p 3
int key = wait_key();
if (key == LV)
console_hide(); // hide the script console
click(Q); // emulate pressing the Q button when LIVE VIEW button is pressed
if (key == SET) // when Set button is pressed
break; // end the script
So all it does now is simulate the Q button being pressed when you press the live view button, it stays active for about 6 seconds or until you half press the shutter, so there’s plenty of time to adjust the aperture with the top dial.
Above you’ll see a shot from the start of the session, I was using my 28mm lens and it was very early, before the sun had come up, so I needed a wide aperture to get the 1/800 shutter speed I wanted, as you can see the water in the middle distance is crisp but the surfer isn’t, a narrower aperture would of meant more of the shot in focus, which is what I was after.
This one is from nearer the end of the session, once the sun had come up I was shooting at f5 and 1/1000 of a second with a relatively low ISO chosen by the camera, when I swung around totally into the sun it was blowing out a lot of the image but these settings seemed to give me the best compromise of nice crisp shots without much noise when shooting away from the sun and usable shots when shooting towards it.
