When a script makes exposures with the shoot method, how are ISO, aperture and shutter speed set? Can I put the camera in Av mode (Tv mode), set an aperture (exposure time) and then start the script and whenever the shoot method is called in the script it will use the aperture that I set?
How does the camera define the focus when the shoot method is called in a script? When calling the shoot method from a loop, will the focus be exactly the same each time the method is called?
Can I calculate exposure values (EV) with different metering? Say, I want to create a EV bracketing series of six pictures by "spot" measuring the darkest and brightest spot in a scene. Taking the brightest spot I want to bracket with constant aperture by EV 3.5, taking the darkest spot, I want to bracket by EV 1.5. Would that be possible?
When writing LUA scripts on my Mac, how do I have to save the scripts? Which encoding and line feeds should I choose?
See above - focusing is done by the shoot command by emulating half-pressing the shutter button
x = 0press( "shoot_half" )get_focus( x ) release( "shoot_half" )
press( "shoot_half" )set_focus( x )press( "shoot_full" )
Thanks for the answers. I have one more question regarding the focus. Say I want to store the focus in a variable like this:Code: (lua) [Select]x = 0press( "shoot_half" )get_focus( x ) release( "shoot_half" )
press("shoot_half") repeat sleep(10) until get_shooting() == true... get your values here
For what you describe with focus, you may want to use canons own AF lock feature, as described in the canon manual, but using emulated button presses.
-- get the focus and lock it (works only on S models, see S5 manual AF Lock for example)press( "shoot_half" ) click( "mf" )release( "shoot_half")-- subsequent shots should now be made with this lens focus-- ... taking a lot of shots here like thispress( "shoot_half" )press( "shoot_full" )-- release the AF Lockclick( "mf" )
Code: [Select]-- get the focus and lock it (works only on S models, see S5 manual AF Lock for example)press( "shoot_half" ) click( "mf" )release( "shoot_half")-- subsequent shots should now be made with this lens focus
-- get the focus and lock it (works only on S models, see S5 manual AF Lock for example)press( "shoot_half" ) click( "mf" )release( "shoot_half")-- subsequent shots should now be made with this lens focus
