Hello, I am a new member of the forum, I hope I post in the right category.
I would like to discuss an idea I had last night when thinking about a comon use of Flash in photography.
(Also, I'm french, so excuse my English level, I may not have always the specific right word for each case)
I really like long exposures shot where the photographer choose to "fix" a subject with a flash, like you make a 20 or 30 sec pose at 100 or 200 ISO, and in the middle, or at the end, *puff* you fire a flash, and your subject appears clearly on the image.
What I have in mind is doing the same only with ISO manipulation.
And that's why I want to discuss it here. I have been using ML for many months now, but I've just started to look into the code and coding my own modules.
So, I wanted to know if people had already experimented this ?
Is it possible to start a long expose shot for 30" at 100 ISO, and then, in the last 1 second of the shot, taking up the ISO to 1600 for example ?
I have identified this call function :
But I still have to learn how modules are done, and of course, how ML manage tasks and how to shot a picture with it.
So the algorithm would be something like this :
[Init Module (with secondary ISO value selected from a menu)] --> [Calculate the time needed to correct exposure with the secondary ISO value]
then :
[Launch Task : shot the image (with current manual settings, like ISO 100, 30")]
and in parallel on another DryOS task with the same priority :
[Launch Timer calculated at init] --> [When the timer stops, change the ISO value with lens_set_iso ]
I think it would be a very interessant feature in ML.
Please let me know if I've done something wrong, as it is the first time I post (except for my presentation)
