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 : lens_set_iso(iso);

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)

Hello, I introduce myself, I'm kouglov.

I joined this forum because I'm interested in ML modules developpement.

I am a an engineer developper in image computation systems (computer vision with OpenCV and other frameworks)

I currently own a 6D camera loaded up with ML, wich I use for astrophotography and animal photography.

I am very interested in ISO manipulation features developpement in ML
