Hi,
Nice idea to try to detect bracket shot !
3 kind of bracket exist :
bracket with aperture
bracket with time
bracket with iso ( i don't think it's a good idea to use it)
Why not try to detect bracket shot with datetime of picture and
(aperture or exposition time)
Something like :
it's a bracket if
( Time between 2 picture (need for exemple less than 2second)
And (
( Aperture Value of current picutre >= Aperture Value of previous
picture + 1 stop)
or ( Aperture Value of current picutre <= Aperture Value - 1 stop)
or ( exposition time >= exposition time +1 stop of previous picture)
or ( exposition time <= exposition time -1 stop of previous picture)
)
If we are in a bracket list of picture, previous picture need to be a
list of all picture of the bracket as usualy camera take normal picture
then +1ev then -1ev
