Even before I came across the concept of lucky imaging I felt lots of short subs is better than fewer long subs...
So check this video to hear how it is done...I have been doing 30 second subs but apparently under one second is the go
But I loved hearing the presentor say "high iso and short subs" or close to that
It is a little drawn out but worth watching all the way thru and I am sure everyone will be able to relate to "things going wrong" ....
