In time and/or being meant for photography.
well I think its all about experience, precision, passion, patient, and momentum understanding; after all of that which need time to develop, photographer will get the instinct to press the shutter.
The more you shoot the better you will be. Thanks God for digital!
I go with the theory that once you have a subject ready start shooting photos. The more repeat shots you take at different angles the better chance you have of getting the perfect shot.
By pressing it at the wrong time repeatedly.
After you make love to your camera enough times.
not sure, i guess you just 'feel' it, lol
Well, some are born with the instinct, some are not. I think you can develop the instinct through lot of practice. Practice is key.
when you feel like it just press the shutter
Lots of practice.. and knowing the shutter speed.
I don't really believe there's an instinct to be developed, it's moreso using your eyes &brain as one, &recognizing something as beautiful or interesting or unique &believing that others should should be able to view the spectacle that you see.
Shoot, review, study and shoot again. keep the cycle going.
The instinct comes with time and practice. You cant expect yourself to know these things right off the bat, it all takes time.
