you do not understand the difference, I can use what ever shutter speed . f-stop I want with one exposure, tell me how can you do the same with the camera on a tripod and taking 2 or more exposure. ? a example: running people in front of the camera and sunset behind, or fast running cars or what ever
1. yes, those posted images were taken only one exposure and no repeat shot
2. with tripod or without tripod, you can take hdr depending on you iso and skill, want to learn? learn yourself from jay maisel.
3. people in my picture were not my subject, therefore, i was careless. however, i consider that as a lucky thing since it is add more live to the image (imo)
sigh... i am getting tired of talking to old guy like you...
