HI

i am a student,i have some doubts in film and digital cameras.

In film shutter speed or frame speed is same right but shutter angle is different,i am clear about this thing

In digital cameras shutter speed and frame speed is different,if u increase shutter speed motion blur comes,frame speed u can increase or decrease along with shutter angle to compensate exposure...

Well shutter speed is directly dependent on shutter angle. If you set your camera to 25fps (shutter angle 180° which is normal) you will be getting 1/50th of a second exposure. Increasing the exposure will give you less motion blur and espcially video will tend to strobe due to that fact and the nature of most CCD sensors. Film is somehow more forgiving up tp a certain point. i.e. Setting the shutter angle to 90° means you reduce exposure to 1/100th of a second. The image becomes sharper and has less motion blur.

There is lots of information on the web and I would recommend buying the American Cinematographer Manual for these kind of questions. Understand that this is basic knowledge and you must be failsafe when shooting or risk to make wrong decisions technically.

Shoot safe.
