Shutter Speed vs. Frame Rate

Define what shutter speed is and what frame rate is. What is frame rates relationship with shutter speed?  How do each affect the image? How could you use these principles to artistically affect your images going forward?

    Shutter speed is the duration of time each individual frame is exposed to light. Lower shutter speeds creates more motion blur and higher shutter speeds make crisper images when paused. Additionally, the different shutter speeds also affect the exposure, higher shutter speeds having lower exposure. Frame rate is how many frames are captured in a second. The standard in film is 23.98, or more commonly known as 24p, as film used to be more expensive thus making it costly and excessive to shoot at higher frame rates. We've maintained this standard as it's come to be known for having a cinematic look; additionally, higher frame rates causes a loss of motion blur, which often doesn't look right in films. That being said, you can record at higher frame rates then put it back into 24p in order to create a slow motion effect. The relationship between frame rates and shutter speed is primarily how it affect the way motion looks on the image. A good rule of thumb to capture a cinematic look is to have your shutter speed double your frame rate, i.e., 24p at 1/48 and 30p at 1/60. Having your shutter speed be slower and faster than double your frame rate can create an unnatural looking image. This can be applied artistically in order to help amplify different emotions and create different looks. For instance, if I want to unsettle the audience, I could use a different shutter speed to make something's motion look unnatural. I could also use the higher frame rates to create a smooth slow motion, or the same frame rate to create a choppier look.
