[B-shutter Effects]

* Average
- Outputs the average value of all frames accumulated during the exposure.
- The longer the exposure -> the blurrier the moving objects & clearer the fixed background.
- Use BShutter's Average effect if you wish to take a picture of buildings, but want to remove people and cars in a crowded city, or to take a smooth-looking picture of flowing water in the valley.

* Motion
- While accumulating frames, recent frames are given more weight than past frames.
- The output will be more similar to the latest frames but the previous frames will still make an impact.
- Use BShutter's Motion effect if you wish to express moving targets more dynamically.

* Motion+
- Similar to the Motion effect, but past frames are given a little more weight during accumulation.
- The output will be more blurred compared to Motion's.
- Use BShutter's Motion+ effect if you wish to get a stronger afterimage than the Motion effect.

* Brighten
- Brightest values are accumulated during the exposure.
- Normally used when the target is lighter than the background.
- Use BShutter's Brighten effect if you wish to take a picture of a star moving in the night sky, or torch writing, or trajectory of head lights, etc.

* Darken
- Darkest values are accumulated during the exposure.
- Normally used when the target is darker than the background.
- Use BShutter's Darken effect if you wish to take a picture of the hands of a watch, etc.

* Difference
- Targets that are the most different from the first frame are accumulated.
- Normally used to take a picture of the trajectory of a target over a fixed background.
- Use BShutter's Difference effect if you wish to take a picture of the trajectory of a ball, birds, bicycle etc.
