Zoom effects in DSLR

*Don't bother the focal lengths. They are inaccurate in this condition.

Original:


# Exposure Time (1 / Shutter Speed) = 32/10 second = 3.2 second
# Lens F-Number/F-Stop = 50/10 = F5
# ISO Speed Ratings = 100
# Original Date/Time = 2008:09:25 23:03:55
# Flash = n/a (8)
# Focal Length = 21/1 mm = 21 mm


After zoom-in effect:
Focus the subject first, expose for awhile, then quickly zoom in (which results the 2nd image to be bigger) and stop (to create the 2nd image) before the shutter closes.


# Exposure Time (1 / Shutter Speed) = 32/10 second = 3.2 second
# Lens F-Number/F-Stop = 50/10 = F5
# ISO Speed Ratings = 100
# Original Date/Time = 2008:09:25 23:04:05
# Flash = n/a (8)
# Focal Length = 42/1 mm = 42 mm


Zoom-out effect
Focus the subject first, expose for awhile, then quickly zoom out (which results the 2nd image to be smaller) and stop (to create the 2nd image) before the shutter closes


# Exposure Time (1 / Shutter Speed) = 10/1 second = 10 second
# Lens F-Number/F-Stop = 110/10 = F11
# ISO Speed Ratings = 100
# Original Date/Time = 2008:09:25 23:14:18
# Flash = n/a (8)
# Focal Length = 14/1 mm = 14 mm


Continuous zooming effect
Focus the subject first, expose for awhile, then quickly and continuously (to prevent the 2nd image from appearing) zooming in and out before the shutter closes



# Exposure Time (1 / Shutter Speed) = 5/1 second = 5 second
# Lens F-Number/F-Stop = 110/10 = F11
# ISO Speed Ratings = 100
# Original Date/Time = 2008:09:25 23:08:43
# Flash = n/a (8)
# Focal Length = 42/1 mm = 42 mm


Zoom-in and out effect
Focus the subject using the lens middle focal length, expose for awhile, then zoom out and stop (to create the 2nd image), zoom in and stop (to create the 3rd image)


# Exposure Time (1 / Shutter Speed) = 10/1 second = 10 second
# Lens F-Number/F-Stop = 110/10 = F11
# ISO Speed Ratings = 100
# Original Date/Time = 2008:09:25 23:17:05
# Flash = n/a (8)
# Focal Length = 32/1 mm = 32 mm
