imagine a thin slice from the middle of a photo then keep taking that photo again and again putting the strips side by side you end up with horizontal stripes
,then something gets in the way of the photo the stripe configuration changes,
the film is constantly moving,if something goes past the slit at the same speed as the film is moving it appears as normal in the photo but with a stripey background.
another interesting effect is the way that objects traveling in either direction will always go the same direction as the films movement.
thirdly if say a car puts its nose across the slit then reverses back without fully crossing,the result is a car with two noses.
so there are several slit camera designs about,http://www.flickr.com/photos/limerick37/6931440568/ as im not really into programming, my design will not be using any, iv also tried to keep the maths to a minimum, i did some maths to work out what effective shutter speeds iv got, this test image was done before i did the math.
most of this i already had
bluetooth device(4printer) pogo printer or label making stuff,
battery drill,step bit.
hot glue gun,
epoxy fast rapid and strong............ £5
thin scrap metal
motor regulator............. £15?
led running light............. £7
eyelets and setter................,£5
round nose pliers(open camera)
batterys and holder.............,£5
broken camera ...................£2.2
polishing paste and pad
dremel style tool
small metal boxes (torch and tobacco tins)............£3
Step 1: My prep to keep it simple
Step 2: Follow them there lights
Step 3: Rev it up
Step 4: Take your pick
Step 5: Smash it up,gently now
Step 6: Does my crack show
Step 7: I love it when they flash
Step 8: Strapped up and covered in sticky stuff
Step 9: Fill it hard
Step 10: Make the hole bigger
Step 11: Motor knob
Step 12: First public exposure
Step 13: Assessing the damage
exposure somewhere in the middle
daytime overcast outside
i forgot to cover lens whilst rewinding
film got caught halfway through, i think on the rough slit
Step 14: The more friction the shinier itll get
Step 15: Counting orbits
8 teeth on sprocket gear ,
8 sprocket holes is 33 mm of film.
the slit is 0.68mm .
33 divided by 0.68 is 48.52941176
one turn of the sprocket gear is about 48.5 exposures
so if one revolution takes 2 seconds
2 divided by 48.5 is 0.0412371134 second exposure
OR 48.5 divided 2 is 24.25 which in camera time is 1/24
i was measuring the time for 10 revolutions and multiplying the length of film by 10 , this makes the values i get averages of 10 soo less error
did the same with the lights and wrote the numbers by the knobs at where they were set
