the camera

The pin hole camera has a shutter just like the SLR , except that SLR is more advanced . the SLR has a delayed shutter realease an aperure setting ring foucusing ring and an iris diaphrame ... and the pinhole camera is less complicated. they both project a picture though the shutter that allows light to project a picture. The SLR camera controlls the light that goes through many passages before it makes a pic , it happens so fast that u are able to freez exactly perfect at that split secound. The pinhole u have to be more precise and carfule to get a good picture other wise the picture would come out to dark or to light.
