I'm having difficulty with my pinhole camera that I made. When I develop the paper that I exposed (for 2 mins) the only thing that appears on the paper is the image of the hole. I have no clue what to do?
Hello Kayrode,
Welcome to the forum!
Could you describe your camera and how you use it? And post a picture of it? Otherwise it is hard to advise. And post the developed paper to give us an idea of what happened. Was it blurred or a sharp and round image of a hole?
For now it would be guessing, but it could be that:
- the pinhole is too large
- light is reflecting/bouncing inside the camera, thus blurring the image
- the photo paper was loaded backwards, thus exposing through the photo paper?
For the first problem, use the Pinhole Designer at http://www.pinhole.cz/en/pinholedesigner/ to calculate the right pinhole size.
For the second problem, paint the camera matt black on the inside of put a piece of black paper on the inside for eliminating reflections.
For the third problem, test again and mark the photo paper upfront so you know what side should face the pinhole.

These the cameras I was using and one of the photo paper that I developed.
Thanks!
