Pinhole image creating

The following is a description on how pinhole images are created and then converted via Photoshop:

For a pinhole image to be taken, you must allow light from a desired scene to pass through the pinhole for a certain period of time. This time is worked out as an ‘F-stop’ which is determined by how big the box is and whether you are indoors or outdoors. The light that is projected from the area records an inverted image onto the photography film. In soft light, such as indoor common lighting, the image does not take very well. This is why a longer period of time is needed for photos to translate inside. The light from the sun is different because it travels at a much faster speed as well as illuminating much of the surrounding location. To develop pinhole images, three liquid solutions are required. The developer, stop and fixer. The developer brings through the photo, the stop is simply water which stops the developing process and the fixer fixes the image permanently to the photography film.

Photoshop editing:

Step 1: Open Photoshop.
Step 2: Click on ‘import’ from the drop down bar on ‘file’.
Step 3: Get image from the scanner in the drop down menu.
Step 4: Select the correct scanner.
Step 5: Click preview to make sure you are happy with image position.
Step 6: Select, using the cursor, the part of the image you want to keep.
Step 7: When you are happy, click scan.
Step 8: Repeat the process again but click on the invert tab before clicking scan to have the correct viewing of your photograph.
Step 9: Save image (as a JPG format) to the desired destination.
