Need help on this pinhole photography. I have made a pinhole camera at home using Oat meal tin. Body: Oat meal tin Lens (Hole) : #14 pin Film: Ilford Multigrade IV Deluxe MGD.44M 5x7-25 Sheets B&W Variable Contrast RC (Resin Coated) Pearl Paper Exposed for: 20 sec. Result: I tried a picture today around 10am with sun light as my daughter as subject sitting in front of a wall. When I developed this paper tonight I got some kinda Black with bit of white textured paper and nothing else is visible. Whats wrong? Is it over exposed or under exposed. Why could I not see any sense of image in there? I need to try for tomorrow again. Any clue would be highly appreciated. Thanks Elangs.
