We had great fun today creating a camera obscura in the photography room. We blacked out the room (as best we could) and cut a small hole in the material over one window. We hung a white sheet opposite and hoped for the best. After about a minute our eyes adjusted to the gloom and we could clearly see an upside down image of the building opposite projected on the sheet. We used a 30 second exposure (ISO 3200) to capture this image.

To obtain an even clearer image we held a piece of white card close to the hole. We then decided to cover the card with photographic paper and experimented with various exposure times to capture a paper negative image (as you would in a smaller pinhole camera). I’m looking forward to making the positives tomorrow in the darkroom.

Watch this space!
