I don’t have to present any proof, do I?
This was taken with a 1/2 hour exposure using the 0.18 mm pinhole and a 50 mm focal length on a Zero Image 45 camera. This is expired gold border color film. This picture was enhanced by the Photo app on a MacBookPro. The original is below. This is my Yamaha C7 Piano. I rested it on the corner of the instrument while I practiced. The overexposed area up to the left is the piano light . You can make out the strings, the lid, and the music stand. The original is below it.
