Solar eclipse pinhole camera, is longer better for a bigger image?
A 95% is solar eclipse will be visible in the UK today. I can't get viewing glasses at short notice. (eBay cancelled my order last week). If I make a pinhole viewer from a cereal box, will the orientation of the box matter. If I make it long ways, pinhole at the top projecting onto the bottom will this give a bigger image than making the hole in the side? I want to make it on the side so I have a larger space to make sure the sun hits the hole and is not obscured by my big head.
