Nothing so fancy, just a bit of paper with an array of holes held by selotape about 40cm away from a paper pad then photo taken with phone at an angle. Did a bit of processing to darken the background. All very Heath Robinsonish ! I attached is the original. You can see the pin pricks on the pad.

Managed to capture an Ok pinhole image of the partial eclipse ..... some of the holes however were too small to be very bright.

Bradford, City of Culture 2025, looking resplendent in the spring sunshine. Mirror pool works a treat; some great Victorian architecture around easily, now pedestrianized.

A moody sky, dark storm clouds approach from the left horizon, a wooden seaside windbreak in the forefront with few feet of sand & pebbles either side meet the shore. The scattered clouds to the right hover over a dark sea, as the breaking waves are the only reflection of light. The sunset is low and pale, but enough to give some waves a fiery glow.
