Glenfield Ramblers' Nature Photography
Around the same time, the technology for capturing images was becoming more accessible - both financially and practically. Before the invention of photographic technology, glass lantern slides were a popular way of keeping paintings, images, and drawings in a way that meant they could be lit up by a lantern or candle and projected against a wall. When photographs came into popular use in the mid-1800s, the positive prints of a photograph could be placed on a glass slide.
A new dry plate method was introduced in the 1880s, which meant that dry plates could be prepared in advance and did not require lots of chemicals, overly cumbersome equipment, and immediate development in a dark room. This meant that it was easier for people on their travels to document their memories. Educational sets of slides for public lectures became popular, with travel and the natural world two of the most popular themes. For the Ramblers, this also meant that highlights of their trips could be documented and later used in presentations - a precursor to the modern PowerPoint slide!
