In post-processing, John uses Photoshop extensively, and showed many examples of how changing the background, the saturation levels, and using different filters radically changes the creative possibilities. For instance, a small crop out of a meadow of wild flowers can be enlarged and because of the reduced resolution, the added filter produces the effect of an Impressionist painting or a modern abstract. John showed us an amazing silk scarf which was the result of one of these processes, made from an original photograph of leaves.
In the second half, John continued to share his own creative ideas for image making, using smoke, shells, kitchen utensils - many more examples can be found in his book, ‘Close-up and Macro Photography, Art and Techniques’, (see picture below). Using the range of functions available in Photoshop, especially filters and using them in combination, so that texture, blur and saturation, for instance, gives John unlimited creative possibilities. This included shrinking and stretching, cropping and flipping, and even making a corridor look as though it was an endless journey and Liverpool Street Station full of moving commuters. This was a fascinating and thought provoking presentation, pushing and blurring the boundaries of photography and art, which is often a controversial area!
