3. Soft Filter Vaseline
Need a soft focus filter in a pinch? All you need is a little bit of Vaseline (or other petroleum jelly-style product.) Just smear a very small amount over the surface of the lens, and you’ll get a very interesting, ‘vintage’ style effect. If the thought of glopping up your lenses makes your hairs stand on end, the same effect can be achieved by coating a piece of clear glass or plastic with the stuff and placing it in front of the lens for less mess!
4. Switch Up Your Medium
If you really want to get your creative juices flowing, try shooting subject matter that, as a photographer, is as-yet alien to you. Know how to capture a steaming dish of hot soup every time? Take your existing knowledge and shoot macro landscape photography instead. Always work in color? Try black and white for a stretch.
Breaking old habits is the name of the game, and finding any way of forcing your mind to think in new ways in order to achieve a great shot will have crossover benefits to your photography discipline of choice.
