Need to be More Focused
Normally when diffraction comes up, most people think of light bending around a corner. But diffraction doesn’t just apply to physics, it also is relevant to photography. It plays an important part of how images end up, whether day or night, cloudy or sunny.
- Research the basics of a camera. What is aperture and what do f/2 and f/24 mean with regard to lens size and light?
- Using a dSLR or any camera that can adjust aperture, take pictures of the same object in same lighting. Try staying indoors to keep lighting constant. (For simplicity visit http://d2f29brjr0xbt3.cloudfront.net/921_diffraction/comparison2.jpg to see effects of apertures on photos) What do you notice about the image when aperture changes?
- Based on your results, why is it generally advised to mainly use apertures of f/8-f/11? What does this have to do with diffraction?
