ISO: It's Important
Sometimes the use of dappled sunlight is just the effect a photograph needs. Dappled sunlight can make an image feel more relaxed to the viewer. It can also give an appearance of spontaneity. Because I did not use any artificial fill-light I had to use a higher ISO*. I chose to set my ISO to 1000 to compensate for the lower light levels. Basically ISO represents a value of sensitivity to light that a camera’s digital image sensor processes into an image. The lower the ISO number the less sensitive to light and the higher the number the more sensitive to light. Please note that a higher ISO level can increase the noise (grain) in your image. Sometimes noise can be a very desirable effect. In photography, you must have a comprehensive understanding of three important and interlaced functions.  These functions are shutter speed, aperture and ISO. Today I briefly touched on ISO. If you understand and control these function, then you can control the outcome of your image. Among the most important things I can leave you with is READ YOUR MANUALS. Understand every function, button, knob and icon on your equipment and most importantly how they affect each other and your results. Photography is an art and a science. These are the steps that will begin to separate you from just taking pictures to creating photographs.
