ISO: When Shutter Speed and Aperture Are Not Enough

Detail of a spider web, photographed using an iso value of 3200.Photography is all about light. To get the exposure of our picture right, we need to balance the aperture size and shutter speed. This can become tricky in low light situations. If both aperture and shutter speed don’t suffice to get the exposure right, we can increase the ISO value. The ISO value is a measure for the sensitivity of the sensor. ISO stands for International Standards Organization. read more

Focus

Choosing the Right Aperture to Create Depth Of Field

Through selecting the range of focus in your picture, you can draw attention to the elements you want to emphasize. You can accomplish this by selecting  the focal point and by choosing the appropriate aperture size.  Understanding Depth Of Field (DOF) is a powerful creative tool. We will explain how decreasing the aperture size may compensate – to a certain degree – being out of focus. Therefore we will go through some (very) basic physics, starting with the concept of focal distance. read more
