Photography tutorials

ISO is a measure of the sensitivity of your film or digital sensor. In this episode I discuss the basics of ISO and how it relates to exposure and noise.

In this 90 second tutorial I show how you can create a black and white image by copying the luminosity channel in LAB mode and pasting it into each individual channel in RGB mode. I find that this generally produces good black and white results from a colour image.

If you're image is too light or dark after completing this process, duplicate the layer and change the blending mode to multiply or screen and then adjust the opacity to suit your needs.

In this episode I discuss the basics of shutter speed. In the second part I'll show some photographic effects you can achieve by varying your shutter speed.

In this tutorial I show how varying your lens Aperture can affect Depth of Field (the range, from near to far, of your photograph that appears to be in focus).

In this tutorial I explain the basics about Aperture (the size of opening of your lens that lets light in).
