1: Full colour control

This first section has 8 projects and Assignment 1. The projects are:

Project 1: dynamic range
Project 2: understanding the histogram
Project 3: a variety of lighting conditions
Project 4: your camera's colour performance
Project 5: a personal range of colours
Project 6: measuring colour
Project 7: altering colour with levels
Project 8: altering colour with hue/saturation.

Assignment 1: seasonal colour changes.

It is interesting to note that digital photography gives more control over the colour in a photograph than film. In this first section I am being asked to take into consideration brightness and contrast, using both the camera settings and the full range of editing tools when enhancing and altering.

Dynamic range was covered in DPP but this first project looks at it in more depth, it helps to know the relationship between brightness and f-stops, the normal sequence on cameras is as follows f2, f2.8, f4, f5.6, f8, f11, f16, f22. Using the camera's inbuilt light meter you can measure the brightness of different areas of a scene. I know that doubling or halving makes a difference of 1 stop but it still confuses me when I have to put it into practice, it is something I have to think about rather than it coming naturally! Hopefully with more practical work this will sink in!  A suggestion is to try and work out if you can judge by eye the mid tone in a scene....

experiment to be done...
