By TibbieI have several of Bryan Peterson's books andthis is by a long shot the best one. The reason iswhile all ofthem are informative and have beautiful photos, this one tells you"HOW" to obtain the same kind of results. Then hetells you how to use the meter in the camera, how to under or overexpose intentionally, and what kinds of things can be fixed and notfixed in processing aka software. So while the other books havegreat pics and tell you what they are and what kinds of equipmentand settings were used to obtain them, this one give explicit andspecific instructions on getting tricky or difficult shots to comeout properly. Most of it involves understanding why andhowbecause when you know that, you don't need a "cookbook" toget the shot--you will know that if you don't do certain things, itwill never work.

By setting the aperture, you control how big or small the opening is and how much light reaches the sensor.

The image produced is much darker than the scene being photographed. There are an arbitrary number of pixels on the y-axis. Each shutter speed is twice downlooad fast as the previous speed. Consequently, if the small square is over to the minus side you are underexposing?

In the RGB histogram the values are averaged out for the actual red green blue colours, and are displayed as separate coloured overlays on top of one another so you can evaluate each individual colour channel.
