Hi Neil
What do you think about this:
P: Programmed Auto
In the P exposure mode, the camera picks both aperture and shutter speed automatically to obtain a proper level of exposure.
For example, one reading in a dim light gives me 1/13s f/1.8 at ISO 400. When a Speedlight flash is mounted on the hotshoe or the built-in flash is popped up, the shutter speed is automatically changed to the flash shutter speed (typically 1/60s but can be changed via Custom Settings Menu). What happens to the aperture? It goes from f/1.8 to f/4. From 1/13s to 1/60s is 2 and 1/3 stop under exposure and from f/1.8 to f/4 is another 2 and 1/3 reduction in exposure. In total, the camera decided to underexpose the ambient by 4 and 2/3 stops. The flash is expected to make up the difference to bring a proper exposure to the main subject.
In another example, the camera meter reading was 1/125s f/5.6 at ISO400. When the built-in flash is popped up, the exposure changes to 1/250s f/4. There is no change to ambient exposure.
I find this in http://dptnt.com/2010/01/balancing-flash-and-ambient-exposure/
Why you dont use this type of information in your two excelent books?

Sorry Neil for my english.
My mind is techicall, I am chemical engineer, so always try to understand how the things work. In this case, I am not saying P is better than manual mode, only mention that there is an explanation more elaborate on P, than you use in the books.For me is important, may be for others persons no.
Regards
