They are useful when you are starting out, but also for the experienced photographer who needs to capture a shot fast. Familiarize yourself with these settings and get comfortable with them.
Automatic Exposure is when the camera chooses the optimum shutter speed, aperture, ISO and flash settings for your shot. This can be good if you have no idea of what settings to choose and also when you need to shoot quickly. Fill-in flash is useful in sunny conditions too, when the sun casts a harsh shadow. Macro mode is very useful for taking photographs of subjects smaller than your hand.

If you are shooting outdoors in bright sun, use ISO , or the lowest setting on the camera.
For indoor shots , somewhere in between. Choose an even higher ISO if you are working with fast-moving subjects and need to keep them sharp. Auto ISO is still an option in programmed auto. But you can gain access to settings beyond the exposure, such as white balance, metering and focus mode. Next, compose your photograph and focus with a half-press of the shutter button. Keep the shutter half-pressed.
Once you let go of the shutter button or take a photo, the camera will continue to adjust the settings if the light or scene changes. With the shutter half-pressed, check the settings that the camera has automatically selected. On most camera models, the aperture value, shutter speed, and ISO will display at the bottom or side of the viewfinder.
If these automatic settings are not quite right, use the control dial to flip through alternate options. Note that the camera may adjust both the aperture and shutter speed as you flip through the options, or just one. Continue using the control dial until you find the settings that are more appropriate than what the camera has selected. If any of the settings in the viewfinder flash, that means the photo is too bright or too dark. The camera is at the threshold and cannot adjust the settings any further.
Try turning the dial the other way, or adding more light to the scene through other methods, such as flash. With your settings dialled in, shoot the photo. Remember, once the photo is taken, the camera will re-read the scene and select a new pair of settings. You may need to adjust using the dial again.
That inconsistency is one of the drawbacks of program mode. But unlike auto, you can roll the main-dial the one near the shutter button to scroll through all the equivalent exposures which are also possible given the metering Actually I did find some information on the programming of the program mode which gave rise to my question.
If you google 'program mode program line canon' you get a link to cpn. It's just that I can't find the charts for the the mm. I've read before that the system is suppposed to try to select a shutter speed compatible with handheld shots as a start so I was pretty surprised it was so far out. I think you mis-understand the "program line". It pretty much gives you an idea of how the camera calculate aperture and shutter speed for automatic exposure if you are curious.
By knowing the line of your lens, it would not help you with anything. But if you want, you can calculate and graph it for your lens. The Canon "program line" in short says that Aperture will not be increased at least until reciporal of focal lenght is reached. At 18mm, your lens aperture is 3.
Thus, for a given scene, your 18mm f3. This is purely my speculation but I think the camera takes into account the IS on your lens.
The camera thinks that with IS enable, you can shoot handheld at 2-stop slower. The correct exposure is F5. Again this is just purely speculation. I think you are missunderstanding the Program Mode P on the dial.
