A610 shooting modes explanation needed

[mkrzych]

Hello,
I have Canon A610 digital camera. I've read the manual and can anybody explain me in what situation I should use AE/FE lock in practice? I'm rather new in digital photography. Examples will be very usefull, because I don't understand what common situation need lock flash exposure setting and what's the diffrence with manual settings and combinations of shutter speeds and aperture values without altering the exposure in AE lock mode.

Greetings,

Normally Auto Exposure Lock is for situations where you want to meter off of a specific item. You can zoom in, get the proper settings, "Lock" them into place, zoom back out and take a picture and the entire scene will be exposed off of that specific item.
Below are some examples I took from http://www.cambridgeincolour.com (these photographs were not taken by me):

In this example (above) the photographer metered off of the light comming through the window, and as you can see, it produces a very pleasent picture.

In this image (above) the photographer metered for the entire scene. The camera exposed the walls more towards the midtones, and the light comming through the window was clipped (ie: overexposed).

Hope this helps
