I can't tell what was happening with the early threads as it looks like Shadow has removed his photos?
I've found that shooing manual really helps me understand exposure, as opposed to using the priority modes! It's one of the best ideas I've gotten on here!
Remember whilst manual forces you to control all 3 key settings within the camera, the priority modes are just as powerful. The only difference is that in those modes the camera controls one setting whilst you control the other two - the camera then sets its setting based on the meter reading and applies any exposure compensation (ie over or under exposure) to the setting it has control over. It's little different to say setting your ISO and aperture and then balancing your shutter speed off that in manual mode - save that the camera is quicker in the priority modes than you are.
In the end of course once you know how to use each mode its not a case of one being superior over the others; but about knowing which will give you the best control in the given situations you're shooting in.
