Agree with Pete. Working with fully manual settings is just one of your options, that's all. Sometimes it's appropriate and sometimes it isn't. If I'm outdoors there's a good chance the light is going to change without much notice. I CAN opt to shoot fully manual but it means remembering to check all your settings each and every shot. Who has time for that if the subject is also moving around in front of them? Not me, for sure. Which semi-automatic mode I choose goes back to that question I asked - what is it you want your shot to look like. If I know I want a shallow depth of field for all my shots, or I know I want full clarity front to back in all the shots, I'll choose aperture priority. I set the aperture to get the depth of field I'm looking for and let the camera deal with the rest. Or, if I know I want to blur movement, or I know I definitely want to freeze movement, I'll choose shutter/time priority and let the camera figure the rest out. If I'm getting consistently over exposed shots with these, or underexposed, I will dial in some exposure compensation - effectively say to the camera 'When your figuring this out, go for it but let in a bit more, or less light than you first calculated'. There are lots of false beliefs around photography out htere. Some believe their camera system is the best or that you should only shoot manual, or that you can't do anythign with a kit lens or that flash is always horrible light or that not using flash is a cop out and demonstrates a lack of skill. It's all tosh. Basically you can take a photograph with a biscuit tin and so long as you are getting the results you wanted it doesn't really matter how you got them. Editing is a whole other box of frogs with just as much nonsense spoken about it but can be a lot of fun!
