I'm exaggerating a bit). I also see a lot of cheat sheets that are supposed to help you with this super hard mode, some of them are only confusing to me. Anyway I know that shooting manual is a big deal to many people. But I don't think it is necessary to do all that. You can achieve just as pretty photos on a easier way.
What is manual mode exactly? It is a setting on the more advanced camera's that allows you to set every thing exactly how you want it. Though that seems great, it has it's cons. You have freedom, but you also have to set every thing manually, and constantly adjust your settings when the light changes. If you don't your photos will be either over or under exposed. It is quite hard to master, it takes practice to get your exposure right without it taking to much time.
well is it completely useless then? I don't think that camera's would be better off without manual mode. I just don't think it's ideal for when you are taking regular photo's. It is useful when you are in a very dark situation, and your light meter isn't getting the exposure right. It is also fine when you are shooting in a studio where the light intensity (amount of light) is not changing.
when you have mastered manual mode, it is about as quick as a half automatic mode. You only are scrolling a bit more. So if you are already used to it it is not necessary to switch. But when you are learning photography I think it's a better idea to go with this method. It is easier to learn and you can achieve the same results. But it is still important that you understand what ISO, aperture and shutter speed do for your photo's.
If you don't agree with me I would like to hear why!
