there were few nice fotos but its not wat i expected from a dslr camera..mebbe i dint do the settings right?
most of the pictures r quite dark n dint really stands out...seems that i must use the flash to get good pics..most of the pics are taken at iso400
I am not a pro, but picture dark, may not mean need flash. You need flash if you got the correct exposure for the photo, but your shutter speed end up being too slow (i.e. a lot of blur from movements). Blur also can mean different things - movement, or out of focus. Like some have said, some of your pix looks OOF.
For me, it's easiest to start off with Auto photos first. This lets you learn how your camera decides to read a particular situation and change it's setting to see what it thinks you want it to do. Learn from reading EXIF information such as ISO, shutter speed, aperture (f-stop).
Once you know your camera a bit more, then you will know that your camera cannot read your mind. For me, the easiest now is to move to A (Aperture Priority) mode. This lets you set the aperture while the camera decides for you the other settings. Some people prefer P mode (which I totally skipped). After that, maybe move on to S mode and finally M mode, where you are in control of ISO, shutter speed and aperture.
You can also use EV to + and make your pictures brighter. There are a lot of things to read out there if you are interested (library has books also if you don't want to buy) or you can read from the internet. After reading, must try it out on the camera itself. The more you shoot, the better you will know your cam and the better you can control the pictures coming out of your cam.
Once you have control of your camera, you can forget the technicalities (they become a part of you... automatic) and then you can focus on composing a good picture without thinking the unnecessary.
That was how I learnt how to take pictures.. one step at a time. Along the way, I learnt how to use Photoshop, then Silkypix, then Lightroom. How to eat an elephant? One bite at a time
Other people may have different route to how they learnt to take photos.
