ive been tryin to get some very cool pics using all this stuff and i dont htink i did very good cause in the manual it doesnt explain very vood whats happening, like with the shutter speed what exactly is the effect on the pic by leaving it open more time if the object doesnt move?, all ive notices is that the more open the more light shows up in the pic,
is there some page like dedicated to learn all this stuff?
this was the best pic i could get by using these things:

and this happened when i left the shutter open and i dint know this was going to happen:

and most of my pics turned out like this or worse..

but im willing ot learn i just hopw i had a better camera
