Re: HDR Photography
ok it is like you have take 3 shots.
the first shot is suppose to be normal exposure. (i mean you set the aperture and shutter speed at normal)
…dont forget smaller the aperture is the clear the picture gonna be (small apertures are 16, 22), and larger the aperture is (which is 4, 5.6) the less the depth of field is going to be (as one thing will be focused, and rest gonna b all blurred)
-now second and third shots are gonna be done with same aperture, but** only** thing that is going to be changed is it shutter speed. so now you gonna go one stop up, and one stop down. this is called bracketing. you can also go two stop up, and two stops down.
so it is like…your normal exposure (first shot) is giving you A (aperture)= 11 and Shutter speed (SS)= 125.
so when you do the bracketing A n SS gonna be:
second shot: A=11, SS = 60
third shot: A= 11, SS = 250
and then you can combine them in fotoshap 
ps. the smaller your ISO is, the more crispier and detailed your pictures are gonna be (set it around 100)…but you have to use Tripod for that. amazingly my 100 ASA random pictures turned out good, of course without using any tripod
ps2. here you go chachi with fotografy tutorial.
