learn DSLR

assalamualaikum
aaanndd a very good day :)

well actually i am not quite sure where to begin...
there're lots of stuffs i can begin with...

well..let's start with these three things
-aperture
-ISO
and
-shutter speed
these three things are somehow related in producing a well exposed picture/image

now let's start with the aperture

WHAT IS APERTURE ?

aperture is basically the size of the opening allowing light to reach the sensor of your camera.

see this..

see what changes? (ini bukan iklan laptop hijau timekaseh :p )

well basicly that is the aperture (the thing(mechanism) inside the lens)

reading aperture is sometimes confusing especially for beginners. 

The aperture is usually indicated with the f-stop unit. as an example f/3.5 or F3.5 ..

the smaller the number = the larger the opening

and oppositely

the larger the number = the smaller the opening..

tgk ni haa...

see how it works? (i googled this)

just as i said before :

"the smaller the number = the larger the opening

and oppositely

the larger the number = the smaller the opening.."

THE FUNCTION!

well it's obvious that larger aperture (smaller f-stop) allows more light entering the camera

and smaller aperture (larger f-stop) allow less light entering the camera :)

here, see this 

that's what i meant

i shot all of them with the same setting but notice that i changed the aperture value

and it affects the brightness of the picture....

buttttt

that's not all of it!

aperture also affects the "depth of field" (i will tell you later about this)

read first

lager aperture (smaller f-stop) would produce shallower depth of field

or more bokeh

smaller aperture (larger f-stop) would produce larger depth of field

or less bokeh

here see this 

:)

see...smaller aperture gives less bokeh/blurr

in other word more depth-of-field

[ I will tell you about depth of field later. Let's just focus on this first :) ]

as a conclusion : 

larger aperture = brighter image / more bokeh

and

smaller aperture = darker image / less bokeh..

that's all for now... i'll continue later with the "shutter speed" :)

assalamualaikumm :)
