larger aperture = faster shutter speed, shallower DOF (blurred background)
smaller aperture = slower shutter speed, deeper DOF (clear background & foreground)

Not too sure what u wanted to know...

But giving it a shot..

All condition being the same.

Small aperture > Longer shutter speed
Small aperture > Deeper depth of field


Bigger aperture > Shorter shutter speed
Bigger aperture > Shallower depth of field

Thanks.

1. So "normally" night shot what Aperture settting to use?

2. Cam -> Object (sunlight at the back of object) What Aperture setting to use?

3. Cam -> object (sunlight shine onto object) what Aperture setting to use.


I know there isn't any standard setting. Just wanna get an idea on how to control the Aperture setting.

Tahnks.

If you want bigger lens opening(aka bigger aperture), you need to decrese your aperture value or F number.
If you want smaller lens opening(aka smaller sperture), you need to increase your aperture value or F number.


Bigger F number = smaller lens opening(small aperture)
Smaller F number = bigger lens opening(big aperture)

depth of field in short is the sharpness of the back ground.
It is affacted by :

1: distance between the lens and the subject
2: focusing lengh
3: aperture.



Hope this help.

for 2 might try smaller w flash... else might get a lot of CA esp if there're sharp edges..

Personal advise - In order to accelerate your understandings, you might want to consider to borrow photography books from the library.
It helps alot. Especially for me. ;)

don't confine yourself to rules in the start. There is no perfect aperture, speed or lighting to use. It only depends on what the photographer want to acheive with his tools. I recommend you to take multiple exposure with different setting to find out for yourself which one works the best for you. Since it's digital, no wastage so why worry?

With no disrespect, do go to the nearest library and borrow a book on photography. I started out that way, and everything became so much clearer.

Hmm.. might be due to the camera. Seriously I do not know what is made of modern cheap digital cameras nowadays. It's harder to spot difference sometimes. Well, my advise is for you is to use a manual SLR to experience it.

Though books are useful, you will still need onhand practice inorder to understand the fundermentals. if you are not learning anything from it, you will have to try again until you know.
