…:what we do at APictureLife in a nutshell:…


hey ya’ll!

did i leave you on manual mode without tell you what to do after ISO?… forgive me.

let me help you out with the next step.


your aperture or “F-stop” is what controls your depth of field and the amount of light that enters your camera.

think of your aperture like the pupil of your eye.

when it is bright outside your pupil is smaller, right? and when it’s darker the opposite, correct?


before light can reach your digital card it must go through the APERTURE.

you may have noticed the aperture before without realizing it. it will look like this: 2.8, 4.5, 5.6, etc- these are known as your F-stops.

the image below shows you that the camera’s shutter speed is: 1/8000 and the aperture is at f5.6

the lower these f-stop numbers are, the wider your camera opening which means… more light!


it will also mean that your focus is “tighter” with your background having a blur effect.

every f-stop number represents a 1 stop.

so if you go from f5.6 to f2.8- how many stops brighter is your picture?

2 stops brighter.

if you go from f2.8 to f5.6 you are now 2 stops darker.

does that make sense?

go outside and try it out. it will make a lot more sense once you play around with the aperture a bit (and your ISO).

you’ll also start to see your depth of field come into play.

the lower your f stop the less that is in focus.

your lens controls how “low” you can set your f stop to.

i have a lens that can go all the way down to f1.2. your lens may only go to 3.5.

depending on what you are photographing it may not be that important to you to have a lens that goes as low as 1.2 or 2.8

when i photograph weddings i like to photograph the bride’s eye lashes and flowers at a low f-stop in order to make the focus more about her.


when i photograph the family photos at weddings i always have my f-stop at least at 5.6.

i don’t want the focus to “fall off” as the number of people in the photo gets bigger.

a nice rule that i like to use when photographing groups is: my f-stop needs to be at least at the number of people in my photo.

for instance: if i am photographing 5 people, my f-stop needs to be at least at 5.6 in order to have everyone in focus. if there are 6-8 people, i will want my f-stop to be at least at an f8 or f11.

is that helpful?

i hope so.

i found this article on your Shutter/Aperture to be very helpful for me —>see if you like it here
