Aperture, shutter and ISO value
With this camera simulator you can try different aperture and shutters to affect photography’s light, depth and motion blur. Try also to change the camera’s light sensitivity by manipulating its ISO value. A higher ISO value gives higher sensitivity to light, which allows faster shutter speeds. The disadvantage is that the picture is more grainy.

Aperture
The Aperture function is to regulate the amount of light admitted through the lens. The larger the aperture opening, the more light comes through.
How the aperture is set also affects the image depth. If the aperture is large (low aperture value) the light transmission will be height and the depth of focus short. Which means that when the aperture is small (high aperture value) the light transmission will be small and the depth of focus far.
To see how this looks, you can click in the box “link aperture/shutter” and pull the aperture control. Note how the background depth of focus change.
Shutter
The camera’s shutter regulates image exposure. The longer the shutter is open, the more light get through. When shooting, it is important to find the right balance between the shutter and aperture value.
A short shutter mostly requires a lower aperture value. The shutter also affects the image motion blur if you shoot a subject on the move. A long shutter time results in a motion blur while a short time becomes sharper as the subject will not have time to move as much.
ISO
ISO is short for International Organization for Standardization and tells the camera’s light sensitivity. In analogue cameras with film is the film’s luminous display.
A high ISO value makes the camera more light sensitive so you can shoot with quick/short shutter speeds in a dark environment. The disadvantage of a high ISO value is that the picture is more grainy.
Light meter
Most SLR cameras has a built-in light meter. The light meter shows how the image exposure values are set.
Wow, I have just discovered this via a forum post of talkphotograhy.co.uk and what an amazing tool. I am a beginner in amateur photography, a hobbiest you could say, and this tool has just help me understand a lot of the information I have been reading on the the subject but actually allowing a quick and easy what to show the impacts of changing various camera settings.
Great job, thanks.
This is a great resource for new photographers on my yearbook staff.
Very cool. I am having the hardest time getting these values straight in my head and how they intersect to make a decent exposure — and this is helpful. This should be an iphone app.
This would be much more useful if the aperture went wider than f/4 and if you could vary the point of focus to see the effect of DoF at different distances.
Sooooo coooool.
That’s what i’m talking about.
Oh man, i’m into it right now.

which is the best camara?
great !!!! thanks a lot
This is an exceptional tool. Thank you for providing it!
A amazing and incredibly useful tool. This answers a lot of questions. Thank you
I use my iPhone and this automatically takes care of all these features for me and I think my pictures look cool. So I don’t have to worry about all of this stuff anyway.
Thank you,
Your friend,

This is shweeT!
Well very interesting. Could you put better picture please very important lala.
great web page
Well done. Except: when linking aperture and shutter it is possible to over/under expose by using shutter speed slider. The effects of such should be shown, but aren’t.
I hear and I forget. I see and I remember. I do and I understand.
Thank you very much
This is an excellent tool for teaching how the three work together and what happens when you change any one of them.
Some people need to be spoon fed apparently by some of the previous remarks. I will be recommending this to all new photographers.
