![]() ![]() In this way, you can easily understand how your eyes will work. If we like to describe it in a specific way, then it could be the focal length of an optical system that will set the cone bundle of rays coming from the image plane. In optics, the aperture is considered a hole or an opening where the light will travel. We call them the shutter speed, ISO, and aperture.Īmong them, the aperture is the most significant for photographers. SMALL APERTURE VS BIG APERTURE PORTRAIT PROFESSIONALNo matter how creative you get, at the end of the day it all boils down to the fact that you need a certain amount of light to hit the image sensor in your camera (and your camera doesn't care how it gets there).Hello, Are you a professional photographer? Do you love to know the details of your camera settings? In photography, there are 3 pillars that we consider the most. Once you truly understand this relationship, the possibilities are endless which is why taking photographs is an art form not a science experiment. What's next? This is where the shutter speed comes into play. However, even with your aperture set at its widest setting, you still might not get a properly exposed image. For example, in low light situations, the camera should be set to the aperture that will let in the most light something like f/4. This relationship is the driving force behind all photography decisions and as such it is important to know and understand because not every type of photograph will allow you to chose from a wide variety of apertures. Remember earlier, when increasing the aperture by one stop also changed the amount of light that reached the camera sensor (assuming everything else is kept the same). As the aperture is changed in size, the amount of light that reaches the camera sensor also changes. SMALL APERTURE VS BIG APERTURE PORTRAIT ISONow for those of you that are a little more advanced, I realize that this doesn't take ISO into consideration but this is meant to explain the inverse relationship between aperture and shutter speed to the beginner crowd.Įxposure is the amount of light that gets to the image sensor. Translation: For a properly exposed image, you can either make the aperture wide and have a quick shutter speed or have a narrow aperture and have a slow shutter speed. In the end, the same amount of water will reach the bucket (the image will be exposed the same amount). You can either use a small garden house and leave it on for a long period of time (use a narrow aperture with a long shutter speed) or you can use a large fire house and leave it on for a very short time (use a wide aperture with a quick shutter speed). There are two ways to fill the bucket with water. Let's pretend you have a hose (the size of hose is related to the size of the aperture) and you are trying to fill a bucket (the bucket is the image sensor on the camera) with a certain amount of water (the water will be the light particles you are trying to capture to make an image). Now lets try the same sentence with inserts relating each story item to its designated camera item. In the end, the same amount of water will reach the bucket. ![]() You can either use a small garden house and leave it on for a long period of time or you can use a large fire house and turn it on for a very short time. Let's pretend you have a hose and you are trying to fill a bucket with a certain amount of water. Personally, I would relate aperture to a hose with water coming out. One thing that helped me when I was just starting to get used to this idea was to relate this idea to something I've used/dealt with before. If you feel confident that you understand aperture, skip this section. ![]()
