Aperture limits the amount of light by adjusting how large the lens hole is open, while the shutter speed limits the amount of light that hits the camera sensor by how fast the camera’s shutter opens and closes. Aperture can be interpreted simply as a lens opening that functions as a measure that shows how large the hole is located in the open lens.
The minimum and maximum aperture values are different for all lens types. The value varies from f / 3.5-5.6. for kit lens or camera default lens.
Aperture and shutter speed have inverse values. For example, if the shutter speed is 1 / 100s it means that the shutter speed opens and closes as fast as 1/100 of a second, then the Aperture value is the opposite.
Because the aperture value is indicated by the number F or f / number. So if the lens opening or aperture is large, the f value displayed on the small camera screen.
As explained above, if aperture or aperture is large then more light enters and hits the camera sensor, so the resulting photo is brighter. Conversely, if the aperture is small then there is less light coming in and on the sensor, so the naming for the small aperture value is indicated by a large number f.
Rather than you more confused about this reverse naming, just understand that with large openings, our photos will be brighter and vice versa.
Benefits of Aperture :
1. The camera can process images as fast as we press the shot button, but images cannot be processed that fast. Depending on the Exposure and shutter speed as explained in the previous post. So the sensor on the camera takes time to absorb light to produce photographs.
2. When we use large openings, and more incoming light then to compensate we can use a faster shutter speed, therefore, lenses that have large openings such as f / 1.8 or f / 2.8, often referred to as lenses fast.
3. Because of its ability to use a shutter speed that is faster than lenses with smaller openings. Usually when looking at such photos, the first interesting thing is the blur on the photo. Blur in the background photo is often also called a bokeh, now one of the advantages of using a lens with a large opening is the cool bokeh.
4. The bokeh or blur technique in the photo background is often applied when we are photographing models or people, because the results of these photos will usually be more dramatic. there are even photographers whose photos almost always rely on bokeh. This bokeh is closely related to the discussion of depth of field or sharp space.
DoF (Depth of field) shows how much sharp space or area in the photo we take that looks sharp
If the Depth of Field or abbreviated as DoF has a large sharp space, or it can be said that most of the areas we photograph appear to be focused in the frame, then it is said to be wide or wide DoF, otherwise if the DoF is narrow then the area that appears to focus is only small, or limited to just one point where we put the focal point when shooting.
Wide or wide DoF where sharp space is visible in almost the whole photo, we can get by using a small aperture or aperture, which is indicated by a large f value.
So if you want the entire area you take in the photo to look sharp, use a large F value, otherwise if you want a narrow bokeh or DoF, and only the area you want to focus on looks sharp, use the aperture or aperture as large as possible that is owned by your lens, then areas other than those that are focused will blur.
So, from now on it’s better to check what the aperture size on your camera is rather than the megapixel size. The reason is, megapixels only affect the print quality not the quality of the photo capture.
Thank you for reading understanding aperture when shooting and the impact in your photos. And follow our photography tutorial and enjoy the steps of your photo.
