What is aperture and how it affects the quality of your photos?

Certainly, many of you use your smartphone as a main camera. Even those who have a cool or not very many, will not argue with how convenient having a good camera, fits in your pocket. In fact, now the quality of the camera of any flagship smartphone will be more than enough for shooting most everyday moments. To maintain interest in their products, manufacturers are constantly trying to bring in already and so knows well how to photograph camera of the smartphone is something new. In addition to the trend to increase the number of cameras in devices, the last several generations of smartphones also boast an increasingly wide aperture. But what is this aperture?

In our time no longer be called rare smartphones with an aperture of ƒ/1.8 or higher, although in the past it was a great achievement even for lenses professional level. Devices such as the iPhone XS Max, Pixel 3 XL and Huawei Mate 20 Pro, have aperture of ƒ/1.8. However, some producers show us a completely different level. Samsung Galaxy S10 and LG V40 value of the aperture is ƒ/1,5.

These figures, of course, important, but whether or not this aperture value makes the picture better? That’s the question we try to answer in this material.

What is aperture? It’s all about the amount of light

Generally speaking, the picture is only received and processed in a certain way light. Therefore, a good parameter to determine the quality of a particular camera is determining its ability to process light. Quality sensor paired with a great lens are a popular combination for SLR cameras, and the same applies to smartphones, though with some limitations.

The compact size of the smartphone means that the lenses and sensors it is smaller, so less light will get to them, and this directly affects the final quality of the photos. We’ve seen smartphone manufacturers use large pixel sizes of the sensor from 1.2 to 1.55 µm to deal with this limitation, getting excellent results, but the other is strictly of the coin is the amount of light that can penetrate through the lens to reach these pixels. Here, again, comes into play aperture.

What is “ƒ” (the lens aperture)

So, what is aperture? Aperture is determined by the size of the opening through which light can enter the camera. Aperture is measured in so-called “ƒ” which represent the ratio of the diameter of the entrance pupil of the lens to its back focal length. Thus, the smaller the aperture, the wider the hole and therefore more light can reach the sensor, resulting in less amount of noise in the photo.

A smaller aperture size also has the advantage when it comes to reduce the exposure time required to capture a desired amount of light, which reduces blur when shooting in motion or trembling in the hands. In combination with a good stabilization smaller aperture is able to give the photographer a clear shot even in the best conditions.

Speaking of camera lenses, photographers are often associated a wider aperture with a shallower depth of field that allows you to get the blurred background effect called bokeh. However, the smartphone camera with an aperture of ƒ/2.2 actually provides only depth of field, equivalent aperture ƒ/13 or ƒ/14 on a full-frame camera, resulting in a small blur, so modern smartphones that boast excellent bokeh, in fact, achieve this effect using software.

Although a wide aperture is not a guarantee of high quality camera, a smaller aperture provides ingress to the sensor more light, reducing the shutter speed and reduces blurriness and the amount of noise in the photo. This value should always be considered in combination with the pixel size, as bigger pixels does not necessarily require a wider aperture to capture enough light. However, smaller pixels and a small aperture – a sure sign that in low light problems will arise.

The quality of the lens

Equally important, but often overlooked, component of smartphone cameras is the lens, and, like everything else, they also vary considerably in quality. In the end, a dirty lens makes bad shots, and from this it follows that glass lens with poor clarity or transparency will reduce the amount of light reaching the sensor, and hence will reduce image quality.

Smartphones with wide aperture, such as the new Galaxy S10, require special attention to the design of the lens to avoid distortion and glare on the lens, which is a common problem on mobile devices. The distortion or the distortion aberration represents a number of problems arising from the deflection of a light beam on the direction in which he would have to go in a perfect optical system. Smartphones with a wider aperture by definition, less focused on specific portions of a scene than a smartphone with a more closed aperture, and thus more susceptible to problems.

Aberration distortion has a lot of effects. These include spherical aberration (spherical aberration) (reduced clarity and sharpness), coma (coma) (blur or distortion), curvature of field (field curvature) (loss of focus at the edges), distortion (distortion) (convexity or concavity of the image) and chromatic aberration (chromatic aberration) (out-of-focus color and split white light) and others.

One of the most important parameters is the quality of the lens, and it is difficult to judge by specifications, as many phone manufacturers don’t even mention it. This factor complicates the conversations about f-stop and pixel size, since the reduction lens can make all of these settings. Fortunately, the smartphone market now there are several well-known manufacturers of optics, among which the Zeiss and Leica.

We summarize all of the above

Now you know what aperture. But as you have probably understood, the aperture is not all that makes the camera quality. When choosing a smartphone, focusing on their fotosmoralo to focus on one only aperture value will be incorrect, since in isolation from other parameters, this number is almost useless. However, the smaller the aperture value gives a number of advantages, including the ability to make a quality picture in low light conditions.

  1. Hey, how’s it going?

    I want to pass along some very important news that everyone needs to hear!

    In December of 2017, Donald Trump made history by recognizing Jerusalem as the captial of Israel Why is this big news? Because by this the Jewish people of Israel are now able to press forward in bringing about the Third Temple prophesied in the Bible

    The Jewish people deny Jesus as their Messiah and have stated that their Messiah has been identified and is waiting to be revealed They say this man will rule the world under a one world igion called spiritualism

    They even printed a coin to raise money for the Temple with Donald Trumps face on the front and with king Cyrus'(who built the second Temple) behind him On the back of the coin is an image of the third Temple

    The Bible says this false Messiah who seats himself in the Third Temple will be thee antichrist that will bring about the Great Tribulation, though the Jewish people believe he will bring about world peace It will be a false peace for a period of time You can watch interviews of Jewish Rabbi’s in Israel speaking of these things They have their plans set in place It is only years away!

    More importantly, the power that runs the world wants to put a RFID microchip in our body making us total slaves to them This chip matches perfectly with the Mark of the Beast in the Bible, more specifically Revelation 13:16-18:

    He causes all, both small and great, rich and poor, free and slave, to receive a mark on their right hand or on their foreheads, and that no one may buy or sell except one who has the mark or the name of the beast, or the number of his name

    Here is wisdom Let him who has understanding calculate the number of the beast, for it is the number of a man: His number is 666

    Referring to the last days, this could only be speaking of a cashless society, which we have yet to see, but are heading towards Otherwise, we could still buy or sell without the mark amongst others if physical money was still currency RFID microchip implant technology will be the future of a one world cashless society containing digital currency It will be implanted in the right-hand or the forehead, and we cannot buy or sell without it! We must grow strong in Jesus AT ALL COSTS, DO NOT TAKE IT!

    Then a third angel followed them, saying with a loud voice, “If anyone worships the beast and his image, and receives his mark on his forehead or on his hand, he himself shall also drink of the wine of the wrath of God, which is poured out full strength into the cup of His indignation He shall be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb And the smoke of their torment ascends forever and ever; and they have no rest day or night, who worship the beast and his image, and whoever receives the mark of his name ” (Revelation 14:9-11)

    People have been saying the end is coming for many years, but we need two key things One, the Third Temple, and two, the technology for a cashless society to fulfill the prophecy of the Mark of the Beast
