Mobile phones are so good at taking pictures, why do we still need SLR cameras?

One is image quality. Image quality is determined by pixel density, the sensor area of the mobile phone is so small (smaller than a small fingernail), under the same pixel conditions can not be compared with the SLR (the SLR includes the same specification of the mirrorless) (24 * 36 16 * 24), the so-called low child is a big level to crush people. This is especially true in high sensitivity conditions, and the image quality is simply worlds apart.

The second is the effect of depth of field. Due to the small area of the mobile phone sensor (base), its focal length (actual focal length) is particularly small (usually 6mm), so it is difficult to shoot depth-of-field effects (foreground solid, background blur, etc.). Due to the large foundation of the SLR, the actual focal length is the actual focal length, which can shoot the depth of field effect, even a dreamlike effect, and the effects are diverse.

Third, the group of SLR lenses is abundant. SLRs can use a lens group of around 10-800mm (Canon, Nikon), and the lens cannot be changed on mobile phones. Fourth, the accessories are different.

In terms of flash alone, a DSLR can create many artistic light effects by off-camera. Mobile phones don't. Fifth, the starting speed of the machine.

The SLR starts to boot very quickly, and you can shoot when you raise your hand. It takes a few seconds for the phone to start up.

In short, SLR is born for photography, and mobile phones are born for communication (photography is just recording), and the two go in different directions. SLR communication is very simple, add a communication module, and the Android system is OK. If the mobile phone wants to increase the sensor area, then it is troublesome.

And then comes the lens, just look at Sony's mirrorless shots. It's full-frame (24*36), which lens is not small, and the large aperture head is even larger than a DSLR! The two have different development directions, which can coexist and learn from each other.

However, for the time being, there is no question of substitution.

The topic is wrong, mobile phone photography is not good at all. The phone's photographic capabilities are basically equivalent to a 28mm-equivalent point-and-shoot camera, and the results are only roughly improvised. There is still a 108,000-mile gap between this thing and a DSLR.

Mobile phone photography is just for people who don't know how to take pictures for daily fun. Mobile phones have expanded the crowd of photographers, but they have not shaken the crowd that used to play SLRs at all. And it may cultivate potential customers for SLR.

Because in terms of focus, lens, image quality (including color depth, tolerance, high sensitivity performance, etc.), accessories (flash, optical filters, etc.), these aspects of SLR completely blow up the phone.

Taking pictures on mobile phones, generally speaking, is only enjoyed on mobile phones, or circulated through communication, it is only a kind of documentary image recording. The camera is different, due to the leap in the function of the camera's photosensitive original and lens, its response speed, quality and adaptability under special light are very different from mobile phones.

The reason is simple, because SLRs are more .........

There is a difference between taking photos with a mobile phone and taking photos with a DSLR. SLR has absolute advantages over mobile phones in terms of image quality, color resolution, and tolerance, especially in low-light scenes, SLR can rely on the advantages of larger sensors to get more light and present more beautiful image quality.

First of all, there is a difference in imaging clarity.

The CCD and CMOS sensors of camera phones are relatively small, generally less than 1 inch, while the area of the sensor of full-frame SLR cameras is generally much larger than that of camera phones, and medium-format SLR cameras are even more different.

When shooting macro scenes, the camera phone is a digital zoom with interpolation, unlike the large size of the SLR camera lens can be physically optically zoomed, and the image quality is much worse when the mobile phone shoots. If the use is just to post a moment, there is no problem, but in the computer or for commercial use such as zooming in for advertising, it may be disappointing due to blurry images.

Secondly, there is a gap in color reproduction.

Some of today's camera phones have obtained Leica and Zeiss certifications, and the imaging quality can reach a high level when shooting under conventional conditions. However, compared with the lens lens of thousands of yuan and tens of thousands of yuan, there is still a big gap, especially when shooting under cloudy or dim conditions, it is easy to cast color when shooting with mobile phones.

SLR and mirrorless cameras are large in size, and many complex calculation systems for color temperature detection are incorporated into the machine, which have a relatively accurate judgment on the spectrum of the subject, and the best shot is closer to its true color. For example, when shooting in complex environments such as abnormal sunlight conditions, the colors are easy to whiten and gray, which in turn affects the film.

Third, there is a gap in environmental adaptability.

The portability of the mobile phone is very prominent, you can shoot it when you go, you can shoot it in normal daylight or in a relatively bright environment, the imaging quality is still relatively satisfactory, and the objects with bright colors may be very beautiful.

However, under the condition that the light is too strong and too weak, due to the limitation of the mobile phone by the sensitivity and manual control, if you want to shoot silk flowing water, starry sky, night scenes with weak lights, etc., either the imaging noise is relatively large, or the image is overexposed without much image detail.

The main differences between mobile phone photography and SLR photography are:

1. SLR is superior to mobile phones in terms of tolerance, image quality and photo details;

2. The aperture of the SLR lens is adjustable, while the mobile phone is a fixed focal head;

3. SLR with large aperture lens or telephoto lens often has a good background bokeh effect, and the mobile phone has almost no bokeh effect because the focal length is too short;

4. The imaging quality of mobile phone lens is worse than that of SLR.
