Unique Photography Charm Nubia Z5 Photography Sample Evaluation | Ainongji - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

Nubia is a new domestic brand. On February 1, as the first mobile phone of Nubia, the Z5 will be officially launched. When the Z5 was launched, the editor released the shooting evaluation of the Z5 engineering version. However, note that this is only an engineering version, which may be different from the launched version. Please see the detailed evaluation below.

Note one thing: Z5 does not know whether it is due to the firmware. There is no ISO adjustment option. ISO is all automatic, and ISO cannot be detected in the picture. Therefore, there is no ISO in the EXIF information in the lower right corner of the picture. In addition, there is a problem with the shutter information. All of them can only display 1/15S, which should be corrected in the official version.

Let's take a look at the Z5 shooting picture: Z5 has two photography modes, one is professional mode and the other is automatic mode. This is the professional mode in the above figure, which can process the focus and metering points separately.

This is the automatic mode shown in the above figure. In the automatic mode, the focus and metering point are at the same point as the ordinary camera, but it has an HDR function more than the professional mode.

However, in addition to controlling light metering and focusing, the professional mode also has two auxiliary lines (bisector and golden spiral). In addition, when the phone is placed horizontally, the compass can be displayed.

The spirit level can be displayed when placed vertically.

Purpose of professional mode

Next, we will learn about the advantages of the professional mode of separate processing of focus and metering points:

Xiao Bian first gave an example: when shooting the trees in the above figure, the focus and metering were at the same point, and the camera detected that the focus position was very dark, so it would increase the exposure to show the objects in the focus, but the two sides of the picture were overexposed, completely white.

At this time, we just need to drag the red metering point to the place with strong sunlight outside (green is the focus), and we can get a picture with normal exposure. There is no need to move the mobile phone and refocus. Just set the metering point at the desired place to change the exposure of a photo.

The following examples also clearly show the benefits of separate processing of focus and metering points: The focus and metering point are at the same point, and the daytime exposure of the background is too much.

Then drag the metering point to an appropriate position to correctly expose the photo.

The focus is at the same position, and the sun behind the editor completely covers the content to be shot.

By adjusting the metering point, the desired exposure effect can be obtained.

Because of this convenient function, the samples below are basically taken in professional mode.

Vision

Let's take a picture of the Z5 shooting perspective:

This is the 100% screenshot of the previous one. It can be seen that this camera performs well in the distant view, and it will not be blurred when zoomed in to 100%.

This picture was taken near dusk. It's already dark, but the overall noise is well controlled, but the details are not as clear as in the daytime.

More future proof sheets:

Macro

In terms of macro, Z5 really does a good job. It can take macro photos at a very close distance, and the color performance and background virtualization are very good. The background virtualization is soft and not stiff, and the focus is clean.

This is a 50% screenshot of the previous one.

More macro proofs:

Nightscape

The night scene is still worth affirming, but it needs some skills to easily take a good night scene.

This is a 50% screenshot of the previous one. It can be seen that the details are good after zooming in.

HDR

The HDR function of Z5 needs to be enabled in the automatic shooting mode. Why is it not available in the professional mode? The following editor will also tell you.

After HDR mode is turned on, Z5 will take two photos, one with HDR turned off and the other with HDR turned on, so it will take a long time to generate. So make sure that the mobile phone is stable enough during the shooting, or the picture will be destroyed.

This one was shot with HDR off. The dark part of the picture is pure and there is no noise.

This one is after HDR is opened, and the originally dark places are supplemented.

Here, I will explain why there is no HDR in professional mode: originally, HDR was used to expose photos correctly. In professional mode, because the metering point can be adjusted by itself, in fact, you can control the exposure by yourself.

This is the screenshot of the light metering point adjusted by the minor editor in professional mode.

This is an image in professional mode. You can see that by adjusting the light measuring point, you can basically achieve the image effect that can be taken only when HDR function is turned on.

Comparison of more HDR and self adjustable photometry samples:

This photo was taken by adjusting the metering in the professional mode. It can be seen that in the case of strong light source, the details of the ball lamp in the sample shot by turning on HDR are better, while by adjusting the ball lamp at the metering point, the details of the ball lamp will be lost.

Let's take a look at the screenshot:

On the left is the sample of HDR. The right is the sample sheet of self-adjusting metering.

There is a leaf in the ball lamp. HDR proofs can be clearly displayed, while self adjusting metering proofs will sacrifice the details of the ball lamp because of the overall picture.

From the above sample comparison, we can draw a conclusion: in the case of non high light source direct light, it is not necessary to turn on HDR, and you can shoot good samples by adjusting the metering point in professional mode. Under the direct light of high light source, HDR needs to be turned on to supplement the picture details. When you shoot with Z5 in the future, you just need to pay attention to the use situation.

Photography summary

Advantages: High pixel, which makes the ability to represent the distant view not bad. Moreover, it can adjust the focus and metering point by itself, which is flexible and convenient for shooting. HDR performance is good, and the ability of night scene to control noise is also good.

Disadvantages: ISO cannot be adjusted, which is a great pity for the small editor (you can go to About the phone ISO, aperture and shutter Popularize science). The imaging speed is very slow, which is a big problem for some people with unstable hands.

The above is some of the Z5 shooting samples and comments, but the Z5 on the small editor is only an engineering machine, and in terms of photography, the effect may be slightly different from the official version. If you have any questions or suggestions about the article, you are welcome to comment on it below, and the editor will reply one by one.
