Backlighting makes people love and hate. When they are backlit, they can create dazzling outlines of light around the subject, creating a strong contrast between shadows and beautiful effects. If you hate it, you will let it be treated badly. Part of the subject's light and backlight cannot be taken into account in detail, such as the most common black face. In view of this, many mobile phone manufacturers have added HDR mode to front-facing cameras and used HDR to suppress highlights so as not to overexposure. At the same time improving the brightness of low light, the effect is indeed obvious, the only problem is that the rate is low, many times you need to take a few self-shot to get the desired effect of backlighting.
The reason for this problem is very simple, because the HDR works when the user presses the shutter, it will shoot an overexposed, a normal, an underexposed photo, and then synthesize them into a It is not difficult to see that HDR synthesis is performed after the shutter is pressed, so the user cannot preview the effect of HDR synthesis before shooting. This means that when you press the shutter, the final effect of HDR depends on the nature of the matter. .
Because of this defect in HDR, OPPO introduced 3-HDR technology for the first time on R15. Based on the previous OPPO four-pixel integration technology, it uses a different exposure between each sub-pixel to achieve hardware in one pixel of RGBG. Real-time HDR, finally achieve real-time display of the final results in the backlight self-timer, to restore the reality seen by the human eye. You can simply understand that HDR synthesis is no longer the work after pressing the shutter, but truly WYSIWYG.
With the help of the following comparison chart, it can be clearly seen whether there is a difference between the 3-HDR technology and the mobile phone without the 3-HDR technology. When the backlight is reversed, a screen is seen on the screen while a 3-HDR technology blesses R15. Clearly shows the blue sky and white clouds, which means that the ultimate HDR effect is no longer a matter of command, but can master it.
Thanks to the use of 3-HDR technology, when using the OPPO R15 backlight self-timer, you can see the final HDR effect on your mobile screen in real time. You can adjust it to your liking anytime, even if the picture below is facing the sun and other natural bright light. , It can also greatly enhance the face and background brightness in the backlight environment, but also does not appear too dark or overexposure.
In terms of zooming in, the R15 not only restores the details of the human face, but also the hair that is in contact with the foreground light. Clearly visible, this is enough to confirm the strength of OPPO R15 backlight self-timer.
Since 3-HDR technology is so good, whether other mobile phones can also enjoy the 'What You See Is What You Get' self-timer experience? It is not easy at present, because 3-HDR needs to be based on 'pixel reconstruction' technology. The 'pixel reconstruction' was introduced on top of R9, and further upgrades were made on top of R11s to achieve the intelligent aggregation of four pixels in a dark light environment into a large 2.0 μm pixel, with a three-fold improvement in light-sensing area. A new debut 3-HDR It is also an extension of this technology, which has experienced many years of technological accumulation. Therefore, for a long period of time, only OPPO mobile phones can enjoy the convenient experience brought by 3-HDR.
After watching the backlight self-timer, we take a look at the rear, R15 uses the new Sony IMX519 sensor, both f/1.7 large aperture, 1.22um single pixel area and 60 frame rate and other characteristics of the picture, into the light is more full, dynamic camera more Fast, it's the performance of the backlight shooting we still look directly at proofs.
The proofs were shot at around 9:00 in the night. Behind the characters was a bright advertising LED card. It was also one of the most frequently encountered backlighting scenes. From the perspective of the proofs taken by the R15, it has a very good tolerance. It is a backlit scene with a large contrast of light and darkness. It also achieves a clear reduction of details. The characters in the shadow are clear and the background is not exposed.
Zooming in on the details, the face in the backlit scene is still white. No matter whether it is facial features or hairlines, it is clear enough. There is no such thing as a “black face” problem. The LED billboard with the brightest proofs is not only not white because of high exposure. One piece, even with the text and the pattern on the billboard, is clearly visible. The dark part is brightened, the bright part is exposed, and the excessive balance between the dark part and the bright part is naturally balanced. This is the answer given by the R15 backlighting.
to sum up:
The OPPO R15 series comes with 20 million innovative 3-HDR technology. From the actual performance point of view, the 'what you see is what you get' backlighting experience is really stronger than the traditional HDR, but also for the mobile phone industry. Set a new benchmark for backlight self-timer. Thanks to better and smarter software imaging algorithms, R15 series can well balance the performance of dark and bright parts when shooting backlit scenes, no fear of light, want to shoot.

If you hate it, you will let it be treated badly. Part of the subject's light and backlight cannot be taken into account in detail, such as the most common black face. In view of this, many mobile phone manufacturers have added HDR mode to the front camera to suppress excessive light exposure by HDR. At the same time improving the brightness of the low light, the effect is indeed obvious, the only problem is the low rate of filming, many times you need to take a few self-shot to get the desired effect of backlighting.
The reason for this problem is very simple, because HDR works by taking an overexposed, normal, underexposed photo at the same time as the user presses the shutter, and then synthesizing them into a single image by the algorithm. It is not difficult to see that HDR synthesis is performed after the shutter is pressed, so the user cannot preview the effect of HDR synthesis before shooting. This means that when you press the shutter, the final effect of HDR depends on the nature of the matter. .
