Handheld photography class (8) It is also excellent to use HDR to let you take pictures in the backlight.

In recent years, the technology used by mobile phones in taking photos has become more and more perfect, which not only strengthens the effect of taking photos, but also simplifies many tedious processes that were originally input into computers. One of them can be done quickly in the mobile phone, and it can also bring excellent results, that is, the function of "HDR"!

In this handheld photography class, let's introduce what functions this phone has!

HDR is actually the abbreviation of high dynamic range, which means "high dynamic" photos. As the name implies, this shooting method can bring a relatively high dynamic finished product and reduce the parts that are too bright and too dark in the photo. ''

Usually, in the past, we used a camera to take several different photos of exposure value, including those that were too bright and too dark and those of normal exposure value, and then added them to the computer software for calculation. The advantage of doing this is that you can have better calculation results, you can exaggerate like a painting, or you can simply leave out the places that are too bright and too dark.

In recent years, almost all mobile phones have this HDR function, which is very simple to open and almost a preset function.

HDR on mobile phone is slightly different from camera+computer. Whether you take a few photos or count a photo, you can get the HDR finished product immediately after pressing, which saves many steps and can almost be completed by taking a photo.

There are two sets of photos below. We can look at the opening and closing of HDR, which is a very direct result.

▲HDR shutdown, HTC U 12+ shooting.

▲HDR on, HTC U 12+ shooting.

▲HDR is off, HTC U 12+ shooting /HDR is on, and HTC U 12+ shooting.

According to the above two sets of photos, in fact, we can see that HDR on the mobile phone will not have the effect of painting exaggeration, but it can effectively reduce the bright parts, increase the details, and also brighten the dark parts, so that things that were originally invisible can be revealed.

So, why do we say that HDR allows us to take pictures in the backlight? Because the situation of backlight is usually when the contrast between bright and dark places is the greatest, HDR can get the best effect at this time.

If you want to use HDR, I also suggest that you can use it in the following shooting environments:

First, under the backlight

Used in backlight is the most direct. Visually, where the backlight is too dark, the overall brightness will increase and look better due to HDR brightness enhancement.

Second, shoot at bright places in the dark.

For example, if there is a window with slight backlight indoors, or someone happens to be in the shadow, and there are shadows and normal brightness in the picture at the same time, it can be effectively improved.

Third, the scenery along the lights

Why is the scenery along the light also suitable? This is because, generally speaking, we can get deeper blue sky along the light, but under the sunlight, there will be some shadows caused by the light. At this time, HDR can make our photos more in line with the visual effect of human eyes.

Fourth, almost all pictures are shadows.

For example, in the mountains, it is a tree-lined picture. Of course, the camera will adopt appropriate exposure, but there will still be gaps in the sky between trees. If HDR is used, not only the shadows can be brightened, but also some sky or light will not be overexposed or dead white.

HDR is a quite mature technology. When you are shooting, you can turn on the HDR option in the camera when you encounter the above four situations with relatively large contrast. The final photo should be ideal. Give it a try!

Next, I will put some HDR applications in various scenarios for your reference. You can try HDR when you actually go out in the future.
