In order to improve the final result of the photographs, practically all smartphones already offer HDR mode.
Discover 7 tips to know when and how to use it.
The dynamic range or dynamic range of the chambers is usually much smaller than the human eye. To try to improve this aspect, some techniques were created to extend this range of digital images, such as the HDR example.
In a very short way, this mode aims to obtain the greatest dynamic range possible with the camera of your smartphone, trying to improve the lights and shadows.
In order to make the most of HDR, we present some tips for using this system.
No automatic mode
The HDR's automatic mode helps everyone who does not have a great deal of photographic knowledge not need to think too hard when deciding when to use this mode or not. However, in some smartphones the automatic modes are not always well adjusted. In these cases, HDR can be used when it is not necessary which will give the photo a more unrealistic look than it should.
In general, whenever possible, it is advisable to use the HDR mode manually. For example, when taking a photo in backlight (or other types of high light contrast), in most cases it will be necessary to use this mode.
Test first without HDR
Sometimes, in order to get an excellent photograph, it is best to stop for a while to be able to experiment with different modes. Try taking a photo without HDR first. Then, you can check whether the dynamic range is suitable or not and thus decide whether it is necessary to activate this mode.
Dynamic range is the camera's ability to capture details in the lights and shadows of the same image. That is, if you take a normal photo and you notice that an area is darker or lighter for your taste, you will know that the dynamic range of the smartphone is not enough and you can use the HDR.
Don't overdo the HDR effect
There are applications like Snapseed (photo editors) that have the possibility to shade or increase the effect and intensity of the HDR.
If you put it at maximum, you will end up with a more imperfect or unreal image than you should.
Autofocus can help
Regardless of whether you use automatic HDR mode or just activate it manually, there is a little trick that can help you sometimes. As already mentioned, there are smartphones where the HDR is poorly adjusted, which can lead to a very clear or burnt photo.
The trick in this case is to touch the bottom of the screen to re-analyze the image and adjust the light exposure. It can result in most cases, for example, touching the brightest areas so that the smartphone takes this light as reference and increases the shadows with the HDR.
Always save the original photo
Some smartphone cameras allow you to take two photos at the same time, where one is presented with HDR and the other without this active mode. Usually these devices keep the original photo so that it can be analyzed at the end which one is preferred. If your smartphone has the possibility to save the original photos, it is recommended that it is always active.
In this way, whenever necessary, you can retrieve the “original” photo, that is, without HDR mode, so you can compare and decide which one you like best without having to take a new photo. This is especially useful when you don't have time to walk around taking multiple photos by turning HDR mode on and off.
Disable HDR at night
HDR and night shots hardly get along, which is why it is generally best not to use this mode at night. If you use it, it is easy for the smartphone to increase watercolors as a form of exposure. This means that the details will be lost in the objects that appear in the photographs and that the edges may be blurred or blurred, as if it were painted.
There are smartphones with good HDR quality at night, like the Google Pixel, but if you don't have a state-of-the-art device the best thing is to forget about this type of photos.
Smartphone stabilized and without moving objects
In order to form an HDR photo, your smartphone captures several photos to obtain a final result. In most cases, taking pictures with moving background objects is always difficult even during the day. In an HDR photo this difficulty turns out to be greater.
That is, in a case that you have to take a picture with moving elements it is best to forget the HDR mode. On the other hand, it will always be easier for these cases to have the smartphone as stable as possible in order to improve the final effect, not discarding the idea of using even a tripod.
Apply these tips to your photos and you will see that you can achieve better results on your smartphone.
