Turn it on when shooting in low light. They either create photos that are too grainy—or photos that are full of contrast. Specifically, turning on HDR will reduce grain in your low light photos. This results in higher-quality photos overall.
Additionally, HDR can help expose for streetlights. In low light photos, streetlights often become white and lose detail. However, with HDR, streetlights are properly rendered. HDR is great for dealing with high contrast situations.
In fact, great silhouette photos get rid of all detail in the subject! Look at the photo above. That way, you can capture your perfect silhouette—without having to deal with too much detail.
Unfortunately, you generally cannot use HDR to take photos of moving subjects. As I mentioned above, an HDR photo is actually a combination of several photos. But these photos cannot be taken all at once. Look at the person in the photo below. This is what happens when you use the HDR feature while photographing a moving subject! This is designed to compensate for movement during HDR photos.
No matter your iPhone model, try to avoid taking HDR photos of moving subjects. Do you want to create photos with gorgeous, saturated colors? HDR is great at bringing color back into scenes that are too light or too dark. HDR brings detail back into the scene. But what if you want to have a contrast-heavy, dramatic image? After all, sometimes you want to take a photo because you like the drama. Just remember: HDR is great for maintaining detail. But sometimes you want to lose detail—in order to create beautiful, dramatic images.
Free Video Reveals HDR stands for h igh dynamic range. Exposure refers to how light or dark your camera makes the scene. The iPhone camera simply cannot photograph both light and dark at the same time.
The HDR setting allows you to capture photos of high dynamic range scenes. What is HDR in camera? So, how exactly does the HDR iPhone camera feature work? When you use HDR, the camera captures several different exposures at different brightnesses. The camera then blends the best parts of these exposures to create a single well-lit image. As a result, the dynamic range of the photo increases. While this process might sound complex, the good news is that the iPhone does it all for you.
All you need to do is switch on HDR and take a photo. The camera will shoot and combine the three exposures to create your HDR image.
The iPhone HDR feature is great for shooting high contrast scenes with dark shadows and bright highlights. HDR is perfect for landscape photography. Landscape scenes are often high contrast, with the foreground much darker than the sky. The photo below was shot without HDR. The brighter parts of the sky are completely over-exposed. They appear pure white with no color or detail. The darker areas, such as the boat and plants in the foreground, appear slightly under-exposed.
Now compare the above image to HDR version below. Using HDR has resulted in a perfectly lit photo with plenty of color and detail in both the foreground and the sky. It can be used in other shooting situations with tricky lighting conditions. The examples below show how you can use HDR when photographing a shaded subject against a bright sky.
If the shadows appear too dark or the highlights are too bright, switch on HDR in the Camera app. Knowing when to use it, and when not to use it, is key to capturing the best quality photos in different situations. If you want to intentionally capture the high contrast nature of a scene, keep HDR switched off.
This allows you to capture sharp HDR photos of moving subjects. If you have an older iPhone, be wary of using HDR when photographing moving subjects. This is especially important when shooting HDR photos in low light. For best results, use an iPhone tripod and iPhone tripod mount.
This ensures it remains perfectly still while capturing the multiple HDR exposures. Also, ensure Keep Normal Photo is switched on. This tells your iPhone to save a non-HDR version of the photo too. If you have these options, choose On. Note that it takes slightly longer to capture an HDR photo than a regular one. This is because the camera has to capture three images at different exposures and combine them into a single photo. Any movement would result in a blurred photo caused by camera shake.
HDR is an amazing tool for helping you create better exposed photos. It has a range of HDR shooting and editing options, allowing you to customize the final result. It has vibrant colors, and lots of detail in both the shadows and the highlights. For comparison, below are two photos of the same scene that were shot with the native Camera app.
The difference between the two native camera photos is quite subtle. The HDR photo has more detail in the bright areas of the sky, and slightly more detail in the shadows. It also produces vibrant colors that could normally only be achieved with a photo editing app. The camera screen will appear as shown below. Tap the Menu icon three horizontal lines , then open Settings gear icon.
Check the options are set up as shown below, then tap Done. Drag these boxes around to select which parts of the image you want to expose for, e. When you press the shutter button, the camera needs to take three separate photos at different exposures.
To avoid any blurring in the final image, hold your iPhone steady or mount it on a tripod. The example below shows what happens if you move your iPhone while the camera is taking the pictures. When the app has captured and blended the three exposures, the resulting HDR image is displayed. The HDR effect can be overpowering to start with. The colors might look over-saturated, and the highlights may appear too dark or grainy.
You might also see a bright halo effect around the darker areas of the image. If the HDR effect is too strong, make adjustments to the image using the sliders in the editing panel. You can access more editing options by tapping the icons at the bottom of the screen.
Tap the left icon for exposure sliders, the middle icon for color sliders, and the right icon for cropping, filters , frames and text. If you use the editing tools to adjust the image, save the edited version to the Photos app by tapping the Save button floppy disk icon.
There will be three separate images taken at different exposures, followed by the HDR version which is a combination of the three photos. Then tap the Photo Library icon between the gear icon and timer icon. The Library Mode message will appear asking you to select up to three exposures. There are benefits to leaving HDR turned on on your smartphone because, as noted above, the latest phone cameras, operating systems, and chips are pretty good at figuring out when it is advantageous to shoot in HDR.
Just tap the HDR icon to turn it off. As ever with Android phones, options and settings will vary from device to device, but you should be able to manually toggle HDR on and off in your camera settings. Once you get the hang of it, HDR can be a great tool for getting better pictures. This post originally appeared on Lifehacker in March It was updated on May 5, , June 12, , and Dec.
