HDR involves taking three separate pictures in quick succession, each with a different exposure to capture as much of the scene's highlight and shadow detail as possible. The camera's software then superimposes the three exposures to create a single picture containing more detail than would be possible with a single exposure. In this example, the left image was taken without HDR and the right image with (click the photo to see it full-size). Notice how the brickwork in the church is far more detailed in the HDR image, while the sky remains a rich blue without being blown out.
Pro Tip: Using HDR in action scenes can result in 'ghosting' when the shots are combined, as the three images don't quite match up, Hand wobbles while holding the camera is another cause of this, so choosing scenes where there is less movement -- for example, a landscape -- speck presidio grip iphone x tough case - black / white is likely to result in more successful HDR shots, Alternatively, an app such as HDR Camera+ from Almalence (£1.22, or a free trial) offers advanced HDR shooting capabilities, including a feature which compensates for handshakes and moving images..
Fill flash vs HDRWhen the HTC One X's flash is enabled it attempts to estimate the distance of the subject from the camera and automatically select the best strength for the flash and, generally speaking, it works very well. Typically flash is used in low-light and indoors, but it can also be used outdoors and on sunny days to provide 'fill flash', supplementing ambient lighting and helping foreground subjects pop out against brighter backgrounds. In practice, I found the HTC One X's flash struggled with this technique (middle image), perhaps gauging the exposure incorrectly to produce a weak flash. Unfortunately, there's no manual control of the flash strength.
However, taking a shot with the HDR scene mode selected (right image above) produced the better exposure speck presidio grip iphone x tough case - black / white for the foreground subject, although as highlighted above, this may not be so effective for fast-moving subjects, Group portraitAnother morsel of added value from HTC is the group portrait mode, Upon pressing the shutter icon, the camera once again takes several exposures and, using HTC ImageSense's smile detection, chooses either the best shot or -- here's the clever bit -- the best bits of each of the shots to create a single composite image with each of the subjects' eyes open and mouths a-smiling..
In-camera effectsAs well as the image adjustment settings from the camera's settings menu, various creative effects can be also applied and viewed in real-time from the effects menu. Tap the circular icon by the side of the shutter to reveal 16 looks, ranging from vignette and dots to greyscale and sepia. Many of the effects have an adjustment slider on the opposite side of the screen. These effects are fun to play with, offering a limited degree of customisation, and may shave time off your post-processing.
