§ If there are parts of the image that are in shadows and others are in highlights,
use HDR mode to capture three shots of different exposures and combine them
into one shot. Keep HTC One steady or place it on a level surface when using
HDR.
§ When taking a panoramic photo, consider the whole scene and focus on an
object that has a neutral tone to help keep the exposure balanced in the
composite image.
§ If your subject is lit from the back, use Backlight scene to highlight the
foreground and keep some details of the background.
Other tips
§ In Camera settings, tap Grid to help frame the subject better or improve the
composition.
§ If taking pictures under fluorescent or incandescent bulbs and the subject
appears to be off-color, choose a white balance option in Camera settings.
Check the image on the Viewfinder and select the option that displays the
closest color to the natural color of the subject.
§ In Camera settings, you can tap Image adjustments and adjust the exposure,
contrast, and others before taking the photo.
§ After capturing the photo, you can continue to edit the contrast, brightness, and
other settings in Gallery. You can even straighten a slightly skewed photo by
tapping Edit > Tools > Straighten.
