We recently brought you an in-depth tutorial on how to use the iPhone’s built-in HDR functionality. Now we’re taking a look at an iPhone app that helps create high dynamic range images.
Pictional’s TrueHDR goes beyond the iPhone’s built-in HDR abilities. It can help you capture better images and even improve images you take on your compact camera. Pictional’s co-founders Michael Parker and Yuanzhen Li explain how the app came about.
“Everybody has had the experience of taking photos that are either over or under-exposed and don’t look anything like what your eyes saw when you took the shots.”
They realized that the iPhone’s tap-to-focus also adjusted exposure. They could then meld two images with different exposures to come up with a result that preserved details in bright and dark areas.
Parker and Li have chosen 10 images created with TrueHDR that they feel showcase the app’s capabilities. Take a look through the photo gallery to see them, along with Parker and Li’s comments, and link us to any ofyour HDR creations in the comments below.
"Almost postcard-like in its perfection, this photograph beautifully shows off the capability of TrueHDR to capture a potentially ... challenging range of light: Sunlight, mid-tones and shadows."
"We were captivated by the sense of depth, along with the range of light and contrast, from the hill in the foreground to the distant meadows. The sky and the shadows from the clouds lend nice contrast to the image, contributing to a subtle landscape painting feel."
"This photograph struck us as having an almost surreal quality. We especially like how the photographer used TrueHDR to capture the range of brightness in the scene, from the two lights on the left to the portions of the actors' faces that are in shadow."
"This photo captures the gorgeous lighting on the coast of Molokai. It has great composition and depth and was made from four iPhone photos -- two sets of over-exposed and under-exposed pairs were merged in TrueHDR into two HDR photos, which were then stitched together into a panorama."
"The photographer has used TrueHDR to beautifully capture the lights, snow, blue and purple layers of the sky and the foreground bush."
"The lighting and viewpoint of this photo give us a sense of being there — standing on a dark, cobble-stoned street ... with the soft light reflecting off the stones guiding the eye to some unknown adventure awaiting through the archway ahead. The use of TrueHDR helps the photographer capture the contrast and tonal range between the dark street and the bright archway."
"The barren, abbreviated trees create some questions and a sense of curiosity for the viewer; the trees' tops direct your attention to the details in the clouds and the green draws your eye back to the lower portion of the photograph. This is another example where the HDR aspect is essential but doesn't overwhelm, letting the viewer consider the subject material rather than the technique."
"This TrueHDR photo gives the feel of a Dutch masters painting, with a nice range of tones and contrasts."
"There is a nice sense of depth to this photo, with the sheep dotting the peninsula lending a sense of scale. The use of TrueHDR helps the photographer naturally capture the range of contrasts between sky, clouds, ocean, grassy peninsula and sheep."
"The futuristic buildings give this photograph an otherworldly feel, as if you landed on another planet. The photo captures both the sky and the materials and [the] play of light on the structures. It would have been hard to do justice to the huge range of brightness without TrueHDR. Here we also show the "before" pictures on the left — the over-exposed and under-exposed photo pair before they were merged with TrueHDR."
