I bought this to compare with Pro HDR X. HDR apps have a problem with halos in areas of high contrast. Its ugly. You get what look like smudges in th sky and in other areas of flat color or tone. Based on sample pictures, I thought this app might do that less than Pro HDR X. It doesnt. It also doesnt create the range of exposure that Pro HDR X makes. True HDR uses only two exposures, versus three for Pro HDR X. Theres not as much information to work with, so the range is narrower. On the plus side, True HDR is good at aligning images, something Pro HDR X has trouble with. This is valuable in low light, when exposures are longer and the combination of exposures happens over a longer period of time. True HDR also has more natural color, which may or may not be what you want. Pro HDR X pumps the color, so you get those gorgeous images with blue blue skies and green green trees and grass. Its a little much. True HDR is good for getting a wider range of exposure than a single shot, it aligns multiple images well, and it uses more natural color. If you want a wider range, try Pro HDR X and--if you dont like candy-store color--adjust the saturation down.
