HDR High Dynamic Range

Although you could get away without a tripod by shooting hand-held in brackets and let HDR software automatically align the images, I still recommend shooting with a tripod to get the best results. Aligning images works most of the time, but you would lose a portion of the image.

You can create HDR images from a single image, as long as both the brightest and the darkest parts of the image are somewhat recoverable. What this means, is that your brightest part of the image should not be completely blown out, while the darkest part of the image should not be pitch black. Therefore, you can only use images that are properly exposed with as many details preserved as possible. Keep in mind that RAW images (especially 14-bit+ RAW images) contain lots of data that you are not going to see when the image is viewed from Photoshop or Lightroom. In order to see this data, you would need to increase and decrease the exposure within Photoshop/Lightroom.

Moreover, you can also create HDR images with ability of your smart phones, for more information please visit this site:
