From the developer:
Sometimes the situation just doesn't allow you to take multiple exposures, don't have time to set-up the tripod, or the wind's too strong, or there's too much movement. No worries, simply take a single JPEG or RAW and let HDRtist work it's magic on your photo. This is sometimes known as simply tone mapping a photo or creating a fake HDR, or just FHDR.
Getting your exposures or photos into HDRtist , is a breeze.
