Patrick Kizny shot this HDR sequence inside an 18th century chapel in Poland. Whether you like HDR or not, you have to appreciate the amount of work that went into this production – particularly, how smooth the slider shots were for the timelapse sequences.
He used a number of different cameras, but primarily relied on the 5D Mark II for the timelapse shots due to its high resolution. If you are interested in more about how he made it, check out the behind the scenes video below.
A detailed description of the post-production timelapse HDR workflow can be found on the Looky Creative blog.
