This is one of the biggest photos I ever took. Overall it is 102Mpix big, created from 8 bracket series, each one consisting of 5 exposure. I actually made a blog post about how it was created, and that can be seen here: http://blog.hdrshooter.net/2013/11/19/big-one-process/
If you would like to zoom in to see all the stunning detail, you can find a zoomable version here http://blog.hdrshooter.net/zoomable-panoramas/big-one/
This photo was taken from the top of the SNP bridge in Bratislava, early this year.
