Finally, I was able to merge images that I made being at Sagres. The trouble was in that I didn’t know how to merge many HDR images in a single panorama. Now I know how to do that.
My process was as following: I made HDR images from the bunches of images produced especially for this (3 images with different exposition) and then merged them together using Photoshop’s Photomerge function. So, I got 10 HDR images that had to be merged. Every of them had size of 58MB! So, resulting image had size of 2.7GB!
But now you can see the sunset photo..
