Hello! I am trying to make this nice panorama (from my visit to the Seychelles Islands), But the horizon just never seems to be good... There is cracks in it, and it is not a straight line.... At one point, there is also an issue with the water, the stones are put nicely together, but the waterline is bad. What would be the best solution for me to fix this? If somebody wants to fix it for me, it is fine, but I would prefer to learn it myself, So if you do, tell me the steps you did. I can provide a link to a full size file if you want to give it a try (.dng). (or provide all the separate images I putted together (.nef)). Thanks!
