I took a picture rather similar to this five years ago. Unfortunately there was a distracting cloud that sort of ruined the photo.
Ever since then I have tried to take the picture without any distractions. Unfortunately either the weather, flowers or noctilucent clouds haven't been as I would have liked.
Last week was different. The weather was perfect as well was the noctilucent clouds. There were a few blooming flowers left, so I was able to take the following picture.
I was waist deep in the lake. The picture is made of 15 frames, focus stacked. Then I manually added some four frames on the stacked image, because there were a few blurred areas. Something you should expect when you are dealing with water. It moves, although very gently, but enough to move leaves and flowers ever so slightly. Not a problem, if the shutter speed wasn't over a second (shot at 2am)
