That was a unique moment that in a march of 2024, when there was usually already no snow or ice, but not this year. Literally in one day the temperature rose at one moment and the snow field (which is just field of grass framed by small fence) began to melt and with the "standart" puddle reflections, I discovered a huge puddle almost a lake right in front of the Saint Isaac's Cathedral. Because of the slope from corners to the center, the water moves a bit, so its not the same "mirror" reflection as in small puddles, but such a size! Basic editing of light & shadow in lightroom, then I decided to change sky (from regular blue to something more interesting) in photoshop. Sony ZV-E10, F/11, 3.2sec exposure, iso100, 16mm.
