Vertical panoramas are tricky. You need a narrow area of interest, something that will fit in the short dimension of the final composition. Perhaps more importantly, you need enough “stuff” to fill all that vertical space, and preferably stuff that is meaningful and worth the pixels. In this case, the image came about from my desire to show the sunrise and shadow on the far hill, but also to include the still-frozen lake and sky above.
The trick was getting the naked ice near the shore, to provide some contrast to the snow-covered portion. And also to include the interesting cloud formation that came into the right position. I shot it handheld, as usual, in manual mode with the E-M5 + Leica 25mm at 1/40, ISO 250, f/8. The composite was assembled in Photoshop CS5, with only a little post-processing needed.
I like it; it captures the mood of the morning very well.
