A Winter Field Trip (Halifax, NS)

 As seems to be the trend in these times, this winter has been unusually warm, so it was mid-February before I had any opportunity to photograph water and ice (taking advantage of a Photo 101 field trip as an excuse to get out.

As I've been working with ice and water for years now, returning to it felt much like pulling on an old glove - within minutes I was back into the pleasure of working with such a magical subject, and for more than an hour (after the field trip students headed off), I explored the potential of the small waterfall.

The real gift of the session, however, came as I was waking back to the car - I passed a beach, and saw that the tide cycle had created lines of thin ice piles, which were catching the reflection of the afternoon sun off of a nearby building - which was quite interesting, visually. I set up my tripod, and discovered it was only with my longest lens (a 300mm f/4) that I could get the composition I thought...but with such a long lens, the depth of field needed to record the entire scene was essentially impossible. So, with great excitement, I turned to technology for a solution, using the Canon EOS R5's "focus bracketing" to create images to focus-stack together on the computer. After some experimentation, it turned out that between 35 and 40 frames were needed for each composition, and the below image was created.
