images are absolutely fantastic. Technical question. are you using focus stacking at all, or just very small apertures (I see you are shooting f13 to f22)

Kevin - thanks very much.
Yes - I did focus stack on this trip - when needed. For example, the 1st shot is a focus stack. I used f22 at the closest focus point on the lens, then switched to a smaller f-stop (shooting 1 before adjusting focus) - then shot focus intervals (at the smaller f-stop) out to infinity. The closest ice crystals were just a few inches in front of the lens - and my thought was to use f22 at that point in order to get as much as possible in focus (even with possible diffraction). I then shot a "normal" focus stack at the smaller f-stop in order to capture as much sharpness as possible. I then let photoshop work its magic with the f22 shot - along with the other images to get as much in focus as I could. I then checked the output for any weirdness (didn't see any). May be a bit convoluted - but it worked for me.

Todd, thanks very much for the technical detail. Love the images, and learning something is always a plus. Have not been successful with focus stacking as it appears, at least with one of my lenses to change the size of the image slightly, and have some difficulty matching stuff. Is there a reason you shot the closest focus at f22? b/c DOF is most limited when you focus close?

Fabulous work here, Todd. Too many nice images to take in at one view (I always prefer a single image to view leisurely, but that's just me). Real eye candy.

I hear you on the matching things up - there are times I have to manually blend the images...
As for why f22 - it was primarily a "just in case" image. With the lens focused as close as it would go - I took my first shot at f22 - just in case it provided any additional dof. I then adjusted my f-stop to a "sweeter" spot on the lens (and before adjusting the focus) began a "normal" focus stacking exercise. Not sure how much it helped - but it was all I could think of while I was laying on my chest, feet above my head and my face just off the surface - oh, and it was around 0 degrees F that morning (although I couldn't really tell).

Thanks everyone for the kind comments - greatly appreciate it!

That is an awesome set Todd. Some fantastic images there. Loved the way you composed these shots.
It sucks that you had to cut short your trip. I love areas where there is no cell phone coverage.

Wow. If this is what you did in 3.5 days, I wonder what you would have come back with in 7! I think the first one is especially outstanding.
I agree - no cell coverage is best - but in this case I wasn't able to monitor stuff I needed too. No problems - I'll just go back!
Actually - another 3.5 days may not have helped much. Dave stayed for the balance of the trip - and he was faced with poor conditions each of the days. Guess he's going back too...
