Need for Extra-Wide Angle Lenses in the Age of Panoramas

I like that better, and still do panos from there, but less often.
In my (limited) experience it seems software has the most trouble with combinations of foreground and background objects. If no foreground objects (e.g., trees) are present, things go more smoothly. The following are stitched photos (at least 6 frames each) from Glacier NP using a Nikon D600 (~55 mm focal length on a 24-85 mm zoom) held in portrait and landscape shooting positions, respectively. It was amazing to see how the boundary warp control brought the individual frames into alignment.

That is quite correct. The problem comes from trying to get close foreground (which often has some distortion) to match up well while at the same time keeping distant lines smooth. Sometimes the software just cannot do it without some sort of problem in the final image.

Shot of Castleton tower (left) and the Rectory, near Moab, UT. I was hiking near the Fisher towers and used a legacy 200 telephoto lens, 1/125s, ISO 64, F5.6. It's a bit softer than my liking from the tele, but sharp enough.

As a sidenote, about a decade ago a few friends and I climbed castleton tower, one of the fifty classic climbs in North America. What a view from the top that was! If I can find one of my old prints from that day, I'll post it.

I don't know. It still works for me. Try going to the Home page (Light Stalking: Photography Blog and Community). The article is on Page 3, January 27, 2017.

Are you using a dedicated panning head?

A while back someone was asking about alternatives to Photoshop, especially free or low cost ones.

I stumbled across this site yesterday so thought to post the link here. It's an article exploring those alternatives.

A guide to Adobe's Photoshop lineup and the best alternatives
I use Elements. I have found it to be very capable and generally available around $60-70.

No, these were hand-held shots. My only tripod has a ball head, which doesn't lend itself to steady horizontal panning.

Wow! Great catch.

I need to get a new circular polarizer. The candidates are Breakthrough Photography X4 CPL that they claim is the best available @ $149. The next contender would be B+W XS-Pro HTC at $95.50, or Hoya Pro1 at $61. Which one is the right choice? I am willing to pay more for a better resulting image.

Interesting, never heard of the Breakthrough.

I ordered the B+W just the other day. It's suppose to be thinner, to minimize the chances at vignetting.

However, I've heard some claims that it's too thin that you can't put a regular lens cap on it.

I've also used the Marumi polarizers too. They're between the price of the B+W and the Hoyas. Nikon has one for about $150 too.

Also I've seen Zeiss one for $180 at B&H.

I only recently heard of Breakthrough myself. I had an earlier B+W that had the lens cap issue. There was no front thread either. The current product description says that it has a front thread and will take a snap on lens cap.
