"Any sufficiently advanced technology is indistinguishable from magic." -- Arthur C. Clarke
Some photographers pixel-peep to measurebate, but regular people will happily pixel-peep simply due to the "wow" factor. And there's a legitimate place for a little drama in showmanship and sales.
Although I haven't yet tried the IrfanView conversion, I did manage to get my first test file onto my tablet by simply cropping off part of the pano to make the overall width of the image under 30K pixels (total 295MP). Saved it as a JPG, ended up with a 72MB file. Works fine. Loads in a couple of seconds on the tablet. Pans and scrolls a little more slowly than other images, but again fine.
Besides, I love the results! I've shown it to almost a dozen people this weekend, with uniformly great effect: I start by zooming in to full detail, and I show them the image... they like it. Then I tell them it's actually part of a larger image, and zoom out somewhat... they say "wow" and they like it. Then I do that again, two or three more times... and the "wow" gets bigger and the grin gets wider. By the time I show them the full pano, they have a clear idea of just how much detail is in that image and they're asking what kind of interstellar camera I used to get the shot.
Of the people who saw the file this weekend, two chose to buy a print... call that 12% or so. At $500 each, that's already a huge success as far as I'm concerned. This is definitely going to be a part of my standard workflow going forward. I think people are reacting very positively because the zooming in to show the detail helps them understand what the large print would look like on their wall.
