Rotate Align

What happens if someone doesn't use a tripod or if someone photographs a leaf on a windy day and one photo is rotated slightly differently than another? Helicon Focus should be able to rotate the images so they are aligned (and crop out any area that doesn't contain each picture).

Helicon Focus can align rotation mismatches, but this option is set to 0 by default for speed reasons. But you can change this in Settings.

I did not know that! Sure it takes forever, but that's cool. Does it only slow down for files that aren't already aligned? Perhaps the program can be made slightly more efficient so it is faster.

Slowdown is not significant but for microscope and camer on thipod rotation alignment is not necessary.

You are right. Does the magnitude of the number affect how long it takes? Do the other values affect speed?

Yes, higher values increase time but logarithmically.

So 0 to 3 will slow it down, but 3 to 6 will slow it down more than double? Does this apply to the other options (like horizontal location)?
By the way, the human verification code you need to enter if you're not logged in is harder to read than it has to be. On most tries I fail because some letters are hard to tell if it's one letter or another, and I see just fine. Google's human verification is good enough for them and it's much easier to read (and it looks cooler), so I suggest changing it to something like that if you are able to.

no, it slows only a bit from 3 to 6. It applies to all autoadjustment options.
verification code: we use the plugin that comes with phpBB engine. I will check if it can be optimized.
Without verification code we had dozens of spam messages every day. Even with simple version code a couple of spammers managed to post their messages.

I understand. The same thing happened on my blog.
By the way, when I wrote, "So 0 to 3 will slow it down, but 3 to 6 will slow it down more than double?" I meant to ask if the amount of extra slowing from 3 to 6 is about double the amount of extra slowing from 0 to 3.

0 to 3, 3 to 6: no, it is less then doubled
time =k* log(max_adjustment_value)
