I think hugin is stable, comfortable, easy to use, but it's definitevely not easy to learn.With the advanced knowledge from PTgui I found the trasition easy. The
process is the same, the tabs replicating it in the user interface are
similar. The difficulties (and the inefficiencies) are at the user
interface level, not the functionality which is almost identical.
> Things have changed a lot and meanwhile it's easier than ever to start developing panoramas. Hugin (and PTGui as well) gives you a complete package and straight from downloading and installing you can start - that's really cool.Indeed, both of them do, as does Autopano Pro. I have not tried
Stitcher, but it does this too. Gone are the day of difficult installs.

I think Hugin will address this by using the ptlens database soon?!My way of working is to set up a template for a specific combo of camera

and lens. The template has been around for a while, so I was not aware
that PTgui finds the crop circle automatically. Nice for a newbie. A
template is more efficient (though it could be made even more efficient
if the stitching software would verify that there has not been a shift
of the circle).
> Using autopano-sift/autopano within hugin is fine. Best results I get using autopano-sift without ransac check. So there are wrong controlpoints I need to filter for. Usually I optimize 2-4 times and delete the points with very large values using the controlpointlist. That are only a few clicks, but a newbie will stumble on this.CP are IMHO one of the major weaknesses of hugin. Although the automated
zoom in is nice, it slows the machine down. The round circles
identifying the CPs are very difficult to read. I'd rather have a
crosshair X or something else that identifies the exact point, not the
appoximate area where it is located. Working through the list of CP is
difficult, as is manual entry of yaw/pitch/roll in the image parameters.
I do not know if this is hugin, or the widgets used for its GUI, but it
slows me down.
> The default optimization method of hugin is very helpful to detect wrong points and to bring the images into a general order. For good results you need to select another method (maybe "All" or "Custom"). Having not enough cp's, no verticals/horizontals or only many cp's, that are crowded around the center this can result in settings that are less good (Hugin reports that, like PTGui does). That's not an issue and due to UNDO etc. this can be easily and quickly solved. But a newbie would stumble here again. I think PTGui optimizes only y,p,r,b (and v?!) in simple mode to avoid those situations.I like the different preset optimization methods. I also like PTgui
granularity that allows me to select individually which parameter to
optimize when I need to do so. In my PTgui template I have it preset to
what is my usual first step. Only for difficult stitches I have to
change what is optimized. Having the ability to create such custom sets
(i.e. going further than what hugin does now) and save the set under a
name would be a bonus.
True, a newbie would stumble, but then the question is who is the target
audience. And: it is possible to have the same user interface for both
experts and newbies, as PTgui shows. The reference for newbies however
is Autopano: drop a directory on it with source images for 10 panos and
it will compose all of them with *no* user intervention. Unfortunately
it does not yet support Fisheye.
> Preview in hugin is fine and fast and automatically updated if needed - well done! It also show's you the influence of the vignetting tool!!!Yes, I liked the preview. This is where in PTgui I do numerical
transform to "frame" the view as I want it. I do not recall if this was
possible in hugin too.
> I'm thankful for the vignetting capabilities although I think this belongs into a RAW converteragree.
> In the end, the result in Hugin (using my usual technique) was better (less stitching errors) than in PTGui using simple mode. Deleting one wrong controlpoint in PTGui (using the controlpoint list) and adding 2 addional points finally leaded to very similar results.It took me significantly more time to finish the stitch in hugin, with
similar quality. IMHO stitching applications no longer differentiate on
the set of features. They all have great features and do a decent job.
What matters to me now is efficiency. Speed. Usability.
> My recommendations to make Hugin more newby-friendly:could be helpful. I'd rather see hugin using a different auto CP
> - A wizard/druid (maybe a range of wizards "Spherical with Fish", "Multirow with Rect", etc..) that triggers autopano/-sift with useful parameters, does basic optimisation and cp filtering, stable post-optimisation, comes up with a preview and shows a short report what you can do next to improve your panorama (or a button "Stitch Now?").
functionality - one that does not come with the strings attached of
autopano/-sift (there are patents in there).
> - A bad-cp-filtering-by-optimisation tool would be nice as well for advanced users.yes, and hopefully that auto CP functionality will work. I've stitched
hundreds of panos in PTgui and had seldom bad CPs. Only in two instances
(very symmetric buildings) I encountered massive problems. I sent them
to Joost and I believe he has improved autoCP in the meantime.
> - A basic HTML creation tab (just some fields for author, title, template, etc.) to create a folder with ptviewer, an html file (using a HTML template file), and the equirectangular image in would be a nice goodie for beginners too.IMHO this does not belong into a stitching tool, and there are good
authoring tools out there. Pano2QTVR takes the stitched equirect and
generates all the necessary output / formats.
What I'd like to see is HDR end to end: take HDR input pictures and
output a stitched HDR pano.
For newbies I prefer the Autopano Pro approach. No wizards. No
explanations. Just drop the folder on the app and let it run. At this
level, competition is anyway from the non-perspective corrected
stitching tools that come bundled with consumer digital cameras and not
the perspective corrected tools like the ones we discuss here.
