Took 4 frames (Canon 20D and 17-40 f4 L lens) and used Autostitch for the pano. Comments?

A very nice atmospheric image. It would benefit from being levelled properly. This is difficult to do in Autostitch, but its big brother AutoPano Pro or PTGui can do this easily. You make use of the fact that an object and its reflection in level water will be exactly vertically aligned. There are therefore lots of features here that you can put vertical markers on. The vapour trails are unfortunate too. They can probably be invisibly removed using Photoshop's patch or clone tools.

Anyone know the difference between the two commerical versions (AutoPanoPro and PTGui)? There is a signifcant price difference I understand.

PTGui has been around several years and until recently was simply a front
endinterface program for the Panorama Tools package. PTAssembler,
Hugin,PanoWizardand PTMac do a similar job. It's primarily a manual stitching
program, and extremely versatile. TheAutopano and Enblend plugins came along a
couple of years ago to add a degree of automation the process. In the last year,
PTGui has reduced its dependency on Panorama Tools and the plugins by including its
own control point generator, optimizer, stitcher and blender, so that it now hasa
good performance as an automatic stitcher. It is still possible, however, to mix and
match the various features of the new programs and old Panorama Tools software,
according to requirements. For instance, the new PTGui software has opted not
tohandle extreme wide angle lenses like fisheyes (probably for legal reasons), but
Panorama Tools can be called upontoprovide that functionality. A full range of lens
types is supported, including cylindrical and equirectangular. This means that PTGui
will accept its stitched output images as input. PTgui will happily "stitch" single
images for the purposes of levelling, correcting converging verticals, and remapping
from one projection to another - e.g. defishing fisheye images so that programs like
RealViz Stitcher can handle them. So all-in-all, a very useful program that is
capable of the highest quality stitching, though it does take some time to learn how
to use it effectively.

Autopano Pro is the new kid on the block: an automatic stitcher, capable of high
quality stitching. There's significantly more control possible than with the free
Autostitch, but not as much as in PTGui. It cannot yet handle fisheye lenses or stitch
single images. It doesn't always work properly, though most of the time it does a
good job. When it fails tostitch properly, there are no manual facilities to fall back on
to retrieve the situation. If it only finds half a panorama in your set of images,
there may not be much you can do about it. PTGui will stitch its failures!

Thanks, much for explaining the differences in the two programs.

I've not used Autopano, and I have an old version of PTGui so I can't comment on those differences, but one of the most powerfull advantage of PTGui (and the other Panorama Tools GUI front-ends) is the photoshop layers output. Thatallows youto adjust the stitch line so it lands in less noticable places.(The mulit imageTIFF outputwill work with editors that support layers, but not PS layers, albeit with more work). If Autopano does not have that feature, I would countthat as a fatal stike against it as a truly powerfull program.

style="BACKGROUND-COLOR: #000000"That does not mean you should ignore Autopano or other automagical stitching programs. They work fast and do a good job in many situations. Having a simple, easy program is not a bad idea,but sometimes you will need more power.

Bill, Autopano Pro does provide a layered PSD output file option, though no masks. Oddly, it doesn't have a TIFF output option, though it will do PNG and it will accept TIFF input files.

Nice shot. Autostitch really does the job, especially when you consider the price.
