- Test image 1: speed and 360 sphere capabilities

Test 1:

Pictures and output dimensions:
4 shots + 1 zenital, Nikon D100, 8mm 2.8 Fisheye-Nikkor, shooted in jpg from a good tripod and Agnos Quickly QT head. Images given, the equirectangular output was set at an optimum resolution of 6000x3000 pixel.
Ptgui 4.1
Enblend 2.3 - commmand line "-v"
Smartblend 1.14 - command line empty
The machine:
Selfbuilt in a well cooled big tower case:
P5AD2 Asus based PC, 3Ghz Intel 775 dual core, 3Gb Corsair 600Mhz DDR2 in 2+2 configuration, 2 Seagate SATA 150 Barracuda200 HD, running XP pro.

originals jpg format all in one zip, including ptgui project, circa 12Mb
final smartblend jpg format, 1.6Mb
final enblend jpg format, 1.6Mb

Notes on test.

It is always important to declare all conditions and specifics of a test. You may able to discover errors on it or avoid misunderstandings. If the goal is to compare the two softwares, what is interesting is not the absolute speed, but the difference in speed between them and comparision of the results.
What I meant for speed test was to follow a very standard setup, 5 images from a 6Mpixel camera, one of which is barely used but has its amount of time consumption, that end up on its optimum size panorama.
This is not an F1 race, nor a mathematical test. Time was taken in seconds on a good USSR mechanical stopwatch, from appearing of the dos shell of the blending software to its disappearing.

If interested, I also give the elapse of time PTstitcher takes to process the 5 images (this is ment to give an idea of the computer speed, and you can make a comparison to yours).
It is around 25".

 Enblend: 2.3
time: 8':29"

A piece of a flare ghost, present and far larger on one of original images, and a piece of the head (always a piece in, when using circular fisheyes!). Please note the change in the floor texture and illumination.

img2 Little stitching error on the top! however a very good zenit came out of this stitching.



 Smartblend: 1.14
time: 1':29"
img1 Is there something wrong? the flare present in one of the original images was completely removed, as all the head pieces.
img2 Perfect!
Usually the top shot is made to save light faloff and poor border quality. And usually pttools lets it apart. I do not comprehend how it decides the seams shape. However here smartblend did the miracle.
