Part 5: Assembling the Images
Without the zenith-image this step would be very easy: Set
"TIFF" as "File Format", use "Enable Enblend" ("Plug-in Menu") and there we
go. Unfortunately there is no automated way to use Enblend for inserting the
zenith image flawlessly.
We have to use the DOS shell to assemble images in a
Go to the tab "Create Panorama".
Hopefully, we have set "File Format" to "Multi-image TIFF".
Creating Fullscreen VRs I recommend an output size of at
least 4000x2000 as a good compromise between details and file size. Perhaps
this recommendation will not fit your needs - especially if you use a
camera with less than 4MP resolution.
After some calculation time you should get 5 TIFF-images.
Each one has your output name plus a 4 digit suffix.
We will now use Enblend to blend the images. To simplify the
workflow, you should
download this little batch file into the directory of Enblend (right
click and "Save as"). This batch file will allow drag and drop operation
Drag the first 4 images (the horizontal row) over the
While running, the program will see something like this:
After some calculation time you will get back a blended image with the

of the batch file:
- Go back to the tab "Panorama Settings" and use "TIFF" as

images" only select the first 4 images. Generate the

Return to "Create Panorama" to the "include images" box.
Only select the last image. Generate the Panorama. A warning
will appear the the image already exists but you can safely
ignore this message.
This only works with the most recent version of PTGui (3.7).
Finally we have to add the zenith-image.
Open your favorite image-editor (has to be able to use layers, e.g.
Photoshop). Create a new image with the size of your final panorama. Load
the blended image, copy it and paste it to the new, empty image. Reduce the
image to the background layer. This will help you to get rid of the, now
superfluous, blending mask which would cause some problems in the final
Now paste the zenith image over the panorama. Add a layer-mask (mask
all). Now you can paste the required parts of the zenith to your panorama
(use a white brush!).
Again reduce to background layer. Now is a good time to adjust Brightness,
Contrast etc. and eventually Sharpness.
As final step, save the panorama as uncompressed TIFF.
|There is also a very elegant way to blend the zenith
image with the help of Enblend. You have to do some manipulations of the
alpha mask which I have
