Adding a nadir logo with text

I made a tutorial for this.

See at: Creating a mirror ball cap with remapped text

This tutorial will be available here soon.....

For what it is...

The equirectangular projection is the starting point of several products.
This projection is extermly streched at zenith and nadir. An insertion of
a logo text isn't possible in one go or it looks distorted. in this tutorial
I show you a way to create such a remapped text that can be inserted directly
in an equirectangular panorama. The other advantage is that with this text you
don' need to remap the whole panorama. Every transformation results in quality
loss.

What do we need...

• Photoshop or a software that can run Photoshop actions (f. e. Gimp Win, Mac OSX, Unix )
• An equirectangular panorama (PSPhere, f. e. 6000 x 3000 pixels)
• Panotool plug-in for Photoshop created by Thomas Niemann (download here)
• Batch file to produce faces from an equirectangular pano(Pano2Faces.bat) and vice versa (Cube2Pano.bat) from Eric Gerds (download here)
• Photoshop action to create the mirror ball cap with white text plate (download cap_text.atn)
• Logo text as Photoshop file (download LogoText.psd)

Creating a pano with nadir cap

For this step you need the Photoshop action cap_text.atn to produce the
white plate for the logo text.



You have to stop the action when you areasked for the remapped text file.



Keep in mind the original size of your panorama (f. e. 6000 x 3000 pixels)
You will need this value later.


After this step the modified panorama looks like this:




You see a white area where the logo text will be inserted.

Remapping nadir

Here you can find two different ways to extract the nadir view for inserting a logo:

1.) With Panotools Plugins
2.) With extracting cube faces

Remapping nadir with PanoTools Plugins

First turn canvas by 180 degree:




Run Panotools plugin PTremap (Filter/ePaperPress/PTRemap):




With these settings and values below:




When you hitting button Prefs (Image above) it should look like this:



Whith these settings the remap plugin saves the remapped image in a new file.
This is really important because with every transformation of the panorama it
will loose quality. In this step we need only to see the mesure of the white
plate to transform the logo text to the right size.


The remapped view in which you can see the small white circular plate in the middle:




And here with a closer look:




Now it's time to be creative and think about your logo text.
Or you take the way trough an additional method to extract the nadir view.

Inserting text

Remapping text back to PSPhere

Here you can find also two different ways to remap the logo text back to PSPhere (Eqirectangular projection):

1.) With Panotools Plugins (These steps have an addiotional transformation to the text because the plugin alter the size of the file while transforming)
2.) With extracting cube faces

How does it works now (PS action)

End of wiki tutorial

CapText_001 1. Run this action in Photoshop and keep in mind the original size of the opened panorama:

CapText_002 2. When this message pops up, click to cancel the action...

CapText_003 3. This is the result from the action till this point (the grid is set to 50%):

CapText_004 4.Turn canvas by 180 degrees:

CapText_005 5. Run PTRemap Plugin as shown below:

CapText_006 6. These settings under Prefs will generate and open an additional, remapped file:

CapText_007 7. Settings for the remapping job:

CapText_008 8. This is the resulting remapped view, looking straight down:

CapText_009 9. Here a little bit more zoomed in:

CapText_010 10. Open a prepared Photoshop text file to fill in like this (for download see on top):

CapText_011 11. Drag and drop the text file over the remapped pano until it fits well as shown below: (to transform the text hit ctrl+T)

CapText_012 12. The text layer should be on top and selected. Don't flatten it to background nor reduce to one layer!

CapText_013 13. Run the Remap plugin again:

CapText_014 14. Settings to remap back to equirectangular projection (PSphere):

CapText_015 15. This is the remapped text without the pano as result from the remapping process:

CapText_016 16. These are the values from the remapped text file:

CapText_017 17. Change the values to the original size of your panorama. Mine was 6000 x 3000 pixels:

CapText_018 18. Turn canvas by 180 degrees again:

CapText_019 19. Duplicate background to a layer and delete original background:

CapText_020 20. Delete the white colour by selecting it:

CapText_021 21. In this dialog pick the white colour and click OK

CapText_022 22.This is the selected white colour (You can do this also with the wizard stick tool)

CapText_023 23. Delete the selection and only the needed text will stay (yellow highlighted): Save this file for further use with this Photoshop action and give it a name which includes the size of the file, really helpful!)

CapText_024 24. Now you are able to drag and drop this file to the panorama by holding shift key (It should fit exactly in the white area in the panorama picture):

CapText_025 25. After the step above flatten the layers to backgound:

CapText_026 26. Save as.... (ctrl+shift+s) .... done!

CapText_027 27. This is the resulting nadir cap with text:

Next time when you run the action on a panorama with the same size you don't have to cancel it, because you can use the above generated, remapped text file. Now you are able to produce this nadir logo in one go. You just have to guide the action to the remapped text file and your computer.
