Is my equipment wrong or...?

Hi - I am using a Canon Powershot 9G with a Besel Super Fish_eye 0.25X and a NodalNinja 3 II panohead.
BUT when i stitch my 3 images i get a black triangle in top and buttom - and the stitching isnt very good - I use the standard settings....

When dooing the same with my Nikon Coolpix 5100 and Fish-eye E9 - there is no problem...

The black triangle at the panorama top are really the top convergence of the 3 image.

You can try tilting your lens up 3 - 5 degrees to remove the triangle.  OR  you can cube the image and photoshop the black triangle out.  Tilting up to close the image tops  will of course cause the tripod triangle to be larger.  But that is ok because - use a Floor or nadir tripod cap to cover the panhead and tripod.

We use a Canon 20d and a 350d  and a Sigma 8 f/3.5 lens and take 4 images.  So we get a small black square.

Ah  that's an easy question to answer. 

ANYONE who "Just back from a 2 week (2,000 shots/30+ gigs) photo trip in Arizona"  deserves to know this trick.

You just have to have the right tools.  Go to the kitchen and get some plastic food wrap, and a magic marker, and a pair of left handed sissors. !!!!! LOLLL NOT today he wrote.  BUT its just about that easy.

Your favorite photo editor that can handle transparent background canvas, and layers.  Photoshop CS3 is my favorite so I will talk from there

I suspect you are using Panoweaver 5.  PW 5 has a function called a FLOOR image.  The tripod cap transparent .gif  file will go into the /floor folder.

In photoshop open a new file, tell it to have a transparent background.  Make it (depends on your tripod leg spread trial and error) say 300 x 300 pixels square.  New layer over transparent background create a color filled circle.  New Layer over color filled circle  for TEXT or image.

Save as new file name.psd.  Save again for WEB and devices filename .gif  transparent 256 GIF.  Put this file in the Easypano /Floor folder.

In PW 5,   import your panorama.  click on the /FLOOR (right screen side)  select your transparent gif tripod cap.  And Watch PW5  warp the new T-cap circle across the panorama bottom.  Save the new version of the panorama.

When you preview .. you will see the dewarped tripod cap circle when you tilt down.

Hope that helps

I would like to add that if you save for the web as a .png it should help eliminate the jagged edges of the circle.

If you know the "secret" then everyday is a good day!
