blue/grey band problem

Does anyone else have the problem of a dark blue/grey band appearing around the outside of images (pre-stitching)?

I'm shooting indoors (for 360 tours) using an olympus d-490 zoom and olympus FCON-02 fisheye.

Before I scrap this outfit and buy the coolpix - is this going to be a problem with the coolpix too?

Any coolpix users have this problem?

Similar blue/grey bank appear in the image shot with Coolpix DC and FC-E8 fisheye images. Sometimes it is very thin, sometimes it is rather wide. Please send me your image and let me have a comparison if possible.

This band is very wide - but now I think I can get the software to cut it out. Here are sample images (pre stitching):

And here is a stitched result:
http://www.3604u.com/blueband/7-8.html Still shows a little but not bad.

Not thrilled with the image quality of the olympus d-490z/FCON-02 fisheye - grainy and blurry.

What camera & lens are the panos at http://easypano.net/examples.htm shot with?

Some examples are shot with Nikon Coolpix995+FC-E8 fisheye lens. Such as Living room 1 and Living room2. Others are from our customers. Also most of them use Nikon Coolpix995+FC-E8. But there are someone use Nikon Coolpix500+FC-E8.

I use a coolpix 800 and a nikon fc-e8 I get the banding too under bright sun light I was able to minumize it using rainX UV on the front surface of the lens. The other issue with the bright light is intralens reflection. I have checked out about every available conventional lens and camera combination. The next step for me is a scanning camera like the Seitz original round shot not the D1. I plan to build one myself soon using a usb powered scanner.
The world needs perspective.

I too using the 5000 and the fisheye get the banding... It's a shame because it adds time to the whole lenth of process of creating the vr

There is such an article in panoguide about retouching fisheye images before stitching: http://www.panoguide.com/technique/optimising_fisheyes.html .
