I have a 2 pictures (70% overlap) that I cannot align properly.

I manually fine tune the parts that ghosted, which actually are only 3-4 squares. After everything looks fine on the screen I press Close-button and the image is blended but the ghosting comes back. Just like nothing had happened compared to the original stiching.

If I open the overlap region again the picture looks fine, I just can save the manual fine tuning.

I've tried to look the online help and faq, but couldn't find a solution

I don't know what's causing this problem, but I'd like to find out.

I'd really like to try to reproduce your problem here on my own computer so that I can see exactly what you are talking about. I'd like you to send us a copy of your stitching project, immediately after pressing the "Close" button on the fine tuning.

It would be best to do this through our customer support system.

Could you please email your question to support@panoramafactory.com so that we can open a dialog through email?

Here are the specific instructions on what I'd like you to send:

1. Stitch your images the way you normally do (using the Wizard or the Classic interface).

2. Manually fine tune the images and press the "Close" button.

3. When you see that the ghosting has come back, save your project file using the "Save Project As" command from the File menu. Let's suppose you save the project file as "myproject". This will save a file called "myproject.pfp" and also many image files with names like "myproject_imported_1.jpg", "myproject_stitched_1.bmp", "myproject_cropped_1.bmp", etc.

4. Please send the file "myproject.pfp" and all of the "myproject_imported_..." files as email attachments to support@panoramafactory.com. You don't need to send the stitched, cropped, etc. image files or any of the thumbnail images -- only the imported image files.

NOTE: If the mail attachments will be larger than 1 megabyte in total, you should send them to us via FTP instead. Please contact support@panoramafactory.com for instructions on how to reach our FTP server.

I look forward to receiving the project file and imported images so that we can investigate this problem further.

I apologize for the delay in answering this question through the forum. Jukka and I continued the dialog through customer support (support@panoramafactory).

After analyzing Jukka's stitching project, I determined that the problem is a variation of the one described in the web page A fine tuning challenge.

This web page describes how the automatic fine tuning misbehaves when areas of the image lack sufficient detail. The example images shown on the web page contain large areas of cloudy sky and snowy foreground. Jukka's images show a lakeshore with trees. There are large areas of cloudy sky above the trees and watery foreground (surface of a lake) below the trees.

In these images, the automatic fine tuning produced incorrect results in the surface of the lake. Many of the water tiles were inconsistent with the rest of the image. Large areas of water or sky sometimes have this problem.

Although Jukka corrected the fine tuning tiles in the area of the trees, the incorrect fine tuning of the water affected the results even in the tree area. This problem is explained in more detail at Why a little editing may not help.

It is unfortunate that bad tiles have an influence on distant areas in the image. We are working on improvements to the fine tuning to make it less sensitive to this type of problem. We hope to include these improvements in a future release, probably V4.0. Until then, you must use the techniques described in the web page A fine tuning challenge when this type of problem arises.
