My Autopano Pro forum

doesn't look bad to me.

Try using different anchors.

signmaster what you showed looks like an error during postprocessing. APP always exported 360° equirectangulars for me with no color mismatches at the edges (except for  zenith and nadir when using smartblend), so what you showed looks like somewhere along the way AFTER rendering when you were postprocessing your image you used a tool that was not designed for panoramas and it didn't blend across the -180°/+180° border. It could be in Photomatix like klausesser said, or caused by other programs like Photoshop.

You can fix this by taking the left ~10% of your pano and copying it to a new layer, do the same with the right 10%, put both layers side by side and merge them, then heal or blur out the difference so its graduated, and then slice that 20% wide layer into two 10% layers and put them back in their places... or instead of all that you could shift your pano along the x axis by any amount (e.g. 50%), then heal/blur, and shift back.

Screenshot below pinpointing the not-too-obvious error.

Thanks very much for the prompt replys.
I need the images as a .hdr for 3D illumination.
The problem is not post processing, not doing any. I can stitch a single group of the bracketed set in Autopano and not have the problem. It is only when I stitch a bracketed group in one operation as per http://www.autopano.net/wiki/action/vie … _panorama. The problem is still there if I take one of the three resultant stitched images, say the correct exposed stitched image and using Pano2QTVR to convert the image to a 360 degree Quicktime. By doing this I think I have isolated the problem to Autopano Pro?
I would like to solve this problem as I am trying to develop the best and quickest method of creating stitched HDR images for 3D illumination.

Does the same problem exist if you do the QT conversion with Pano2VR rather than Pano2QTVR?

Yes exactly the same.

You are outputting a separate layer for each bracket step from APP?

Yes seperate layer for each bracket step.

Can you show us a screenshot of the overlaps in your pano from the pano Editor?


Screen shot below.

Thanks for the help

What pano head?
Half home made with RRR MPR-192 and clamps

What pitch is the main row shot at?
Main row 4 photos at 90° about 15°up one shot down (nadair)

How are you shooting the bracketed nadir shots?
Hand held

Maual focus? Yes

Manual exposure? Yes

Custom WB? Set in RAW (will check as I sometimes forget) Should this matter as the seam is actually up the center of an image?)

Which blender?  Which color corection mode (LDR, HDR, none?)
none

What anchors do you use?
I am new to Autopano, not sure what you mean by "anchors"

This could be caused by vignetting.
If I convert one of the resultant images I don't have the problem??

8mm sigma, 20D
4 shots around (bracketed) up about 15°
1 shot down hand held (bracketed)
Manual focus and exposure, in RAW
Lightroom set white balance to same setting, export to tif
Stitch in Autopano Pro output to set of 3 images (if I render one of these images in Pano2QTVR I have the problem.
I then produce a HDR file and a tone mapped image for QTVR

I might not be back for a week as I am going to Bangkok, madly working out what gear to take, don't think I will take my tripod, but will try some hand held panos, I often find they stitch better than those shot with my pano head and tripod.

DrSlony,

This is sort of related to hw in that an 8mm may Vingette, even on a APS sensor.  The line is where one edge of one image overlaps the center of another, even if you use manual exposure, vignetting may cause a stop or two difference.  On my Sigma 12-24mm at 12mm, I get some vignetting even at f/16, but that's on a 5D. 

signmaster,

research "optical vignetting".  Also, as DrSlony says, use color correction.  This will get rid of the vignetting. 

BTW, what aperture did you use?  The wider, the more vignetting.
