**OK, I'll take a look and tell you what I think. --[[User:Jjron|jjron]] ([[User talk:Jjron|talk]]) 16:10, 11 April 2008 (UTC)

**Have had a go at the restitch. The originals were pretty low res, so the restitch is considerably smaller and lacks some detail, but it is a bit better. I checked the original pano fullsize, and it was full of stitching errors, some pretty bad, and it was pretty noisy. <br>The restitch is better (I noticed one stitching error which I didn't fix), and it still tilts a bit, mainly where the water goes across the horizon, but the really bad stitching faults are basically gone. I also did a noise reduction to take out some of the grain, but as I said one negative is it is a bit lower in detail than your pano. I'd suggest trying again with the full res originals if I thought it was worthwhile, but if you're mainly thinking FPC I'm quite confident it wouldn't make it anyway, working off these originals, I'm afraid. There are some problems in how they've been taken which kind of limits what you can do. <br>Can I just make some suggestions for next time you shoot a pano, or if you have a chance to reshoot this one. I'll assume some of the problems in the originals, such as jpeg artifacting, were more a result of the downsize you did than the camera itself. This camera should be able to take decent images, despite it being a few years old now. Having said which these Panasonics are notoriously noisy, though at ISO 80, which these were taken at, that shouldn't usually be an issue. Where possible set controls manually (some of these settings may have been manually done?); however the exif suggested it was auto exposure and some of the settings altered slightly in different images. This really all seems a bit dull and if you were setting it manually you could have upped the shutter speed to probably half of what it was (or changed the ISO, but with this camera probably better to keep that as low as possible). Also one of the big problems here is that a number of the images are badly tilted. It is best if you can use a tripod and just rotate that across the scene, instead of taking the shots handheld where you get inconsistencies. The different tilts from image to image is probably the biggest reason your stitching software has struggled so much, and why we get the horizon tilting even in my edit. I actually straightened the originals before stitching, but it still wasn't enough to avoid the bit of a tilt, and has probably cost a bit of height. You could also try shooting in portrait orientation rather than landscape to get more height. I'll leave it there. It can be tricky getting things right for these panos but it can be fun to keep trying. Cheers, --[[User:Jjron|jjron]] ([[User talk:Jjron|talk]]) 14:37, 12 April 2008 (UTC)
