I think the centre photo is darker, only due to the speed being at 1/640 second. Unfortunately, Irfan view did not carry over the exif information from raw to tif format, however, below is the list of most of the Irfan view interpretation of the original raw file information. PS - I think it was a guy named 'Chubby Checker' who had a hit single back in the 60's 'Let's stitch again, like we did last summer' (well if you can remember the 60's, you weren't there -)) I'm hoping this will turn into a sort of tutorial, on various methods of stitching images, so if you just post your results, without saying the steps you took in order to get there (so that we can repeat the process), then you will have missed the real objective of this thread. I am not concerned with sharpening, or other manipulation, but I would like the resulting stitched image to show the path with the cypress trees to be straight, and not curved, if possible. Even I was able to virtually immediately produce a good enough result to persuade me it was worth the effort to resize the images, etc., and upload them for you all to try. There is no need to upload a high resolution result, since the idea is that we can follow your steps and produce a similar result on our own local machines, if we wish - it should be that simple. (I think panowizard may be pc based only, but I expect similar software exists for other platforms). The task is to use this software, or other low cost software to produce a panorama, and describe the steps involved to produce a stitched panorama. No processing has been done to the files, other than using Irfan view to convert the original cr2 file to tif, and down size them. They are six images taken from one position, iirc, with no particular intention to make a panorama. You will need to download them to your pc in order to work on them.) The last image - all.tif - is composed of the other six images laid out in order, but obviously not stitched, and is provided to show the image sequence, and to indicate that the contrast is not consistent over the range (a common problem to be solved). (They are tif images, your browser may not render them. These are photos, taken earlier this year of an area of a formal garden. So, if you go open the directory at you will find 7 tif files, each file being about 1.2 MB in size. However, I believe the software is good enough to produce acceptable results with images that were not carefully taken, so I have started this thread hoping that we can learn just how this process can be so easy. Bart gave a link to some software, which is indeed easy to use and can give accurate results if the initial images are carefully taken. It was mentioned that the modern software allows easy and quick stitching of images to produce a digital image that can easily exceed the resolution of a lf film image. In another thread, there was discussion comparing the benefits of large format film compared to stitching of smaller format digital images.
