Hello
I know we've had this topic not once but twice before, but the first time it was on WoS and the next time it was on Bistro, so I am bringing it back to the fore, because I finally found something that works (people had suggested a few alternatives but most did not work with the Mac. There was one that did, but I wanted to try before buying, and the free trial was windows only, so pah.
Anyway, I finally found
Hugin, which is cross-platform and simple to use, and produces good results (though if anyone does use it you MUST keep the output in Tiff format for it to blend the seams smoothly, you can always convert to your chosen format afterwards.
You just click a recogniseable part of one photo, it finds the exact corresponding spot in the next photo, you ok it, do it a few times for each photo and Bob's your uncle.
Of course, after searching all of these months for something to do the job (and Hugin is free, by the way), the very day I installed it I realised that my printer software, which I have had installed for a couple of years, also has free photo-stitching/panorama making software included in with it, and had ben installed on my computer the whole time. (duh!)
The drivers and bundles software from HP are bundled
here and available for every platform. Not being that up with computer knowledge I do not know if you can instal the software without physically having the printer, but the drivers are a free download and one of your clever lot is bound to know.
Anyway, the results are great and I made a great panorama of my back garden, but left it on my desktop Mac and so don't have it with me at the moment.
