Why did you require such a large end file size? rm > Why did you use 2 focal lengths to record the image? At 400mm there are regions where you get nothing but (almost) black sky, which gives no point of reference for the panorama software to be able to join the photos. Using 200mm for those areas, and overlapping them with points of reference from the photos takes at 400mm solves that problem. Of course, this means that the areas taken at 200mm (eg, the top left corner of the image) are interpolated, but as there's no detail in these areas that's not an issue. > Why did you require such a large end file size? That's something you'll need to ask Adobe! Best I can work out .psb files don't have any form of compression. Saving it at a compressed TIFF over halved the filesize. Using jpeg wasn't an option as it's above the maximum resolution that jpeg supports. Scott >> Why did you require such a large end file size? > > That's something you'll need to ask Adobe!

Irfanview can write both, but the JP2 writer isn't free. Both need browser plugins to view. > http://www.docbert.org/SydneyByNight > > Enjoy :) > > Scott Just as another question why does your arrow buttons (on the image)work in reverse? It doesn't. After enlarging, the left arrow moves you left in the image, likewise the right, up and down arrows move you right, up and down.

Any tips about how that was done? Colin D. SignaturePosted via a free Usenet account from http://www.teranews.com |
