Ack! Think I said it once before - PNG is better than TIF for stuff like this, if you want lossless compression. Ok, someone once said that TIF allows all kinds of extra information to be embedded in the image, but really, if you're not going to need the extra info, go PNG! Smaller than TIF, with none of the quality loss of JPG.
Got to wait until I'm home from college next week to download the huge TIF file. 1.5GB/week bandwidth limitation here, and I can't afford to take a .46GB chunk of it all at once.  Thanks for the link though.

I'm just curious Jeff7...What are you going to do with that image in TIFF (or PNG) besides looking at it? Why do you need that enormous file at all? Are you planning to make a wall-sized poster of it? -------------------- The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.

Ofoto is having a half-off special right now for 16x20 and 20x30 prints. I got about 10 of each for various Galileo, Cassini and MER photos. I plan to back them with foamcore and either hang them in a hallway in my office or in my garage at home. Several of them are reverse mosiacs, with the largest a 4x1 20x30 mosaic (10 feet long!) of the view from the summit.
This image is perfect for making a single 16x20, or a mosiac of YxY 16x20s. I find it amusing that everyone here takes a bunch of small pictures to make one big one, while I take a big one to make a bunch of small ones... With 16x20's around $10, I might either do a 2x2 or 3x3 of this. This would be an awesome picture 48"x60", or 4 feet x 5 feet! The problem is that most images aren't nicely fitted to standard photography dimensions of 8x10, 16x20, or 20x30. What I do is use GIMP to expand the image to the proper X/Y ratio, and then chop it up into multiple parts. Did it once before with the Endurance pan with 8x10, should be interesting to see what happens with 16x20 and 20x30! Once I get them in and all mounted, I'll post a photo of the setup. -------------------- Space Enthusiast Richard Hendricks

And maybe it's just an obsessive thing of mine - I like file compression, but I don't like lossy compression. For example, I reripped my entire CD collection to FLAC instead of MP3. |

Pity they missed a bit with the mosaic that appears to be stuck on a reference background

For those just interested in ordering prints, here is the KodakGallery share: http://www.kodakgallery.com/I.jsp?c=qqit9s...j&x=0&y=-6ta1sq The 16x20s can also be printed in 8x10 to keep the proper aspect ratio. The 20x30s can also be printed in 4x6 to keep the proper aspect ratio. The 50% discount on large formats expires 3/8/2006 -------------------- Space Enthusiast Richard Hendricks
