DaveEP Posted June 15, 2007 Share #1 Posted June 15, 2007 Advertisement (gone after registration) While on vacation last month I spent quite a lot of time taking 'pano' shots. Today I got around to stitching the last and largest of them all. This worked out at 424 megapixels (!!), with dimentions of 43350 x 10250 pixels. Great! Now to save it. Hmmm... no JPEG option available! WTF? So, as a warning to all out there, the JPEG limits (in Photoshop CS3 at least) are 30,000 pixels per side, and YES you CAN bump in to this using an M8 !!! Saving as an 8 bit TIFF with compression gave me a 470MB file! Ouch! One shot per CD! Below is the bottom half (!) of the pano, and a 100% crop of the stern of the cruise ship on the far left side...... all unsharpened.... M8 + 135 apo @ f8 (originally shot raw - and yes the hull of the ship is a navy blue and not black ). Link to post Share on other sites More sharing options...

35mmSummicron Posted June 16, 2007 Share #2 Posted June 16, 2007 i believe you are correct in that the JPEG file format limitations are 30,000 pixels per side. if i remember correctly an improvement in Photoshop CS2 is the ability to work past that, upto 300,000 pixels per side, but obviously working in a different format. you can always use lossless TIFF compression--i use LZW all the time, and is MUCH MUCH MUCH better in preserving file quality than JPG, especially in large images where you need the picture to hold up. /a Link to post Share on other sites More sharing options...
DaveEP Posted June 16, 2007 Author Share #3 Posted June 16, 2007 Thanks Andy. LZW TIFF is what I used. Normally I would save this stuff in PSD initially (due to layers etc), but even that wasn't possible, and it saved it in some 'large image format' file instead!

Cindy Flood Posted June 16, 2007 Share #4 Posted June 16, 2007 Nice job on the pano, Dave. What kind of tripod equipment did you use to make the pano frames? Link to post Share on other sites More sharing options...
DaveEP Posted June 16, 2007 Author Share #5 Posted June 16, 2007 Nice job on the pano, Dave. What kind of tripod equipment did you use to make the pano frames? These shots were all take hand held. At this sort of distance you really don't need a pano head to do a good job. While I do have a pano head, a Manfrotto 303SPH, I almost never use it, because it's too big to travel with in, unless you have a specific shot in mind. I may even sell it Link to post Share on other sites More sharing options...
