Advertisement Posted May 24, 2008 Posted May 24, 2008 Hi JHAG, Take a look here Big files required . I'm sure you'll find what you were looking for!
kbingman Posted May 24, 2008 Share #22 Posted May 24, 2008 Ah... Alamy. They are indeed not referring to the file size of the JPG, but the actual pixel size when the file is opened in Photoshop. Jpeg file sizes can vary a lot, depending on the content of the image and the quality of the impression. Alamy is just asking for a specific minium pixel size. Getty has similar sizes, with "48mb" being one of the standards. Once the file is saved, if you use a good quality, it should be around 4-5mb, but like I said, this can vary. I have a few images on Alamy and they all met their requirements. I haven't looked there is ages, though. Keith BIngman Link to post Share on other sites More sharing options...
lct Posted May 24, 2008 Share #23 Posted May 24, 2008 They say "Minimum uncompressed file size of 48MB". So the 50.2MB file of my chart above is OK no? When compressed level 10, makes a 8.3MB jpeg according to their specs as well ("maximum compressed file size of 25MB"). Link to post Share on other sites More sharing options...
JHAG Posted May 24, 2008 Author Share #24 Posted May 24, 2008 Right, lct Is it me, or these Alamy gentlemen are artists in abstruse specs ? Never had so much problem to understand spec sheets (sse Photoshelter, a model of clarity). Link to post Share on other sites More sharing options...

JHAG Posted May 24, 2008 Author Share #26 Posted May 24, 2008 Both perhaps? I'll accept a 25/75 at most. Link to post Share on other sites More sharing options...

mhulbert Posted March 4, 2009 Share #28 Posted March 4, 2009 In PS start with your RAW shot convert to 16 bit save as a TIFF do your adjustments (make sure zero sharpening) adjust size on longest edge to 5128 (which is about 100MB) then change to 8 bit (about 50MB) save as a JPG voila -- a compressed size of 5 - 8 MB, uncompressed around 50 MB (bows and leaves the stage) Link to post Share on other sites More sharing options...
tobey bilek Posted March 4, 2009 Share #29 Posted March 4, 2009 Raise the resolution to 300 ppi or 600 ppi or what is required. It will still be the same size, but have bigger MP. The site is under the false impression there will be more quality with less storage space. Humbug! A small high rez file take the same space as a lower rez larger dimension file.

andit Posted March 5, 2009 Share #30 Posted March 5, 2009 To me it sounds like they are limiting there site to images taken with medium format equipment like those on a Hasselblad with a 31/39/50 megapixel back. I know that in the older days some stock agencies stipulated medium format images, with 6 x 4.5 being the minimum size, but with 6 x 6 and 6 x 9 being preferable. Fashion shoots would never even look at 35mm unless it was for quick and dirty work (just to run off some postcard size prints). Andreas Link to post Share on other sites More sharing options...
