1st_Replicant Posted January 21, 2019 Share Posted January 21, 2019 (edited) I`m not able to get the JPG file size of 17 MB. Camera: FUJI X-T1 Original RAW - file size: 33,7 MB Exported as TIFF 300dpi - file size: 42,8 MB Save as JPG 300dpi (compression at highest Quality 100% or Level 12): 11 MB I tried both Capture One Pro and Photoshop - same results in 11 MB. So how can I export my RAW-Files to get the "minimum 17 MB" condition? Edited January 21, 2019 by 1st_Replicant Link to comment Share on other sites More sharing options...
spacecadet Posted January 22, 2019 Share Posted January 22, 2019 17MB is the minimum uncompressed size. You're quoting compressed. Link to comment Share on other sites More sharing options...
gvallee Posted January 22, 2019 Share Posted January 22, 2019 From Alamy guidelines: File size of over 17MB (when uncompressed/open) Your JPEG file is likely to have a compressed size of 3-5MB. Opening a JPEG in an image program such as Adobe Photoshop will show you the uncompressed/open file size. Link to comment Share on other sites More sharing options...

So how can I export my RAW-Files to get the "minimum 17 MB" condition? The Tiff you have shows you the right size in MB. The instruction says: uncompressed. Jpegs are compressed, but even Tiffs can be compressed, this is not the case with your file. Normally the size of an image or a camera is given in megapixel (MP). Not here however. The X-T1 is a 16 megapixel camera: 4896x3264 = 15,980,544 pixel - say 16MP. Saved as a 8 bit uncompressed Tiff, that's your 42,8 MB. If you take your Jpeg and save it as a 8 bit uncompressed Tiff, then again you'll have your 42,8 MB. Albeit with the loss of some quality depending on the quality setting when saving it the first time as a Jpeg, because it uses a lossy compression. Hence anything better then 3000x2000 pixel = 6 MP is 18MB is good enough. When Alamy started many years ago it used to be 48MB if my memory is correct. wim Link to comment Share on other sites More sharing options...

Bundles of CDs with 14 48MB Tiffs (up-res from 6MB camera) in the post from Canada. I think it was 20 images to pass QC to be accepted then, its down to 4 now.

But that may have been the initial submission only. There's maintenance going on at the Wayback Machine, so no way of checking any of that. wim Link to comment Share on other sites More sharing options...
