Graeme Matthews Posted May 5, 2022 Share Posted May 5, 2022 HI, I have just joined. I see that photos submitted need to be 17MB. I have 3 cameras. 1. Fuji APSC seems to upload about 13.5MB 2. Fuji Medium Format seems to upload about 14MB for Jpegs 3. Sony A7R2 , with 42mp, seems to upload about 21-25 MB How strict are the guidelines that photos need to be at least 17MB? Thanks, Graeme Link to comment Share on other sites More sharing options...
sb photos Posted May 5, 2022 Share Posted May 5, 2022 The 17mb is the image open size, not the physical file size as you have likely quoted. As an example I've just uploaded a batch of jpeg images 4000 pixels on the longest length with a physical file size varying from 7.6 to 10.5mb, but the all important open file size in photoshop is 30.6mb. Generally from my Nikons an image file around 3000 x 2000 pixels would open to 17.2mb, just within Alamy's minimum for stock images. Welcome to Alamy.

gvallee Posted May 5, 2022 Share Posted May 5, 2022 https://www.alamy.com/contributor/how-to-sell-images/guidelines-for-submitting-images/?section=3 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. 1 Link to comment Share on other sites More sharing options...
M.Chapman Posted May 5, 2022 Share Posted May 5, 2022 As an easy to remember rule, just make sure the images you upload contain at least 6 million pixels and you'll be fine. e.g. 2000 x 3000 pixels Mark Link to comment Share on other sites More sharing options...
