Just a quick reference post to share some charts showing the most common file sizes and resolutions of images (photos and illustrations) distributed by Microstock contributors through picWorkflow.
File sizes of JPEG images distributed to microstock agencies
Interesting to see that 80% of files are 10meg or less, and on a steep curve. Whereas the megapixels show a broader distribution across a range of sizes.
Resolution in Megapixels of JPEG images distributed to microstock agencies
Interesting here that 12 and 10 megapixels dominate the chart (the most common prosumer DSLR resolutions) with 6 not far behind (the lowest size for each image to be acceptable to all agencies).
Not quite sure why the large number of images at 39 megapixels (it’s actually 38-40 megapixels, but my grouping algorithm averaged that sector out to 39), presumably this is a popular export size for illustrations, though not sure why.

Hello Bob,
nice analysis. I think the 39 MP result from people like Yuri who use a Hasselblad for a lot of their files, see here for example: http://us.fotolia.com/id/36352779
Ahh nice info, thanks 🙂
very interesting information, keep up the good work.
