Nov 2016 - Envato have anounced suspension of uploads to photodune. I'll post more on this when their plans become clearer.
Photodune.net is produced by Envato who have a strong track record in user sourced content sites, and a large database of creatives who buy digital products (web templates and themes, code, video, animations, vector graphics, 3d models etc) from the envato network of sites. At september 2015 envato quote a community of more than 5 million members and more than 9 million items for sale. (across the whole network).
Non-exclusive artists earn a 36% royalty.
Exclusive rates are very attractive, they are tiered - the more you sell the higher the percentage you earn from 50% up to 70% for sales of more than $75,000 p.a. ($3750 gets you from 50% to 51% and so on). Exclusive photographers are not-exclusive in the traditional sense (sole agency), but all the images they sell may be exclusive to photodune. Exclusives may sell other images elsewhere, this is similar to exclusive images at another agency but your entire photodune portfolio must be comprised of exclusive images.
Uploading is simple and painless, if your images are already keyworded then it's just a simple click to submit a group of images.
Prices for buyers: Either credits based or direct payment ($2 extra charge if not using prepaid credits)
Interestingly photodune specify uploading jpeg files as photoshop level 12 (if you do no already save them as level 12).
The past three years - to Sept 2016. have cemented photodunes' location into the lower middle tier of microstock sites, clearly the backing of a large database of buyers from their site network is paying a dividend. Things are looking very promising with some steady sales coming for me, photodune is slowly making it's way up the earnings table towards the top tier but faces stiff competition. Very impressive results for such a recent entry into the market (launch 2011).
