Agefotostock is a stock photography "agency" like many others online, the most famous being Getty image, Corbis, istock or Shutterstock.
Of course not a lot of people (and customers) have ever heard about Agefotostock while they have been there for longer than any other provider. They are known by a small number of photographers and some editors I suppose.
If yoy are a photographer and want to sell pictures with them, don't bother to go through their super lengthy and complicated upload and selection process (done by hand), you will only lose time as they won't sell any of your work.
They are poor at selling your work but very good at adding one administrative barrier after the other in term of signing a contract with them.
You need to download and sign a contract that you need to print and send by post to Barcelona in Spain (at your own cost of course).
The contract with clauses favouring only them and registered under Spanish laws binds you for no more than 3 YEARS!
If you want to cancel the contract... Too bad, you have to wait and write 90 days before the expiration (by post again) to cancel it, otherwise it renew itself automatically.
For information all other stock agencies have electronic and online contracts, don't bind you for longer than 6 months and you can cancel anytime.
Why is it different at Agefotostock? Besides an obvious outdated and archaic culture that you can see when visiting their website it is in fact a well calculated strategy to dispossess photographers from their work and deter them to leave this provider.
You realise it, when after having sold nothing, you want to remove some pictures of your online portfolio with them to sell them elsewhere.
While with any other provider, you can do it easily and by yourself, with Agefotostock you simply can't.
And when you ask the pitiful customer service if they can remove pictures of your choice from your portfolio, first they don't answer for weeks and then come back to you in a very disagreeable and nasty way with reference to the contract you signed and with a big no in your face.
Basically, because you have signed this contract, your can't do what you want with your pictures anymore.
It explains why such a complicated way of contracting with them and why they are the only ones still using hard copy and paper. To trick the photographers into a trap where they are stuck for 3 years at least and more as most contributors won't bother to send a cancellation letter by post to Spain.
If you are a buyer, the usual practices of this nice agency consist amongst others to sell pictures without model or property releases (exposing the customer to possible copyright violation and subsequent trial and loss of money).
I have also heard of photographers who found their picture on sale on their website while they never signed with them. Again, a good source of troubles for any would be buyer in term of future suing.
As a photographer you should also be careful about what they do with your work online and make sure to check regularly on image research sites (google) to see if they don't distribute your images without telling you.
They pretend they are there since a long time and still most of people have never heard about them even in the (small) photography world. There are certainly good reasons why. Good product, good companies and quality don't stay hidden for long.
