I'm posting this in the "pro" section since this is about selling photos, but I'm only an amateur enthusiast. I hope this is the right place to ask this question...
The company I work for publishes a yearly calendar for our distributors around the world. My wife, who is a brand manager at the same company, recommended that I submit some of my photos for our 2014 calendar. I've never sold a photo in my life, so I really have nothing to measure this against. I really don't know where to start, how much to charge for each photo. I found out today that this year's photos were provided by another employee's father and he was paid 800€, or roughly $1040 USD, for 12 photos.
I should add that we are not talking a huge number of calendars... probably a few hundred at best, maybe 500 at most. There would be one photo per month, so 12 photos in all. I am able to supply all 12 photos. All have been shot on my K-5 with various lenses I own. I have the original raw files and will provide processed JPEG's as a deliverable. I will also request copyright marking of each photo, either burned in during export or text printed below the photo.
Is 800€ a good price for 12 photos? It's not exclusive and the photos would be licensed only for use in this calendar for one run. I have already created a book in Lightroom with candidate images and exported it as a PDF, 4 photos to a page. I don't really need to "sell" this idea at this point, it's really down to letting our graphic designer select the photos she wants to put into the calendar and of course agreeing on terms and price before I deliver the final full-res images.
Of course, I am already planning to buy my first DA Limited(s) in the near future depending on how much I make from the sale...
