Three have been bought, and one is being used for a project already.
Well, I suppose since it's your husbands company...but you should know that without your written permission, the use of that photo is a copyright violation. Something to consider, you may not feel like a professional, but when you sell your photos...you are a professional and you need to treat your work that way. That said, in your circumstances...I think you'll be fine, but many companies will start infringing on your work and you are limited in damages if you do not register your images. FWIW
, if your husbands company is looking for photos, feel free to have them browse www.reefrunner.us/gallery/
and contact me (email contact is on the index page www.reefrunner.us
) if there is anything they would like to purchase
