I sell stock images ,it can be ok supplemental income, but it can be slow getting started. I recently submitted some images to Cavan (Getty images) for review they take three weeks to get back to you . They pay more money than other stock image companies but they unlike other companies want to own the copy right to your images. Shutter point works well as do a few other outlets. If you are going to be traveling then selling stock images would fit into that well, manage to take plenty of images just making sure to take a camera with me every where I go. I never leave the house without one.

What I am saying is that you can make as little as a few cents per each use of your photo which is the most common way way you make money to several dollar depending on the image is purchased. A lot of these companies have different ways of doing business, the better ones allow you to keep 80% of the sale of your work every time stock is purchased. But that does not mean you are getting rich every time someone buys one of your images for use in a presentation , a report or what ever they are doing. You can also make several dollars, it all depends on what type of photo it is. If you are where the action is and there is lots of news worthy events going on the news worthy stock imagery is worth more than my landscapes of Oklahoma , Texas and where ever else I am traveling to at the time.

One of the reasons I am currently talking to Cavan Images right now is that they pay a lot more for every image they buy from you. A person if they sell a lot of images to them could make a tidy some , but when you sell to Cavan you are also agreeing to sell your copy right to the image, they do allow a fine art use of the image by you and they allow you to use the image in your portfolio. But you cant sell the images on your own like you can with the other stock image companies. With companies like shutter stock you retain your copyright. I actually sell a lot of my stock images independently of stock agencies in addition to using shutter stock.

Depending on how much you shoot and submit you can potentially make anywhere from an extra few hundred to several thousand dollars a year from stock photography. I know of no one that earns a living shooting stock photos exclusively. That would be hard living IMO you would be busy all day long shooting images of pretty much a lot of things. Some stock agencies issue assignments with criteria and those pay more money because there is a specific client wanting a specific photograph and some agencies actually charge you to use their services.

I hope all of that answers your questions.

Well, more = better.

The consideration is to support a family of 3 (one more on the way soon) by doing jobs available while traveling. So we wouldn't be relying on stock video/photos for a primary source of income, but any extra boost would help... plus there is a potential to have it continue to generate revenue down the road with little/no additional effort.

Right now we do graphic design, photo and video capture and editing. Seriously considering getting a steadicam and using the next year or so of travel to practice with.
