There are methods to make models comfortable. Some are already ready to act the part, while others need some handholding. In advance of the photo shoot, I provide models the story lines (or script) I want them to narrate. This is crucial, since with it in mind, they can act the role. The other method is to encourage them as they pose...not so much as how or where they are to stand, but reminding them of adopting certain poses following the script as in "show me how Meili wishes she had never met the gweilo"...or "show me how Hua is scared of seeing her aging lover...".
I don’t do a lot of big stock photography, but I do stock images with TandemStock and they have done quite well for me. I haven’t been stocking with them for long, but I do leave a lot of my adventure and outdoors style photos in their hands. I earn about $150 a month with them for now, which doesn’t sound like a lot. However, they have made some high-profiles sales for me. For example, I was the background for Bing. I love TandemStock, and I hope they start to grow a bit.
Tip from a pro: Instead of trying to work with a large media organization like a magazine or newspaper, become a small media icon yourself. If you have a large and influential presence on social media, such as Facebook and Twitter, you might be more appealing to these organizations than old school media. So, start a blog, gain followers, and who knows, you could be their next photographer.
Make use of people to give your images life and scale. If the facade of a particular building appeals to you, the picture may be that much better if you show people walking in front of it. They will give it scale and also let viewers know what sorts of people live there, how they dress, and the like. An outdoor café may be more interesting crowded with people than empty.
