In order to put the model at ease, bring some music with you! Firstly, this will guarantee some great candid shots and, furthermore, the situation is much more relaxed. Plus, if you're going for a certain mood in your photos you can choose the music accordingly! This is also great for people who aren't used to modelling.
Talk to the model while you're shooting and tell him or her what you're doing. If you don't tell the model that you're - for example - adjusting your settings, he or she will think that it's them who aren't posing quite right. This will show in your photos, so avoid that by communicating.
