How to remove the grid.

Hello all. I am a first time user of Blender and wanted to ask a question. I want to make a video that has a guitar in it. I just want still images of it so I was wondering how to remove the grid surrounding the object so I can take a screen shot of it and use that. If there is way to export a single image, please tell me. Thanks
