Techniques are provided for allowing a user to select a region within virtual imagery, such as a hologram, being presented in an HMD. The user could select the region by using their hands to form a closed loop such that from the perspective of the user, the closed loop corresponds to the region the user wishes to select. The user could select the region by using a prop, such as a picture frame. In response to the selection, the selected region could be presented using a different rendering technique than other regions of the virtual imagery. Various rendering techniques such as zooming, filtering, etc. could be applied to the selected region. The identification of the region by the user could also serve as a selection of an element in that portion of the virtual image.
