A computer-implemented method of modifying images of an environment for storage or transmission comprises receiving (204; 404; 604, 608) user input defining at least one selected feature of, or within, an environment. An image of a portion of the environment is captured (212; 410; 614) using an image capture device. The method can identify (216; 414; 618, 622) at least one object and/or at least one area in the image based on the at least one selected feature, and modify (218; 416; 624) the image to include or exclude the at least one identified object and/or the at least one identified area. The modified image can be stored or transmitted (220; 418, 420; 626, 628).
