1. A method for generating an image for a scene from a first image of the scene and a second image of the scene, the first image having a first exposure value, the second image having a second exposure value smaller than the first exposure value, comprising: generating, at a third exposure value intermediate between the first and second exposure values, a third image from at least the first and second images; analyzing the third image for adequacy of exposure; and generating a fourth image for a fourth exposure value intermediate between the first and second exposure values from at least the first and second images, wherein either: said generating the fourth image follows a result from said analyzing; or a choice for an adequately exposed image is made between at least the third image and the fourth image after said analyzing.
