Point of diminishing returns

Point of Diminishing Returns: The resolution threshold where increasing your camera’s megapixels no longer extracts new image detail, but instead just creates unnecessarily massive files. In 35mm film digitization, this sweet spot is typically reached between 24 and 40 megapixels. Beyond this window, you are no longer capturing sharper details of the actual photograph; you are simply recording the structural limits of the physical film grain and the optical limits of your macro lens.
