[QUOTE="WayneF, post: 215041, member: 12496"] Yes, low light normally considers a larger aperture, but more depth of field is a smaller aperture diameter, which is a larger f/stop number. It is confusing when you stop to think or talk, but it becomes second nature on the camera, thinking not necessary. :) OK, but you would try other alternatives than slower shutter speed if concerned with stopping motion. You get more ambient exposure with slower shutter speed, or larger aperture diameter (smaller number), or higher ISO, or possibly combining all of them. Or if ambient light is dim, you can use flash. The camera flashes are called speedlights because they are our best tool for stopping motion (in dim places). Their flash (at low power) can be extremely brief, to stop hummingbird wings, which simulates shutter speed if the ambient is dim (so ambient does not continue to blur it). Sensor noise is not a step function, it gradually increases. Where you say Ouch might be a step. :) Yes, if all things equal. [/QUOTE]
