[QUOTE="Essence of Imagery, post: 5967, member: 920"] Here are the [U][B]GENERAL[/B][/U] rules of thumb. 1. ISO - usually used for adjusting how much light you have surrounding you - the brighter the light, the lower the ISO, the darker, the higher the ISO. The main exception I shoot is long-exposure night photography - if shutter speed doesn't matter, don't sacrifice image quality. Higher ISO numbers equal increased "noise" in your images. Low ISO: [IMG]http://www.essenceofimagery.com/nikonites/low-iso-example.jpg[/IMG] vs. high ISO: [IMG]http://www.essenceofimagery.com/nikonites/high-iso-example.jpg[/IMG] See inset for close-up 2. Aperture - usually used for adjusting depth of field (sometimes called depth of focus). If you want a background blurred out, use a smaller number (shorter DOF), if you want everything in focus, use a larger number (longer DOF). Wide Open Aperture: (f/1.8) [IMG]http://www.essenceofimagery.com/nikonites/small-dof-example.jpg[/IMG] Stopped down Aperture: (f/8) [IMG]http://www.essenceofimagery.com/nikonites/large-dof-example.jpg[/IMG] 3. Shutter Speed - In general, used to stop motion. The faster your shutter speed, the more you stop motion - in some instances that's a good thing, sometimes not so good. Slower shutter speed: (1/80th) [IMG]http://www.essenceofimagery.com/nikonites/slow-shutter-speed-example.jpg[/IMG] vs. Fast shutter speed: (1/1600th) [IMG]http://www.essenceofimagery.com/nikonites/fast-shutter-speed-example.jpg[/IMG] Vehicles were going approximately the same speed, look at the wheels for the best indicator of shutter speed.
