Question...

Here\'s two shots... both are within a min. or so of each other... both are 1/30... both are ISO 100,

One shot is f/8... the Camaro, and the other shot is f/22... The shots are about 1 min. apart under the same conditions... same location

Shot in shutter priority... center focal point... spot metering...with a 30D and 300 f/4L IS...

Would shooting manual help this?... Would using a ND filter be of value?

well, the shutter speed seems to be fine, and you probably don\'t want to go lower than that. f/22 is not a great aperture for many reasons and you\'re maxxed out. So clearly, a 3 stop ND would be perfect for the lighting conditions to get the light level down and still be able to shoot 1/30s

Now, if you mean the metering was too bright and you just wanted to get a different exposure, the ND filter won\'t do anything about that. You\'d have the same result, just at a different shutter speed. To get the exposure right, use the histogram - meter the pavement or a wibal card (very useful toy), and set the thing manually.

Back in the day when it was super bright it was always a great day to pull a roll of Velvia and set the ISO to 40. After that it was just a saturation feast at low shutter speeds in the sun. Can\'t put an ND on the 14mm anyway
