Glorious Canadian Fall: Help with ISO

[maple]

These were taken under situations of speed, the first on a speeding car and the other two from a helicopter. Evidently, all three shots leave much to be desired as far as sharpness is concerned.

How does one select the appropriate ISO? Quite frankly, how does one even change the ISO settings on the D10? In these situations, I doubt too that the flash would have been of any help. They were taken at about 5pm under a warm orange sun, with a 24-80 IS lens, under P mode without flash.

Help and advice solicited!

Few questions here that are simple to answer. My view: get out of the car/helicopter if you want to have a good shot. YOu need to spend time on composition and lighting, which you couldn't from those positions.

How to change the ISO: see your manual
Flash would help: no, to far, to wide

Look on your LCD or in your viewfinder, and check the shutter speed before you shoot. It's a bit of debate about how slow you can hold and keep a sharp picture. Some people can handhold down to 1/30 or 1/15. Others need to stay around 1/125. For really sharp photos you need 1/125 or faster, especially for scenics. Slower speeds work fine for "street" work. Take some pictures at different speeds and see what you get.

Rembember, if you're in a plane you not only have the forward movement of the plane to overcome for sharpness, but the vibrations as well.

As the previous posts said, you can check your manual for ISO adjustment. You can also use a fairly large appeture, f5.6 or 8.0 is plenty when you're that far away. You could even use a smaller appeture, but you might run into less sharpness from the lens.

If you're not in an aircraft but on the ground, you could use a tripod with much slower shutter speeds.

The colors look beautiful. Keep looking for a sharp shot.
