"Mode P and ISO" Mon 08-Mar-10 03:45 PM by riveredger
Question - if I want to manually adjust the ISO settings while in P mode, will the D3000 automatically adjust the shutter speed and aperture to match how I set the ISO? ie - if I drop the ISO from say - 800 to 400, will the camera automatically reduce the shutter speed?
I'm not good enough to go with M mode yet. But, I'm trying to shoot with lower ISO settings to reduce the amount of noise. Am I going about this all wrong, or does this seem like a reasonable approach?

Yes, while in "P" mode the camera will adjust aperture and shutter speed based the the ISO you have selected. Any automatic mode would do that, and in manual mode, changing the ISO will affect the meter.
Using the lowest ISO you can to reduce noise is a sound approach.
As a step towards using manual exposure, try Aperture Priority. This gives you control of the aperture, but allows the camera to select the correct exposure by choosing the shutter speed.

Yes though not always the shutter speed! In P, S, or A exposure modes when you change the ISO the Aperture or shutter speed will change to provide a correct exposure. In Program (P) mode, the Aperture or shutter speed may change depending on the ambient conditions. In Aperture (A) priority mode, the shutter speed will change. In Shutter (S) priority mode, the Aperture will change.

There is nothing wrong with your approach! The important thing is that you feel comfortable doing it that way. Depending on the ambient conditions you can also take advantage of using "Flexible Program" mode by rotating the Command dial while in program mode. You will see and Astrix after the P* in the display (see page 68 of your D3000 Users Manual). You could also try using Aperture priority mode and or Shutter priority mode when you feel more confident. Good Luck and Enjoy your Nikons!
M needn't even be a goal, although there's nothing wrong with that as a goal. I certainly have the skills to shoot in M, and in fact I do sometimes. Nonetheless, I find that A or S mode are just as good 90% of the time, and they require less intervention from me - so results tend to be better.
