How to get started in manual mode
1 Adjust the most important setting
For this shot we want to freeze movement, so we need a fast shutter speed. Use the control dial to set the shutter speed to 1/1000 sec. Start with the ISO set to 400, but change this if there isn’t enough light to get the correct exposure.
2 Use the exposure meter
Now you can change the aperture, until the indicator under the exposure metering bar is below the 0, rather than + or -. If you can’t get the indicator to zero, even at the maximum aperture, you should increase the ISO setting.
3 Fine-tune the exposure
Now take a test shot to check whether the exposure needs adjusting. On the LCD, check the histogram, and use a smaller aperture (or lower ISO) if the result is over-exposed, or a wider aperture (or higher ISO) if it’s under-exposed.
