Tip 2: On Shutter Speed
Choosing the right shutter speed will be determined in large by your subject and the situation they’re in. The more active they are, the faster the shutter speed you’ll need. For example:
- If you have one subject (an adult or teen for example) who isn’t moving much or making big hand gestures, you can get away with using a 1/15th or 1/8th of a second shutter speed. Even in low-light this should be sufficient if your subject isn’t moving too much.
- If you have multiple (excitable) subjects, you’ll need to use something faster. A big group, or excited children, will require something around 1/125th and you can adjust from that point. If things are too blurry then go faster, but you may also need to adjust either the aperture or ISO as well.
Tip 3: On ISO
Your aim here is to get the best possible image quality when taking your portrait. This usually means having the lowest ISO possible, but this has to be balanced against shutter speed and aperture. Here’s our ISO advice
- To have the least amount of image noise, shoot at around ISO 100-400. This should be sufficient if the lighting is good.
- If you’re shooting inside, or in the shade, then increase this to around 800 to compensate. You can probably also get away with ISO 1600 as well, although be sure to keep an eye on image noise on your LCD.
Balance your ISO with aperture and shutter speed, being sure to get a balance that allows you to capture in focus shots that have minimal image noise.
