Recommended Settings.
ISO:- Keep it on 100 unless light levels drop, then use ISO 200.
Exposure mode:- Aperture Priority mode will assist to control depth of field.
White balance:- Keep it on auto.
Drive mode:- Choose continuous to catch the atmosphere of the moment.
Metering mode:- Choose multi-segment (matrix/evaluative), switch to Spot metering from your model's face if backlit or if the lighting is mixed.
Focus points:- Use single point and focus on the models eyes.
Autofocus mode:- Choose single shot, so that every frame is crystal clear and sharp.
Light.
To achieve a flattering condition for portraits use soft diffused lighting. Try to avoid shooting under the midday sun on a bright day, as this will cast deep shadows directly onto the model. Place your model in the shade or the shadow of a tree to soften the light. Use a reflector to divert light directly on to the models face, or use small bursts of light from your pop up flash or a separate flashgun.
Simple is best.
The model needs to be the obvious centre of attention. A messy background will distract the eyes from focusing on the model. It is crucial to get the eyes in focus. So by selecting a centre AF point of view, you will need to use a AF lock or select a different AF point manually. By using a shallow depth of field, this will assist your model to stand out and be more sharp. Use a large aperture (meaning a low f-number) narrow depth of field. This will help eliminate camera shake by giving you a fast shutter speed.
The correct pose
Try to create a dynamic pose by getting the model to bend her knees or by directing her legs at an angle to the camera to give a better shape to your composition. The facial features convey the models character and mood.
