How does Canon SX 100is shoot a good portrait?

This thing can't be explained clearly in a few words, so we should pay attention to the following points:

Be familiar with your camera. When shooting outdoors, the light changes and the model's action expression changes quickly. Need to be familiar with the performance of our camera and the conversion of various modes, such as aperture, ISO adjustment, exposure locking, etc. In order to grasp the decisive moment.

2, ready to fill the light board, external flash. In summer, the outdoor light is stronger, and the face is darker when shot in backlight. At this time, the fill light board and flash will be of great use, which can fill the face in time and avoid the exposure of black face and background. It is best to use an external flash, because the synchronization speed of the internal flash of the camera is low, which will automatically reduce the shutter speed when used, which often leads to overexposure of the background or face. External flash has higher synchronization speed, which is common in TTL (automatic and accurate determination of flash intensity through lens photometry), and can accurately fill the light.

3. Use spot metering and aperture priority mode to flexibly adjust ISO and aperture. Outdoor light often changes. It was sunny just now, a cloud will make the sky overcast, and the evaluation of photometry will be very inaccurate. Using spot metering mode to measure the spot surface can get relatively accurate exposure. When shooting in backlight, if you don't want to overexpose the background, if there is no light compensation board, you can measure the background, then lock the exposure with the exposure lock key, refocus the composition, and fill the face with a flash. Blurred human imaging is also a common problem. In addition to accurate focusing, we must maintain a certain shutter speed to prevent hand shaking. In aperture priority mode, you can blur the background with a large aperture to improve the shutter speed, which is a good choice without a tripod. At the same time, in the case of no obvious increase in noise, improving ISO is also a good way to improve shutter speed.

4. Change the angle. The outdoor space is relatively open, which provides many possibilities in composition. Up and down, forward and backward pitching, changing angles, often have unexpected gains.

5. Strengthen communication with models. We are mostly faced with amateur models, and their postures and expressions are not in place. Strengthening communication and telling her how to adjust her desired posture, expression or feeling will often get good results.
