1. Common uses of photo editing
1. Portrait beautification
◦ Skin smoothing: can make the skin of the person look smooth and delicate. For example, when the person's face has blemishes such as acne and freckles, the skin smoothing tool can be used to blur these imperfections to make the skin texture better. General image processing software such as Photoshop has filters such as "Gaussian blur" that can be used for skin smoothing. At the same time, some software provides intelligent skin smoothing functions that can automatically identify skin areas for processing.
◦ Whitening: adjust the skin color of the person to make people look more energetic. This can be achieved by changing the color balance of the image or using a special whitening tool. For example, in the mobile phone photo editing software, there is a one-click whitening function, which whitens the skin by increasing the brightness of the skin color part of the image and adjusting the color channel.
◦ Big eyes and thin face: change the facial contour and facial features of the person. Enlarge the eyes and reduce the facial contour through stretching, deformation and other operations. Some beauty camera apps can make eyes bigger and face thinner in real time when shooting. In the post-production Photoshop, you can also use the "Liquify" tool to manually make fine adjustments to the eyes, cheeks and other parts.
2. Landscape photo adjustment
◦ Color correction: Sometimes the landscape photos taken may have color deviations due to light, camera settings and other reasons. Photoshop can adjust parameters such as color balance, saturation, and color temperature to restore the true color of the scenery or create a unique color style. For example, a slightly gray seascape photo taken on a cloudy day can make the sky and sea look bluer by increasing the blue saturation and color temperature, creating a sunny feeling.
◦ Cropping and composition: Remove unnecessary parts of the photo by cropping to highlight the subject. For example, if there are messy branches or buildings around the mountain scenery photos that interfere with the subject, cropping can make the mountains more prominent. At the same time, you can also adjust the composition of the photo according to composition principles, such as the rule of thirds, to make the picture more balanced and attractive.
3. Creative synthesis
◦ Splicing pictures: Combine multiple different pictures together to create a new scene or concept. For example, stitching a photo of a person and a photo of the starry sky together makes people feel as if they are in the vast starry sky. In Photoshop, you can use layers and mask tools to achieve seamless stitching, and adjust the opacity of the layer and the gradient effect of the mask to make the stitching edge transition naturally.
Add elements: add text, patterns or other decorative elements to the picture. For example, add text information such as the date and location of the trip to a travel landscape photo, or add some small icons that match the theme, such as adding parasols, shells and other elements to a beach landscape photo, to make the photo more interesting and memorable.
