Cách sử dụng công cụ Double Exposure trong Snapseed

Tạo hiệu ứng phơi sáng kép đẹp mắt trong Snapseed là một quá trình gồm hai phần. Đầu tiên, bạn phải chuyển hình ảnh bóng đen trên nền trắng, được hỗ trợ bởi các blending mode khi hiển thị hình ảnh thứ hai. Trước khi bắt đầu, bạn có thể tải xuống ứng dụng Snapseed miễn phí.

Đây là cách tạo hình ảnh bóng đen trên nền trắng:

Step 1. Open Snapseed and import your image.

Step 2. Go to Tools > Black and White and choose Color Filter to make your background light.

Step 3. Adjust Brightness and Contrast to get a black shadow on a white background. Keep Contrast at 100 for best results.

Step 4. Click the checkmark to save your edit.

Step 5. Go to Tools > Curves and select the RGB color channel.

Step 6. Bring the right cursor all the way down to make your image completely black and save it by touching the check mark.

Step 7. Open the Edit Stack > View edits option, click on Curves and open the Slack Brush.

Step 8. Erase any white spots on the object using the Brush.

You have completed the first step of creating a double exposure image. Make sure the shape you want to keep is black and the part you don't want is white (usually the background). You will understand what it means when working with Blending modes.

Here's how to use the Double Exposure feature:

Step 1. After finishing editing to a black shadow on a white background, go to Tools > Double Exposure.

Step 2. Click the Open Image option to add a second image.

Step 3. Position the second image as you want and choose the Lighten blending mode from the Style options. The image will only display in the dark area.

Step 4. Add another image and set the Blending mode to Darken or Subtract. It will add the image on the white part.

Step 5. Go to Stack Options, open View edits, click on the closest Double Exposure edit and select the Slack Brush. Use it to remove unnecessary parts from the image.

Step 6. Refine your image with some final tweaks, adding effects and filters if required before exporting the final edited result.

You already have your double exposure and can experiment with it a lot more however you like. You can add objects to another image or create something similar to a movie poster. TipsMake also has a tutorial for creating a double exposure effect in Photoshop .

Two important steps while using the Double Exposure function is to use the Blending modes properly and use the Slack Brush to mask the less important areas. Slack Brush is similar to using layers and masks in Photoshop.
