看書學來的。透過自身影像模糊化的黑白副本來製作 layermask。Photoshop裡的程序大概是這樣:
1. Open the images in Photoshop.
2. Copy and paste the short exposure on top of the long exposure in a layer.
3. Create a layer mask.
4. Paste the long exposure into the mask.
5. Open a new view of the image to see effects of manipulating the mask.
6. Blur the mask.
7. Adjust the density and contrast of the mask with curves.
8. Tweak the color of the core to match the rest of the image.
9. Flatten the image to combine the layers and save the file.
謝謝細心回覆~
