4. View the effect and save the photo. (See Figure 5)

This method is very simple and practical, and it will look like an artistic photo after it is done. Readers can expand on this basis, adjust the opacity of the layer, or change the layer to other modes such as soft light, color filter, etc., which will also allow you to get different effects, and you can even combine multiple layers with Overlaying different transparency levels may yield unexpected results! The secrets are left to everyone to develop and think about!
