Fine-tune adjustments: Apply additional adjustments to the overlay layer, such as color corrections or filters, to harmonize it with your image.You can also use layer masks to selectively hide or reveal parts of the overlay. Opacity and masking: If needed, lower the opacity of the overlay layer to make it more subtle and blend it with the underlying image.Experiment with different blending modes such as Overlay, Screen, Multiply, or Soft Light to see which works best for your image. Blend the overlay: In the Layers panel, adjust the blending mode of the overlay layer to achieve the desired effect.You can hold down the Shift key while resizing to maintain the aspect ratio. Adjust the size and position: Use the transform tools (Edit > Free Transform) to resize, rotate, or reposition the overlay as desired.The overlay will appear as a new layer above your image. Import the overlay: Go to “File” > “Place Embedded” or “Place Linked” and select the photo overlay file you want to use.Open Photoshop: Launch Photoshop and open the image you want to work with by going to “File” > “Open” and selecting the image file.
