Step 4: Align Your Images

Photoshop will then work on aligning and stacking your images. This process might take a while if you're stacking many high-resolution photos. Once completed, you'll see all your photos listed as layers in the Layers panel.

Step 5: Blend Your Images

With all your layers selected (click the top layer, hold "Shift," then click the bottom layer to select them all), navigate to the "Edit" menu and select "Auto-Blend Layers."

In the "Auto-Blend Layers" box that pops up, select "Stack Images," and make sure "Seamless Tones and Colors" is checked, then click "OK."

Photoshop will now blend your stacked layers into a single image, keeping the sharpest parts from each photo.

Step 6: Finishing Up

You might notice some empty or uneven areas around the edges of your image due to the alignment process. Use the "Crop" tool to crop these areas out and finalize your image composition.

Finally, don't forget to save your work. Go to "File" > "Save As," and choose your preferred format.
