You can use Photoshop's Generative Fill to merge two photos with just a few clicks.
In this document I have two photos with similar lighting.
The couple canoeing photo will be much better if we had the top of the tree line and some sky.
So I found a photo that has similar lighting and the bright sun on the right side like we see on the reflection in the water.
To merge these layers all you need to do is enable the Rectangular Marquee Tool and make a selection that includes the transparent pixels between these images as well as part of the sky and trees to give Photoshop room and context to generate the blend.
Now click on the Generative Fill button and leave the prompt blank.
Then click Generate.
Photoshop will generate content that blends these two images in a very realistic way, and you can click on this icon to look at the other variations which also look fantastic.
Now try merging your photos using their Generative Fill in Photoshop.

Thank you so much for watching.
