How do you create a custom pattern in Photoshop?

I use the 'Focus Area' tool to create a selection based on depth of field, allowing for precise control over the focus area.

The 'Color Lookup' adjustment allows for remapping image colors to match a specific color palette or style, using 3D LUTs (Look Up Tables).

I use the 'Pattern Fill' feature and 'Pattern Editor' to create a custom pattern, defining the repeat and offset.

'Layer Group' is a logical grouping of layers, while 'Layer Set' is a physical grouping, allowing for nested groups and organization.

I use a combination of techniques like compositing, blending modes, and manipulation to create a surreal effect, often incorporating multiple images and layers.
