Compositing two photographs together in Photoshop no longer requires tedious manual masking or painstaking color matching. By leveraging modern contextual tools and AI features, creators can execute flawless image blends in just a few clicks. 

The workflow begins by dragging a target subject directly onto the background document tab.

Holding the Shift key before releasing drops the new layer precisely into the center of the canvas. 

From there, opening the Contextual Taskbar allows photographers to click "Remove Background," instantly isolating the subject on a clean layer mask.

Sizing, Positioning, and Transform Controls

Once isolated, enable "Auto-Select" and "Show Transform Controls" within the Move Tool options bar to scale and reposition the subject dynamically. 

Dragging corner handles lets you quickly dial in realistic proportions before committing the final transform placement.

One-Click Lighting and Color Harmonization

To eliminate the harsh "sticker look" caused by mismatched color temperatures and lighting angles, simply click the "Harmonize" feature. Photoshop analyzes both layers to adjust ambient illumination, automatically generating natural grounding shadows and environment reflections. 

Creators can select from multiple variation presets in the Properties panel to choose the most convincing match.

Practical Studio Advice: When dragging a subject into a new background image, always hold down the Shift key before releasing your mouse button to ensure the layer aligns perfectly in the center. Use the "Harmonize" button in the properties panel to match tone, lighting, and reflections instantly, then browse the generated variations to select the best match for your composition.
