Composite Heat Pumps onto Residential Background

I have several standalone product shots of our new heat-pump models and I need them realistically composited into a single residential-style scene. The brief is simple: place each unit on the ground in a typical suburban backyard or side-yard so the image looks like a genuine installation photograph suitable for brochures and web banners.

I will supply
 – high-resolution PNGs of the heat-pump units with transparent backgrounds
 – a selection of RAW/JPEG residential backdrops, plus brand guidelines for colour tone and lighting.

What I need back
 – one flattened, print-ready TIFF (300 dpi, Adobe RGB)
 – one optimised web JPEG (max 2 MB, sRGB)
 – the layered PSD so we can adjust shadows or replace the unit later.

Key touches include consistent lighting, natural-looking shadows on grass or pavers, and subtle colour grading so the unit does not appear pasted in. If you normally use Photoshop, Lightroom or similar, that’s perfect; please keep the layers organised and non-destructive where possible.

Turnaround: 48 hours once I share the assets.
