Enhance and Render Images for Print

I have a set of images that need to be enhanced and rendered at high resolution for use in large-format print displays (expo banners / signage).

The source images are low quality, so I need a skilled freelancer who can:

Improve clarity, sharpness, and detail.

Enhance colours, lighting, and contrast for print impact.

Prepare final files at print-ready resolution (300 DPI or higher).

Deliver in suitable formats (TIFF, PSD, or PDF with bleed/CMYK profile).

Requirements:

Proven experience in image enhancement, rendering, or retouching for large print projects.

Ability to work with low-quality source material and upscale without losing detail.

Strong understanding of colour management for print (CMYK, profiles, proofing).

Quick turnaround with room for a round or two of revisions.

Deliverables:

Enhanced and rendered images suitable for large-format printing.

Final files delivered in high-resolution, print-ready formats.

Please include examples of previous work (especially for banners, posters, or expo displays).
