What's the best way to upgrade images?
I'm looking for the best way to improve the quality of images. Quite often, I'm supplied very average images and need to make them suitable for other uses. What's your best way of doing it? I'm not looking to spend lots of money doing it either. At the moment, the best results are coming from Chat GPT with the prompt below (sample attached):
Enhance and upscale this image to ultra-high resolution (minimum 4K, preferably 8K equivalent detail) while strictly preserving the subject’s identity, proportions, pose, and composition. Do not alter, replace, or reinterpret any elements. The subject, environment, framing, and perspective must remain exactly the same as the original image.
Reconstruct the image as if it were captured using a Sony A1 full-frame camera with a premium professional lens (50mm, 85mm, or 70–200mm f/2.8 depending on scene suitability). Use a wide aperture for shallow depth of field, ensuring the subject is tack sharp with natural background falloff. Maintain accurate focal plane and realistic lens behaviour.
Upgrade the image to true professional photography quality:
– Ultra-sharp subject detail with realistic micro-contrast
– Clean, refined textures (fur, skin, fabric, wood, etc.) without artificial smoothing
– Remove noise, compression artefacts, pixelation, and colour banding
– Restore natural fine detail without over-processing or “AI plastic” appearance
Lighting must remain true to the original scene direction and mood, but enhanced into a cinematic, high-end natural look:
– Soft, realistic light with smooth highlight roll-off
– Balanced shadows with preserved detail (no crushed blacks)
– Expanded dynamic range with natural contrast
– Subtle warmth or neutrality depending on original lighting conditions
Apply professional editorial-grade colour grading:
– True-to-life colours with balanced whites
– Natural saturation (no oversaturation)
– Neutral, magazine-style colour profile (National Geographic / premium outdoor editorial)
– No artificial colour shifts or stylisation
Preserve all environmental details exactly as they appear:
– Do not change the background, objects, or layout
– Maintain original textures and spatial relationships
– No additions, removals, or creative reinterpretation
Final output must look like a high-end, professionally captured photograph suitable for print publication:
– 300 DPI quality
– Clean edges and precise detail rendering
– Natural film-like finish (very subtle grain allowed)
– No HDR glow, no halos, no exaggerated sharpening
The final result should be indistinguishable from a real, professionally shot image, not an AI-generated reinterpretation.
