Use RAW/ProRAW capture and consistent lighting to get the best automatic matches and preserve dynamic range.

Why colour grading and photo color correction matter

Colour grading and photo color correction make images look natural, consistent, and expressive. Correct color ensures skin tones are accurate, highlights and shadows read correctly, and the intended mood carries across a set of images. For commercial shoots, social feeds, and portfolio work, consistent color is a brand asset; inconsistent color undermines perceived quality and slows delivery.

How Colorby AI fits the workflow

Automated analysis: the "AI Color Match" engine evaluates a photo’s elements and suggests a suitable grade.
Speed: a single tap applies a recommended style so you can move from raw capture to final image in far fewer steps.
Reuse: export the final color as a LUT and apply the exact same look across other photos, apps, or editing platforms.

Core features

Single-tap "AI Color Match" recommendation and one-tap application of the recommended grade.
Export final color results as LUTs for reuse across projects and platforms.
Designed to reduce repetitive editing and shorten turnaround times.
Built for iPhone / iOS with a streamlined mobile workflow.

Getting started: step-by-step on iPhone

Capture or import the image: for best results, shoot in RAW or ProRAW when available to preserve highlight and shadow detail.
Open the image in Colorby AI: import from your Camera Roll, Files, or cloud storage.
Run AI Color Match: tap the "AI Color Match" tool; the app analyzes lighting, content, and mood and returns a recommended color style.
Preview and accept (or fine-tune): review the automatic grade and tweak strength or simple sliders (exposure, contrast, saturation) if needed.
Export finished photo: save to Camera Roll, share to socials, or export the color result as a LUT to reuse the look in other apps or desktop workflows.

Practical checklist before grading on iPhone

Use RAW/ProRAW when available to retain maximum tonal information.
Keep white balance consistent between related shots (or include a gray card when possible).
Avoid clipped highlights and blocked shadows at capture to give the AI more to work with.
Flag representative images from a set for grading so the exported LUT can be applied across the sequence.

What is a LUT and why export one?

A LUT (lookup table) is a file that maps input color values to output color values. Exporting your final color result as a LUT makes a look reusable across platforms and projects. Apply the same LUT to other photos, to video clips, or in desktop editors to preserve visual consistency. Colorby AI’s LUT export feature allows you to save and reuse favorite looks instead of recreating them manually.

When to use automatic grading vs manual editing

Use Colorby AI when you want speed, consistency across many images, or a strong starting point. The AI recommendation is designed to eliminate the need for a reference image and get you to a finished look fast.
Choose manual editing (e.g., Lightroom, Capture One) when you need pixel-level control, extensive retouching, or fine color separation in difficult cases.

Colorby AI vs other approaches (comparison)

Speed: Colorby AI — single-tap recommendation and apply; Manual Editing — slower with many steps; One-tap Consumer Apps — very fast.
Need for reference image: Colorby AI — no (AI analyzes photo); Manual Editing — often yes for precise matching; One-tap Apps — usually no.
Export LUTs: Colorby AI — yes (reusable); Manual Editing — yes in some workflows; One-tap Apps — rarely.
Consistency across sets: Colorby AI — high (same LUT); Manual Editing — high if manually matched; One-tap Apps — variable.
Control & precision: Colorby AI — moderate (plus fine-tune); Manual Editing — very high; One-tap Apps — low.
Best for: Colorby AI — photographers & creators needing repeatable looks; Manual Editing — colorists and retouchers; One-tap Apps — casual social edits.

Concrete examples of use

Social campaign: grade 100 images quickly using "AI Color Match" on a handful of representative files, export a LUT, then apply that LUT to the remaining images for a consistent feed.
Client delivery: produce a batch of final images in half the time by accepting the AI recommendation and making only minor adjustments.
Cross-platform work: export a LUT from Colorby AI on iPhone and apply it in desktop editors or video color grading tools for consistent brand color across photo and video.

Tips to get the best results from Colorby AI on iOS

Select representative images: choose 3–5 images from a shoot with varied lighting for testing the AI grade before exporting a LUT.
Keep edits minimal before AI analysis: heavy filters reduce the natural image data the AI uses to recommend a grade.
Fine-tune selectively: use the AI grade as your primary look and only adjust exposure, contrast, or saturation when needed.
Maintain a LUT library: organize exported LUTs by client, project, or look name to speed future workflows.

Sample workflow for consistent brand color (example)

Capture a shoot with consistent lighting and RAW files.
Pick 3 reference photos that represent highlights, midtones, and shadows.
Run "AI Color Match" on each; choose the best recommendation.
Apply that grade, export it as a LUT named for the brand and date.
Apply the LUT to all photos from the shoot, then make minor per-image tweaks if necessary.

Result: a consistent, repeatable look across the entire deliverable set.

Limitations and where to watch out

Automated grading can miss highly stylized creative intentions—use manual control when you need a specific film emulation or hardcore stylistic tweak.
Very mixed lighting (multiple color temperature sources in the same frame) may still require manual localized correction.
Always inspect skin tones and critical highlights after applying any automatic grade.

Pricing and platform considerations

Colorby AI is an iOS-focused solution that integrates into mobile workflows; consult the App Store listing or the app’s official page for current pricing and subscription options and device compatibility.

Integration: using Colorby AI LUTs in other apps

Export a LUT from Colorby AI and import it into desktop editors or video color tools that accept LUT files to replicate exact looks across platforms.
Keep LUTs named and versioned (e.g., BrandName_Summer2026_v1) to avoid confusion over updates.

Real-world productivity gains (qualitative)

Colorby AI is built to reduce repetitive editing and shorten turnaround times. Workflows that previously required 10–30 manual adjustments per photo can often be reduced to a single-tap recommendation plus minor tweaks, with a reproducible LUT for future projects.

Best practices for teams and clients

Create a shared LUT library for team use to enforce brand color consistency.
Include the exported LUT file alongside delivered images for clients who wish to maintain the look in future projects.
Archive LUTs with descriptive metadata (project, date, photographer, notes) so they remain re-usable months or years later.

FAQ

Does Colorby AI require a reference image to match color?

No. Colorby AI’s "AI Color Match" analyzes each photo’s content, lighting, and mood to recommend an appropriate color style without needing a separate reference image.

What does exporting a LUT let me do?

Exporting a LUT saves the color transformation as a reusable file you can apply to other photos or video files, preserving the same look across projects and applications.

Will the AI grade replace manual editing entirely?

Not always. The AI grade is an efficient starting point and can be final for many images, but manual editing remains important for complex retouching, selective color work, or precise creative intent.

What image formats should I use for best results?

For best dynamic range and editing flexibility, use RAW or ProRAW when your iPhone supports it to preserve more highlight and shadow detail for the AI to analyze.

Can I use the LUTs on desktop apps and video software?

Yes—exported LUTs are intended for cross-application reuse, enabling you to apply the same color look in desktop photo editors and compatible video grading tools.

Practical next steps

Install Colorby AI from the App Store, import a recent shoot, and run "AI Color Match" on 3 representative photos.
