If something looks off

AI changed the wrong area or blue hour effect too subtle

Why: The AI may have applied a gentler version than expected. Blue hour is a specific color palette.

Try: Be more emphatic: 'apply strong blue hour filter with very deep blue sky and vivid warm lights'

Try This →

Tip: Blue hour has distinct characteristics. Describe them: 'deep blue sky' + 'warm orange lights' for better results.

Sky turned blue but lights didn't warm up

Why: The AI focused on sky color but didn't enhance artificial light sources.

Try: Explicitly request both: 'apply blue hour with deep blue sky AND enhance warm glow from all light sources'

Try This →

Whole image looks too blue, lost warmth

Why: Overly aggressive blue application without preserving warm tones. Blue hour needs color contrast.

Try: Try: 'blue hour filter with blue sky but preserve warm tones in lights and highlights'

Try This →

Effect looks unnatural or oversaturated

Why: Blue hour can look artificial if too saturated. Fine line between dramatic and fake.

Try: Request subtlety: 'natural blue hour filter with realistic twilight colors, not oversaturated'

Try This →

No change visible or very minimal effect

Why: Photo may already have blue hour qualities, or AI didn't recognize the request.

Try: Be specific: 'transform sky to deep indigo blue twilight and make all lights warm orange-gold'

Quick answers

Do I need to mark anything before applying blue hour?

No! Just describe the effect: 'apply blue hour filter' or 'add twilight blue hour atmosphere.' The AI recognizes skies, light sources, and applies the characteristic blue hour colors automatically. No marking needed.

How do I add blue hour filter to a photo for free?

Upload your outdoor image to EditThisPic and request blue hour: 'apply blue hour filter with deep blue sky and warm lights.' The AI transforms the sky to deep twilight blue and enhances warm tones in artificial lights. Free to use, no account needed.

What is blue hour in photography?

Blue hour is the twilight period just after sunset or before sunrise when the sky turns deep blue while artificial lights appear warm orange. It creates magical contrast between cool blue ambient light and warm artificial lights. Photographers prize this brief window for its unique atmosphere.

Will this work on any photo or just cityscapes?

Best on outdoor scenes with visible sky—cityscapes, landscapes, architecture, streets. Works great with artificial lights (buildings, street lamps) for classic contrast, but also enhances nature scenes with rich twilight blue tones. Indoor photos won't benefit much.

What's the difference between blue hour and just making the sky blue?

True blue hour is a specific color palette: deep indigo-blue sky + warm orange lights + soft atmospheric glow. It's not just blue sky—it's the interplay of cool and warm tones. The AI creates this entire look, not just color-shifts the sky.
