The defaults look decent, but you want more — a finer pencil texture, bolder sketch strokes, or that precise Japanese animation genga line quality. Faced with a row of parameter sliders, you don't know which to adjust or by how much.
This guide breaks down every Louvre Generator style parameter to the atomic level: what each one does, recommended ranges, and optimal combinations for different subjects (portraits, landscapes, still life). After reading, you'll be able to precisely "tune" your own signature line art style.
01 Line Weight: Defining Visual Character
Line weight is the parameter that defines the "first impression" of your sketch. Thick lines feel like charcoal pressing hard against paper — powerful, tense, suited for street photography, architecture, and male portraits. Fine lines are delicate as spider silk — perfect for florals, female portraits, and soft aesthetics.
Medium weight is the safest choice but the least distinctive. Truly memorable line art gravitates toward extremes — either bold minimal strokes or intricate fine lines composing a ukiyo-e-like composition.
- Ultra-fine (1–20%): refined and literary — florals, female portraits
- Fine (20–40%): clean and elegant — closest to One Last Kiss aesthetic
- Medium (40–60%): universal and safe — works for most subjects
- Bold (60–80%): powerful — architecture and male portraits
- Extra-bold (80–100%): expressionist — posters and abstract art
02 Detail Retention: Between Information and Space
Detail retention determines how much of the original image information is converted into lines. High retention traces every leaf vein, every fabric fold; low retention preserves only core contours and shapes.
Negative space is the soul of line art. Japanese animation masters understand this instinctively — those breathtaking sketch frames feature vast empty space, with only a few strokes outlining essential contours. For this aesthetic, set detail retention to 30%–50%.
But if your goal is a frame-worthy detailed sketch, push detail to maximum — 80%–100% retention produces incredibly rich line layering, as captivating as a master's hand-drawn study.
03 Combining Contrast with Stroke Style
Contrast and stroke style are "pair" parameters — together they define the sketch's emotional tone. High contrast + hard stroke = woodcut-like visual impact; low contrast + soft stroke = the gentle texture of pencil on paper.
Contrast determines how sharply "line" separates from "space." High contrast yields decisive, unambiguous marks; low contrast introduces gradients, fading edges — like viewing art through mist.
Stroke style simulates different drawing tools — pencil's fine grain, pen's crisp precision, charcoal's raw abandon. Your choice depends on what drawing scene you want viewers to imagine.
Want the signature One Last Kiss look? Set: fine lines + 50% detail + high contrast + pen stroke. That's the clean, purposeful, one-stroke-captures-the-soul animation genga feel.
04 Parameter Quick Reference by Subject

- Landscapes: line 20%, detail 50%, contrast 50%, stroke Pencil
- Architecture: line 50%, detail 80%, contrast 85%, stroke Pen
- Floral/Still life: line 15%, detail 55%, contrast 60%, stroke Pencil
- Street photography: line 60%, detail 45%, contrast 90%, stroke Charcoal
FAQ
Is there real-time preview while adjusting?
Yes, the line art preview updates in real time after each parameter change, so you can visually track the effect of every adjustment.
Can I save my parameter presets?
We recommend screenshotting or noting your preferred parameter values. Once you find your style, these values can be quickly reapplied to different images.
What if I over-adjust the parameters?
Reset to defaults and start over at any time — the original image is never affected. Don't hesitate to try extreme settings; sometimes the best results come from experimental combinations.
What are different line art styles best used for?
Minimal outlines suit avatars and logos; One Last Kiss style is perfect for social sharing and print décor; fine sketches work as portrait gifts and art collections; quick sketch style fits creative journals and planners.
Can I export multiple versions with different settings?
Yes. Adjust and export, then adjust again and export another — no re-upload needed. You can easily create multiple stylistic versions of the same photo.
