系列简介

本系列是一套专为 Krea 2 设计的轻量级图像属性控制滑块 LoRA 模型。可独立调整生成图像的对比度、亮度、饱和度三项基本视觉属性。每个 LoRA 对应一个方向明确的连续控制维度，您只需在生成时调节 LoRA 权重（正/负值）即可实现从“极低”到“极高”的无缝渐变，为图像后期微调提供精准、高效的工具。

各模型功能简述

对比度控制滑块：调整画面明暗反差强度。正向权重增强阴影与高光之间的对比，使画面更具冲击力；负向权重减弱反差，使过渡更柔和、层次更平缓。

亮度控制滑块：调节画面整体明暗水平。正向权重提升画面亮度，使图像更通透、明亮；负向权重降低亮度，营造昏暗、沉静的视觉效果。

饱和度控制滑块：控制画面色彩的鲜艳程度。正向权重提高色彩浓度，让画面更生动艳丽；负向权重降低饱和度，色彩趋于灰白，适用于做旧或简约风格。

Series Introduction

This series is a set of lightweight image attribute control slider LoRA models designed specifically for Krea 2. It allows independent adjustment of three fundamental visual attributes in generated images: contrast, brightness, and saturation. Each LoRA corresponds to a clearly defined continuous control dimension. Simply adjust the LoRA weight (positive/negative values) during generation to achieve seamless gradation from "extremely low" to "extremely high," providing a precise and efficient tool for fine-tuning images in post-processing.

Model Function Overview

Contrast Control Slider – Adjusts the intensity of light–dark contrast in the image. Positive weights enhance the contrast between shadows and highlights, giving the image more impact; negative weights reduce contrast, resulting in softer transitions and flatter tonal gradation.

Brightness Control Slider – Adjusts the overall lightness level of the image. Positive weights increase brightness, making the image more transparent and luminous; negative weights decrease brightness, creating a dimmer, more subdued visual effect.

Saturation Control Slider – Controls the vividness of colors in the image. Positive weights boost color intensity, making the image more vibrant and striking; negative weights lower saturation, shifting colors toward grayish tones—ideal for vintage or minimalist styles.
