Sectora is an intuitive, grid-based utility that helps artists transfer, analyze and refine images with greater accuracy and less guesswork. The app overlays a customizable grid and optional diagonal guides so you can break complex compositions into manageable sections, check proportions, and study values and color relationships. Whether you work in portraiture, landscape, still life or mixed media, Sectora streamlines composition work with mosaic and blur analysis modes and a clean, user-focused interface that keeps tools accessible while you concentrate on drawing, painting or digital rendering.

Key Features

⭐ Sectora's Customizable Grid System — change the number of sections to suit sketches, paintings or digital compositions for precise proportion transfer.

⭐ Diagonal Guidelines — optional diagonal lines help refine perspective and strengthen compositional anchors.

⭐ Mosaic Effect — reduce an image to color blocks to reveal dominant hues and simplified value structure for clearer color analysis.

⭐ Blur Effect — soften fine detail to isolate primary shapes and tonal relationships, useful for value studies and initial blocking-in.

⭐ Advanced Visual Tools — dynamic grids and visual overlays simplify complex scenes, making it easier to plan and execute artwork.

Advantages

✅ Improves proportional accuracy, making it easier to transfer reference images to canvas or paper.

✅ Simplifies color and value analysis so you can identify dominant tones and subtle transitions faster.

✅ Speeds up the planning stage of a piece by breaking compositions into clear, manageable sections.

✅ Sectora’s clean, user-friendly interface keeps useful tools accessible without interrupting the creative flow.

Disadvantages

❎ Focused primarily on sectioning and visual analysis rather than providing a full-featured image-editing or painting studio.

❎ Analysis and guides often need manual follow-through on a physical canvas or a dedicated art program to complete the final rendering.
