GIMP Layer Masks: The Non-Destructive Editing Habit Worth Building
Stop erasing pixels in GIMP. Layer masks hide parts of a layer reversibly using grayscale values — here's how they work, a two-exposure blend walkthrough, and the file-size and export trade-offs.
Content-Aware Fill: Default vs High Quality, GPU Trade-offs, and Layer Sampling
A technical breakdown of Content-Aware Fill's algorithmic paths, performance settings, and the 'Sample All Layers' compromise so you can fill selections faster and with fewer artifacts.
Non‑Destructive Editing in GIMP: Using Layer Masks for Selective Adjustments
Learn how GIMP’s layer masks let you tweak exposure, contrast, or color on just part of an image without altering the original pixels. Follow a step‑by‑step workflow, see the differences between GIMP 2.10 and 3.0, and avoid common pitfalls.
How GIMP’s Tile-Based Design and GEGL Let You Edit Massive, High‑Bit‑Depth Images on Limited RAM
Learn why GIMP can handle images larger than your memory, how to tune its tile cache, and what trade‑offs to expect when working with 16‑ or 32‑bit per channel projects.
gimpDiagnosing GIMP Slowness on Large Images: A Tile‑Memory & Swap Checklist
When GIMP gets sluggish on a 100 MP canvas, the culprit is often tile‑based memory or swap. This guide walks through a diagnostic flow, from checking undo history to tuning tile cache, and provides concrete fixes that keep performance smooth.
Designing Photoshop Layer Masks: Requirements, Minimal Architecture, and Failure Modes
Layer masks give Photoshop users per‑pixel alpha control without altering the underlying image. This note outlines the functional requirements, a minimal channel‑based design, data boundaries, operational checks, common failure scenarios, and when the design needs to evolve.
