Frequently Asked Questions

What are the most useful image filters and when should I apply each one?

Each filter serves a specific purpose: (1) Grayscale — converts to black and white, useful for print-ready documents, artistic effect, or reducing visual distraction. (2) Sepia — adds a warm brown vintage tone, great for historical or nostalgic aesthetics. (3) Brightness & Contrast — the most fundamental adjustment; increase contrast to make images pop, adjust brightness to correct exposure issues. (4) Saturation — increase for vivid, eye-catching social media images; decrease (toward grayscale) for a muted, professional look. (5) Blur — use Gaussian blur for background softening (bokeh effect), privacy redaction (blur faces or sensitive text), or creating depth-of-field effects. (6) Hue Rotation — shift all colors around the color wheel for creative color grading. For best results, apply filters in this order: brightness/contrast → saturation → hue → blur.
