Banding occurs when subtle color shifts are lost, creating unnatural steps in tone.

It commonly occurs in digital images, videos, and on displays when there isn't enough color depth to render subtle transitions.

This issue is especially noticeable in skies, sunsets, or any large area with gradual color changes.

To resolve banding, you must identify whether it stems from hardware, software, or file quality.

Verify the source by opening the file on multiple devices to isolate the origin.

Try viewing the file in alternative software like DaVinci Resolve, GIMP, or VLC.

This indicates your display may lack proper color depth or calibration.

Low-cost screens frequently employ temporal dithering to stretch limited color gamuts, causing noticeable banding.

High quality monitors with 10 bit panels handle gradients much better.

Color depth settings can often be overlooked but are critical for gradient fidelity.

Windows may default to 8-bit—manually override it to unlock full color potential.

macOS sometimes restricts output—ensure "High Dynamic Range" is activated for compatible screens.

Driver bugs can artificially cap color depth even when hardware supports it.

Always preserve high bit depth throughout your editing pipeline.

Images saved as JPEGs with heavy compression often suffer from banding because JPEG uses 8 bit color and loses subtle gradients.

To prevent this, work in higher bit depth formats like TIFF or PNG during editing.

This gives you 65,536 levels per channel instead of just 256, drastically reducing banding.

Choose "Maximum Quality" or "Lossless" options whenever possible.

Set JPEG quality to 90–100% to minimize color loss.

Another common cause is improper color grading in video editing.

Use curves and levels cautiously on gradient-heavy areas.

A touch of film grain makes gradients appear organic and natural.

Most professional editing software includes a dithering option when exporting—enable it to add subtle random noise that breaks up visible bands.

Dithering tricks the eye into perceiving a gradient where discrete steps exist.

Calibration ensures you’re not overcorrecting for false banding.

Software-only calibration is unreliable—invest in a physical sensor.

Trust your eyes only after they’ve been calibrated.

Your workspace can amplify or conceal visual artifacts.

Sunlight or overhead fluorescents create glare that masks subtle gradients.

DIY hoods from foam board or professional kits both work well.

Also, avoid viewing content on screens with poor viewing angles, like some TN panels.

These technologies are superior for ریسو gradient-heavy content.

It’s rarely caused by one single factor—multiple elements interact to create the issue.

Fixing banding requires a multi-step strategy across editing, hardware, and output
