Xgrid Support
Photographing a screen usually fails: the camera’s sensor and the display’s pixel grid interfere and lay rippling bands across the picture. Xgrid takes a hundred frames in under a second, lines them up and averages them. The interference shifts between frames while the picture stays put, so averaging cancels it.
Getting good results
- Hold it in your hand
- The slight movement between frames is what cancels the pattern, so a relaxed grip beats a tripod. Resting the phone on something defeats it.
- Fill the frame
- Moving closer gives a better result than zooming in.
- Swipe to compare
- The second page is one untreated frame, so you can see exactly what was removed.
Questions
Why does it say “Too still”?
Because the technique needs a little movement. Held perfectly still, every frame is identical, the pattern lands in the same place each time, and averaging cannot remove it. Pick the phone up and hold it normally.
Why is the photograph black and white?
Most of the colour fringing on a photographed screen is the artefact itself, so working in monochrome discards it at the sensor and spends the available precision on tone instead. Colour capture is in Settings if you need it.
Can I use it on other things?
Yes. It is built for screens, but combining a hundred frames reduces noise on any subject, and the result is 16-bit monochrome with more tonal precision in the shadows than a single exposure.
