Calibration studio for screens and projection

Your productions deserve to shine once installed.

Because a fine adjustment makes all the difference. Browser-based calibration studio — grid, live warp, mask painting, test patterns. No install. No proprietary software. Works with any projector or screen.

Immersive projection installation
Real situations. Real problems.
Real situations. Real solutions.
The AV technician doesn't show up — and you have no access to the projector's calibration software.
The projection spills onto walls, furniture, people. You need to mask specific areas, live, right now.
Your content warps on a curved surface — that floor, that dome, that angled screen — and you need to compensate on the spot.
You need to align content to the millimetre and you only have one shot to get it right.
You're far from the venue and someone sends you a photo of a misaligned grid asking you to fix it remotely.

About the creator
Built from the inside
of a real production.

A Grid With You was born from years of working on the ground — from pre-production to installation — and from the recurring frustration of not having a simple, fast, browser-accessible tool to calibrate projections without depending on proprietary software or a technician that may or may not show up.

This tool is the conclusion of optimized production and installation workflows. Every feature solves a real problem she has faced. Every shortcut saves time she didn't have. It is built by someone who has been on both sides of the screen — in the edit suite and in the venue, at 2am, with a projector that won't cooperate.

Laura D. is a Creative and Art Director specializing in audiovisual and multimedia experiences for museums, exhibitions and video mapping productions. With over 15 years of installations across Europe and the Middle East, she knows what happens when the technical rider meets reality on site.
