Digital matte painting

Two different jobs share the name

A set extension comes first. A real plate shows a real actor on a real build, and the build stops a few metres past the edge of frame. Everything beyond it is painted in, including the rest of the fortress, the drop to the water, and the ridge behind it, so the frame continues.

Any painted element must sit below the photography, not above it, and must match its lens, its haze, its grain and its light. If viewers notice the join, they stop following the scene and start watching its edge. The second job is a completely painted environment, where nothing in front of the camera was ever there: a coastline, a flooded city, a planet. In that case, the scene itself is the reference, rather than a plate. Both jobs draw on the same craft and differ only in how much of the frame was photographed.

How a painting is made

The sequence of steps differs from one vendor to another, but the basic pattern stays the same. The plate is the first input: it records what the lens did, where the horizon sits, how the light falls, and how far the camera travels. A locked-off frame can be painted as a flat image; a shot with movement cannot.

The paint is made for projection onto simple geometry matching the scene, and that is what lets a painted world hold its parallax while the camera moves through it. The painting itself is put together more than it is painted directly: photographic reference is cut, warped, repainted and blended until none of the seams survive; rendered geometry supplies whatever has to be exact; then everything is painted over until the separate origins no longer appear distinct. The test at each stage is whether the frame looks like a place a camera found instead of an image somebody produced.

What production-ready means

Looking good on screen at a comfortable size does not make a painting finished. To be finished, the painting has to hold up at full resolution with someone viewing it at 100 percent, has to stay correct on the projection through the whole camera move, and has to arrive in parts that a compositor can use immediately.

The result is a stack of layers, not one flat picture: sky, far ground, mid ground, atmosphere, and anything that has to move on its own. Most environment work is delivered as OpenEXR, the format maintained by the Academy Software Foundation at openexr.com, because a single file carries multiple layers and high dynamic range together. Chumak Studio delivers to the naming, colour space and pass structure that the pipeline documents specify, rather than to a house standard.

Why the spec changes between shows

Software versions are not the same across vendors, and those differences are not random. Once a year, the VFX Reference Platform, available at vfxplatform.com, defines the library versions that the industry agrees to use for builds. A delivery that was correct on last year's show can therefore be wrong on this one.

Colour behaves the same way. A production that chooses ACES as its standard, published through ACEScentral at acescentral.com, has already fixed the colour space for every vendor. Chumak Studio requests both answers before the first plate arrives, because together they define the delivery spec.

The work behind it

Overpainting beaches and cliffs, painting background mountain ridges, adding vegetation to the far cliffs, layering clouds, and replacing skies made up the House of the Dragon work as senior matte painter at Pixomondo across four episodes of the second season. The goal was scale without spectacle, so each plate had to appear as a real location, not a set piece.

Earlier features and series pressed the same craft into harder, wider service, from full-frame paintings and changes in season and weather to invented cities and coastlines, much of it completed as digital matte painter at PostModern Digital between 2018 and 2020. No part of this work comes from generation. Every element results from photography, rendering or painting.
