Creating a Sci-Fi Movie Poster – Part 1

Creating a Movie Poster, Part 1: Color, Light and Glow

Turning a straight-out-of-camera photo into a stylized, monochromatic movie poster look comes down to a handful of Curves and Blend If techniques layered together. This first part of a two-part series builds the coloring, shadow and highlight structure, and a glowing accent light, working from a reference image the whole way through.

Working With a Reference Image in Your Document

Keeping the reference poster open right inside the working document makes it much easier to judge how far to push each adjustment.

1. Bring the Reference Into Your Document

   Bring a reference image right into your document and press Cmd/Ctrl+T to resize it, keeping it visible as a guide for the dodging, burning, and color decisions to come.

Creating a Monochromatic Color Base With Colorize

The reference poster’s look is largely built on one dominant color rather than a full range of hues, which Hue/Saturation’s Colorize option handles directly.

2. Add a Hue/Saturation Layer and Enable Colorize

   Add a Hue/Saturation adjustment layer, click Colorize, then choose a blue-green hue and lower the saturation and lightness to taste.

3. Lower the Layer’s Opacity

   Reduce the Colorize layer’s opacity so some of the image’s original color information still shows through rather than a completely flat single hue.

Why the Colorize Layer Should Sit Above the Curves Adjustments

Placing the Colorize layer above the Curves adjustments that come next means it has the final say over the image’s overall color. If Curves layers sat above it instead, their individual color pushes could shift the final result away from the intended monochromatic look in ways that are hard to predict.

Darkening One Side of the Face

The reference image has one side of the face sitting almost entirely in shadow, which the current photo needs pushed toward as well.

4. Add a Curves Layer and Darken It

   Add a Curves adjustment layer and drag the curve down, then press Cmd/Ctrl+I to invert the mask to black.

5. Paint the Darkening In With a Soft Brush

   Using a large, soft white brush, paint over the side of the face that should read darker, without trying to define the whole image with this one layer.

Using Blend If to Create Natural-Looking Shadows

Painting a shadow in by hand can look flat and obviously edited unless it’s restricted to areas that are already dark.

6. Add a Darkening Curves Layer and Paint Into Shadow Areas

   Add another Curves adjustment layer, drag it down significantly, and paint it visible over the existing shadow areas of the face.

7. Restrict It With Blend If From the Right

   Double-click the layer to open Blending Options, and in the Blend If section, hold Alt/Option and drag the underlying layer’s white slider from the right toward the left, which hides the effect wherever the layer below is already lighter.

Why Blend If Makes a Painted Shadow Look Natural

A shadow painted directly onto the image with a brush shows up everywhere you paint it, including areas that are already light, which reads as an obvious edit. Restricting the effect with Blend If so it only appears where the underlying layer is already dark keeps the added shadow confined to areas that would realistically be shadowed in the first place.

Enhancing Highlights With the Opposite Blend If Range

The same technique works in reverse to bring out and strengthen the image’s existing highlights.

8. Add a Brightening Curves Layer

   Add a Curves adjustment layer and drag the curve up significantly, then paint it visible over some of the lighter areas of the face.

9. Restrict It With Blend If From the Left

   Open Blending Options again, hold Alt/Option, and this time drag the underlying layer’s black slider from the left toward the right, so the brightening only shows up where the layer below is already lighter.

Adding Small Specular Highlight Accents

A few very targeted bright spots add a final touch of dimension to the skin.

10. Add Another Curves Layer With a Narrow Blend If Range

    Add another Curves adjustment layer, and in its Blend If settings, bring the left-side slider in further to isolate just the very brightest points, then paint those in as small, specific highlight spots.

Why Small Specular Highlights Add Life to Skin

A few tiny, bright accent points mimic the way real skin catches specular reflections of light, which reads as more three-dimensional than an evenly lit surface. Grouping these highlight, shadow, and Blend If layers together with Cmd/Ctrl+G keeps them organized as one cohesive adjustment.

Adjusting Overall Saturation and Comparing to a Reference

A top-level Hue/Saturation layer gives final control over the whole image’s color intensity while comparing against the reference throughout.

11. Add a Top-Level Hue/Saturation Layer

    Add a new Hue/Saturation adjustment layer above everything else and adjust saturation up or down to taste, since a layer placed here overrides any color shifts introduced by the layers beneath it.

12. Compare Regularly Against the Reference Image

    Keep toggling back to the reference image throughout the process, using it as a guide for style and direction rather than trying to match it exactly.

Creating a Radial Glow With the Gradient Tool

A soft, colored glow in the corner of the frame adds one more atmospheric touch before the eyes and text are handled in part two.

13. Set Up a Radial Foreground-to-Transparent Gradient

    On a new layer, press G for the Gradient tool, open the gradient editor and choose the foreground-to-transparent preset, then select the radial gradient style and pick a color.

14. Drag Out the Glow and Set It to Lighten

    Click and drag to create the radial glow, then change the layer’s blending mode from Normal to Lighten so it brightens rather than darkening any highlights it overlaps, adjusting opacity to taste.

Why This Approach Works

Blend If is what makes every shadow and highlight adjustment in this tutorial look painted by light rather than by hand, since it automatically restricts each effect to areas that were already dark or already light in the underlying image. Building the monochromatic color base with Colorize above all the tonal work keeps that color consistent no matter how many Curves layers get added beneath it, and working from a reference image throughout, without copying it exactly, keeps the result guided without becoming a slavish reproduction. None of these techniques are unique to a movie-poster look either — the same Blend If and reference-driven workflow applies to matching any stylized look you find and want to learn from.

Final Thoughts

Getting a look like this right starts before Photoshop even opens — a photo lit with the right kind of directional, scraping light gives you something to actually work with, while flat lighting leaves nothing for Curves and Blend If to enhance. Part two of this series picks up with the eyes and the poster’s text treatment to bring the whole composition together.
