Focus Stacking for Miniatures: Keeping the Whole Model Sharp
Focus stacking combines photographs taken at different focus distances so more of a miniature appears sharp in the finished image. Keep the model, camera, framing, and lighting fixed, then move the focus gradually from the nearest important detail to the farthest. Software blends the usable sharp regions into one composite.
This is useful when a spear tip, face, and backpack cannot all be sharp in one close photograph. It is also useful for a model car seen from the front corner or a long locomotive photographed at an angle. It does not replace careful lighting or turn a sequence of blurry frames into a reliable record.

Check whether you need a stack
First try a single frame from slightly farther away, a less oblique angle, or a composition that puts important details at more similar distances from the camera. Those changes may produce a perfectly useful photograph with much less work.
On a camera with adjustable aperture, a smaller aperture can increase depth of field, but stopping down too far can reduce fine definition through diffraction. Nikon’s focus-shift explanation describes the reason stacking can be preferable to simply choosing the smallest aperture.
Keep a single frame when its selective focus serves the image. A close portrait of a painted face may look better with the rear of the figure soft. Stack when front-to-back information matters, rather than making every photograph maximally sharp by habit.
Prepare a subject that will stay still
Place the miniature on a secure surface and mount the camera on a stable tripod or stand. Turn off a nearby fan if it makes banners or foliage move. Check for a loose base, rotating turret, rocking wheels, or a dangling part that might change position between frames.
Use steady continuous lighting or a flash arrangement that repeats consistently. Avoid a session beside a window with rapidly changing sun and cloud if you need a long sequence. Finish moving lamps and reflectors before starting.
Allow a little extra space around the whole model. Alignment may need to shift or scale frames slightly, leaving edges to crop. A sword tip touching the edge in the first frame gives you little room to correct the combined image later.
Choose a capture method your equipment supports
| Method | How it works | Main check |
|---|---|---|
| Manual focus series | Change focus in small steps without moving the camera | Each new sharp region overlaps the previous one |
| Camera focus bracketing | A supported camera advances focus automatically | Its start point, step behavior, and lens compatibility |
| Focusing rail | Move the camera in measured increments | Framing and perspective changes remain manageable |
| Phone manual-focus series | A supported camera app lets you select different focus distances | The phone keeps the same camera, framing, and exposure |
Automatic focus bracketing and in-camera focus stacking are different features. A camera may record the source sequence but require separate software to combine it. Read the instructions for the exact camera and lens before assuming it will deliver a finished composite.
For a first attempt, manual focus is easy to understand because you can watch the sharp area move. A rail becomes more useful when the required changes are too small to control comfortably on the lens. Do not move both the rail and focus ring unpredictably during the same learning exercise.
Capture a sequence with no missing depth
- Set the framing. Include the complete model and the space you intend to keep.
- Choose consistent exposure. With manual controls, fix aperture, shutter speed, ISO, and white balance. On a phone, lock the available settings and watch for automatic lens changes.
- Find the nearest detail. Start at the closest part you want sharp, such as a bumper, weapon tip, or front edge of a base.
- Take the first frame without touching the setup. Use a timer or remote release where available.
- Advance focus a small amount. Inspect the overlapping detail at enlarged view, then capture the next frame.
- Continue past the farthest required feature. Check the final frame rather than assuming the sequence reached it.
- Review the source frames. Make sure every important feature is sharply recorded somewhere before dismantling the setup.
There is no dependable universal frame count. A shallow model view might need a modest sequence; extreme close work can need far more. For a practice session, select a manageable subject and judge the count from visible overlap, not a preset promise that ten photographs will be enough.
On an interchangeable-lens camera, an aperture around f/5.6 or f/8 can be a reasonable experiment, but it is not a requirement. Sensor size, lens, magnification, and desired output affect the choice. Many phones do not offer adjustable aperture, so do not look for a setting that your device lacks.
Blend the frames in software you already have
If you use Photoshop on desktop, place each source image on its own layer, select the relevant layers, align them, and then choose the stacking blend method. Adobe’s documented sequence uses Edit > Auto-Align Layers, followed by Edit > Auto-Blend Layers > Stack Images. See Adobe’s extended-depth-of-field instructions for the current desktop workflow.
If the blending command is unavailable, check the document and layer types. Adobe states that Auto-Blend supports RGB or grayscale images and has restrictions on Smart Objects, video, 3D, and Background layers. Its Auto-Blend overview lists these limitations. Keep copies of the original files before converting layers.
A simple stack can also be assembled manually in an editor with layers and masks. In GIMP, for example, a layer mask can hide the soft part of an upper image to reveal a sharper lower image. White on the mask shows that layer; black hides it, as explained in the GIMP layer-mask documentation. This is a hands-on alternative for a small, well-aligned set, not an automatic stacking command.
Inspect the composite where software struggles
View the result at full size and inspect projecting parts first: railings, whiskers, antennae, sword edges, wheel spokes, rigging, and clear canopies. Check both sides of each outline. Fine details in front of a distant surface are useful places to find missed blends.
| Visible problem | Likely next step |
|---|---|
| A soft strip across the model | Find whether any source frame contains that strip sharply; reshoot with smaller focus steps if none does. |
| Double edges | Check for subject movement or poor alignment before changing the blend. |
| Halo around a thin part | Use the cleanest source frame to refine that region with a mask. |
| Patchy brightness or color | Check exposure, white balance, and lighting consistency across the sequence. |
| Missing corners or cropped tips | Crop conservatively, or recapture with more space around the subject. |
A mask can repair a blend only when suitable detail exists in a source frame. If every photograph missed the rear handrail, sharpening cannot reconstruct a trustworthy view of it. Reshooting is the more dependable solution.
Save a result you can revise
Keep the original sequence in order, the layered working file if practical, and a separate finished sharing image. Record the camera, lens, approximate distance, lighting arrangement, and number of frames. Include a note that the finished image is a focus stack in your private build record.
For a collection or sales photograph, retain the actual finish and condition. Combine focus information without replacing decals, erasing wear, or inventing unseen detail. If the photograph is being used as evidence of a technique or result, explain that it is a composite.
Start with one model before applying the method to a whole collection. The LootBandit hobby buying guides offer a place to plan projects; a small photography trial lets you learn what your existing equipment can do before adding more gear.
Frequently asked questions
Is focus stacking the same as HDR?
No. A focus stack combines different focus distances. HDR normally combines different exposures to handle a wide brightness range. A stacking sequence should usually keep its exposure and lighting consistent while focus changes.
Can I stack photos taken with a smartphone?
Yes, if you can capture stable frames at different focus distances and combine them later. Manual focus availability varies. Avoid automatic camera switching, keep the phone fixed, and check that each required detail is sharp in at least one source frame.
How many photographs should I take?
Take enough to cover the required depth with overlapping sharp regions. The number depends on magnification, aperture, subject depth, and focus step size. Check the source frames before packing away the model; a fixed number cannot guarantee coverage.
Why are thin parts still surrounded by halos?
Fine foreground parts and the background behind them can be difficult to blend cleanly. Inspect the original frames, refine the mask using the best source, and reshoot if the necessary detail was never captured. More sharpening is rarely the first useful fix.
