How to Photograph Tiny Products Sharp: Focus Stacking and Mixed-Surface Lighting Explained
Small products are the ones that humble you. You can have a perfectly dialed studio setup, a solid lighting ratio, a great camera, and a tiny object will still come back soft, flat, or weirdly reflective in all the wrong places. I learned this the hard way when I was helping my mom photograph her jewelry collection, back when she was still using iPhone snapshots and wondering why nobody was buying. The moment I introduced proper lighting and depth-of-field control, her sales shifted in a way that made the technical effort feel very worth it.
So when I came across this Visual Education tutorial by Karl Taylor on photographing small objects, I watched it twice. Karl is a commercial photographer working at a genuinely high level, and in this video he walks through a real-world shoot for an audiology company, specifically a hearing aid, which is about as technically demanding a small product as you can find. Mixed surface materials, extreme depth-of-field challenges, and high commercial stakes. Watch the full tutorial on YouTube and then come back here, because I want to break down exactly what he does and why it works.
Step 1: Assess Your Subject Before You Touch a Light

Before any light goes up, look at your product and ask one question: how many different surface types does it have? The hearing aid in Karl’s shoot had two distinct material zones, a glossy metal section and a matte plastic section. These two surfaces behave completely differently under the same light. Metal reflects specularly, meaning it acts like a mirror and shows the light source directly. Matte plastic scatters light diffusely and needs broader, softer coverage to show detail without going flat.
If you skip this assessment step, you end up chasing problems instead of solving them. Identify your surfaces first, then build your lighting plan around each one.
Step 2: Light Each Surface Type Separately

For the metal section of the hearing aid, Karl used a small, controlled spot light called a Picolite. Controlled, directional light gives glossy metal that clean, defined specular highlight that makes it read as premium. Too broad a source and the reflection becomes muddy or shapeless.
For the matte plastic side, he used a gradient light diffused through a scrim, which is essentially a translucent panel that spreads and softens the light before it hits the subject. That gradient creates gentle tonal variation across the surface, which is what reveals form and texture in matte materials. The key principle here is that each surface type has a “best light” and you find it separately, then combine both solutions into one setup.
Step 3: Add a Mirror to Control Catch Lights

One detail I want to flag because it is easy to overlook: Karl used a small mirror to redirect some of the gradient light back onto the product to create a specific catch light. Catch lights in product photography serve the same function they do in portraiture. They add life, dimensionality, and a sense of quality to the subject.
On a small object, even a tiny mirror or a piece of white card can make a meaningful difference. The mirror gives you directional control that a bounce card does not. Angle it precisely and you can place that highlight exactly where the surface needs it.
Step 4: Photograph Separate Components Individually
Karl explaining photographing each hearing aid separately
When your product has multiple pieces that sit at different distances from the camera, photograph them separately. Karl shot each hearing aid individually rather than both at once, because capturing both in a single frame would have required an impossibly large depth of field for a tiny object at close focusing distances.
This is a discipline issue as much as a technical one. It feels slower in the moment, but it gives you cleaner files and more control in post. Each individual shot can be optimized for that specific component’s lighting and focus needs, then composited together precisely.
Step 5: Use Focus Stacking to Get Edge-to-Edge Sharpness

This is the technique at the heart of the whole shoot. Karl captured nine separate frames of each hearing aid, each focused at a slightly different depth plane, then merged them using focus stacking software. The result is a single image where every part of the subject is sharp, front to back.
In practice, you need a macro lens, a tripod or copy stand, and either in-camera focus bracketing (most modern mirrorless bodies have this) or manual focus shifts between each frame. Shoot in live view, use a remote shutter or self-timer to eliminate camera shake, and overlap your focus planes generously. Nine shots for an object this small is not unusual. For more complex shapes or deeper subjects, you might need fifteen or more. Lightroom has a basic focus merge feature, but Zerene Stacker and Helicon Focus give you more control and handle tricky edges better.
Step 6: Composite the Final Image in Post

Once each component has its own focus-stacked, clean image, bring them together in Photoshop as separate layers. Use masks to blend the components naturally, paying attention to how shadows and reflections interact between pieces. If you lit each shot consistently, the composite will feel cohesive rather than assembled.
This is where good notes from the shoot pay off. Keep your light positions and settings consistent between setups so the color temperature, shadow direction, and highlight quality match.
What I Do Differently for Budget Setups
Karl’s setup uses professional studio equipment that most small business owners and solo shooters do not have on hand. But the principles translate directly to simpler gear. For mixed-surface small products in my own work, I use a combination of a strip softbox for the diffuse surfaces and a snoot or grid on a speedlight for the specular ones. A small dental mirror or a compact makeup mirror works perfectly for redirecting light to create catch lights.
Focus stacking is completely accessible without expensive gear. A kit lens at f/8, a $30 tripod, and free focus stacking built into Lightroom is enough to get dramatically sharper macro-style shots of jewelry, electronics accessories, or small cosmetics. The technique matters more than the price of the equipment.
The single most important idea in this tutorial is also the simplest: stop treating your product as one object and start treating its surfaces as individual lighting problems. Metal needs a different answer than plastic. One focus plane is never enough for a close-up subject with any depth. When you solve each problem separately and then bring the results together, you end up with images that look like they cost ten times what they took to make.
