Why wood is the easiest photo surface
If you have never engraved a photograph before, wood is where you should start. It is a dark-marking material: the laser scorches the surface, so wherever the beam fires you get a brown-to-black mark, and wherever it stays off you keep the pale bare wood. That maps perfectly onto how a photo already works - dark areas dark, light areas light - which means one thing that trips up beginners on other materials simply does not apply here.
You do not invert the image. The photo stays positive: you burn the shadows and leave the highlights as untouched wood. Compare that with slate, glass or anodized aluminum, where the laser makes a lighter mark and you have to flip the image to a negative first. On wood, what you see in the preview is what you burn.
Best wood for laser photo engraving
The laser can only reproduce tone cleanly on a surface that is itself an even, pale, tight-grained canvas. The perfect photo wood is light in colour (so the burn contrasts strongly), uniform in density (so the same power burns the same everywhere), and low in resin (so it chars cleanly instead of flaring). Five woods hit that brief:
| Wood | Why it works | Notes |
|---|---|---|
| Basswood | Very pale, almost no visible grain, soft and even | The gold standard for photo engraving. Burns fast, holds fine dots. Ideal first board. |
| Hard maple | Light cream tone, fine tight grain, dense | Sharper contrast and a more premium feel than basswood; needs a touch more power. |
| Birch plywood | Pale, flat, cheap, dimensionally stable | Great for practice and gifts. Use a quality laser-grade sheet - avoid glue voids near the surface. |
| Cherry | Warm even tone, fine grain, marks a rich dark brown | Beautiful for framed portraits; the darker base slightly reduces contrast. |
| Alder | Even, mid-pale, forgiving - a favourite for engraved plaques | Consistent burn; a solid all-rounder if you cannot get basswood or maple. |
If you are shopping for one board to learn on, buy basswood. It is cheap, pale, and its near-invisible grain means nothing competes with the portrait. Move to maple or cherry once your settings are dialled in and you want a more premium result. For the search term you probably typed to get here - photo engraving basswood - the answer is simply: yes, it is the best starting wood there is.
Woods to avoid
The woods that look most characterful on a shelf are usually the worst for faces, because the same features that give them character - wild grain, colour swirls, resin pockets - fight the photo for the laser's limited tonal range.
- Pine. Soft, but with a brutal density difference between the pale earlywood and the hard, resinous latewood stripes. The laser burns the two at completely different rates, so a face ends up crossed with dark bands. The resin also flares and leaves sticky soot.
- Oak. Gorgeous furniture wood, terrible photo wood. Its open, coarse grain and strong figure punch right through a portrait - you see the oak, not the person.
- Other resinous or oily woods (cedar, fir, some exotics). Sap and oils burn unevenly and can catch, and the strong natural colour cuts your contrast.
- Anything with heavy figure or knots where the detail lands. Dramatic cathedral grain is beautiful for a cutting board and ruinous under an eye.
The pattern is simple: the more visible the grain, the worse the photo. You want a board so plain it looks boring. That boredom is exactly what lets the engraved tone do all the talking.
Grain direction and how it wrecks faces
Even on a good board, grain matters. Wood is not uniform - the darker, harder grain lines absorb and scatter the burn differently from the pale wood between them. When those lines run across a smoothly graded area like a cheek or forehead, they show up as faint stripes right where you most want smooth tone, and the eye reads a striped face as "wrong" instantly.
Three habits keep grain from ruining a portrait:
- Choose the plainest face of the board. Flip it over and pick the side with the least figure. On plywood, use the cleaner veneer face.
- Mind the orientation. Running the engrave so the laser's fast scan lines travel along the grain rather than straight across it makes any residual striping less obvious, because the dot spacing and the grain no longer beat against each other as harshly.
- Prefer tight-grained woods (basswood, maple) where the grain lines are so close and faint they disappear into the dither. This is the real reason those woods win - not colour alone, but the absence of competing texture.
Surface prep: sanding, masking, coatings
A photo engraving is only as even as the surface under it. Ten minutes of prep is the difference between crisp tone and a blotchy, sooty mess.
Sanding
Sand the face smooth and flat - work up to around 220 grit and finish with the grain. A smooth surface burns evenly and gives fine dither dots somewhere clean to sit. Wipe off all dust before you engrave; even a thin film scatters the beam.
Masking
Apply low-tack masking or painter's tape across the whole engraving area before you burn, then peel it off afterwards. This is the single biggest quality upgrade for wood portraits. The tape catches the smoke and resin residue that would otherwise stain the pale highlights yellow-brown, so your bright areas stay bright and the contrast survives. Use a wide, thin, low-tack tape and burnish it down flat so no beam sneaks under an edge.
Optional light coat
On thirstier or slightly uneven woods, a very light sealing coat - a thin wipe of shellac or a sanding sealer, fully dry - evens out how the surface absorbs the burn and can deepen contrast. Keep it minimal; a heavy finish can flare or bubble under the laser. Always mask over the sealed surface, and test on an offcut first.
Image prep for wood
Because wood marks dark and holds detail well, the image prep is the standard photo pipeline with no inversion. In EngraveBot's Photo to Laser tool the sequence is:
- Grayscale. The laser ignores colour and only sees brightness, so convert first to see exactly what the machine will see.
- Contrast ~1.3-1.5×. Camera photos bunch their information in the midtones and look flat when burned. Push contrast until shadows read genuinely dark and highlights genuinely bright - it should look slightly too punchy on screen. Stop before the darkest areas collapse into featureless black; wood cannot recover detail you crush.
- Dither with Floyd-Steinberg. Most lasers cannot hold smooth gray on wood, so break the tone into thousands of pure on/off dots. Floyd-Steinberg's fine, tight grain suits the smooth surface of basswood and maple. If the dots merge into a dark smudge on a softer or darker board, switch to Jarvis or drop the DPI. The Dithering Lab previews both on simulated wood.
- Set DPI to your laser. See the tables below. Higher is not better - over-dense dots flood the wood and turn the face muddy.
Keep the background off the wood too: a busy background eats the tonal range the face needs. Cut it with the Background Remover, or read removing a background for laser engraving.

Starting settings by laser type
Here is the honest part every responsible guide has to say: the numbers below are starting points, not guaranteed-safe settings. Your exact power depends on your machine, lens, focus, the board's density and even the humidity that week. Use these to seed a test grid, burn it on the same wood as your real piece, and read the winning square off the board.
5-10 W diode
| Wood | Power | Speed | DPI / interval |
|---|---|---|---|
| Basswood | 15-25% | 2500-4000 mm/min | 254-318 DPI / 0.08-0.10 mm |
| Maple / cherry | 25-40% | 2000-3500 mm/min | 254-318 DPI / 0.08-0.10 mm |
| Birch ply | 20-30% | 2500-4000 mm/min | 254-318 DPI / 0.08-0.10 mm |
20 W diode
| Wood | Power | Speed | DPI / interval |
|---|---|---|---|
| Basswood | 30-45% | 3000-5000 mm/min | 318 DPI / 0.08 mm |
| Maple / cherry | 40-55% | 2500-4000 mm/min | 318 DPI / 0.08 mm |
| Birch ply | 35-50% | 3000-4500 mm/min | 318 DPI / 0.08 mm |
40-60 W CO2
| Wood | Power | Speed | DPI / interval |
|---|---|---|---|
| Basswood | 12-20% | 300-500 mm/s | 333-500 DPI / 0.05-0.076 mm |
| Maple / cherry | 15-25% | 250-450 mm/s | 333-500 DPI / 0.05-0.076 mm |
| Birch ply | 12-22% | 300-500 mm/s | 333-500 DPI / 0.05-0.076 mm |
Read these as a place to begin bracketing, not a recipe. A diode's percentage is meaningless across brands, and CO2 speeds vary with tube health. The Laser Calculator converts DPI, interval, physical size and engraving time so the arithmetic is done for you; the Test Grid Generator turns these ranges into a burnable grid in one click.
Single vs multi-pass
Photo engraving on wood is almost always a single pass. A photo is tone, and tone comes from dot density and per-dot dwell - not from going over the same lines twice. A second pass rarely adds detail; more often it over-burns the shadows, widens every dot, and merges the face into a dark blob. It also doubles your time and soot.
Reach for multi-pass only in narrow cases:
- Very dense hardwood where one pass at a safe speed cannot reach a rich dark. Even then, a slower single pass is usually better than two fast ones, because two passes rely on the machine repositioning identically.
- Deep relief work - but that is 3D depth-map engraving, a different technique from tonal photo engraving, and it uses a grayscale height map rather than a dithered image.
For a normal portrait on basswood, maple, birch or cherry: one clean pass, dialled in on a test grid, wins nearly every time.
Finishing the piece
The burn is done, but the piece is not. A few minutes of finishing lifts it from "engraved" to "framed".
- Peel the mask while the board is still on the bed, pulling at a low angle so no soot smears onto the wood.
- Brush off soot with a soft dry brush or a light wipe. On stubborn residue a barely-damp cloth or a whisper of isopropyl works, but keep water off bare wood or you will raise the grain and blur fine dots.
- Optional oil or wax. A thin coat of a food-safe finishing oil, hardwax oil or paste wax deepens the contrast dramatically - the burned areas drink it in and go richer while the bare wood warms slightly. Apply sparingly, wipe back, and always test on an offcut, because oil can bleed soot into highlights if you flood it.
- Seal if it will be handled. Coasters, boards and gifts benefit from a light protective finish so the engraving does not rub or yellow over time.
Frequently asked questions
What is the best wood for laser photo engraving?
Basswood is the best starting wood - pale, tight-grained and cheap - with hard maple, birch plywood, cherry and alder close behind. All are light, even and low in resin, so the burn reads as clean tone. Avoid pine, oak and other grainy or resinous woods whose figure and sap disrupt faces.
Do I need to invert a photo to engrave it on wood?
No. Wood marks dark, so the image stays positive - you burn the shadows and leave the highlights as bare wood. Inversion is only for light-marking materials like slate, glass and anodized aluminum, where the laser makes a paler mark.
What are good starting settings for a photo on wood?
Roughly: a 5-10 W diode at 15-25% power, 2500-4000 mm/min, 254-318 DPI on basswood; a 20 W diode at 30-45%, 3000-5000 mm/min; a 40-60 W CO2 at 12-20%, 300-500 mm/s, 333-500 DPI. These are only starting points - always burn a test grid on the same board first.
Should I sand and mask the wood first?
Yes. Sand to about 220 grit with the grain for an even surface, then apply low-tack masking tape to catch soot and keep the highlights clean; peel it after engraving. An optional thin, dry sealing coat can even out absorption on thirstier woods.
