Best Photos for a LEGO Mosaic: 7 Tips

Fill the frame with your subject. At 64×64 studs, a face that fills the picture gets thousands of studs; the same face in a wide shot gets a few hundred and loses its features. Crop before you upload, or pick a canvas shape that matches the subject.

Mosaics read by contrast: dark against light, warm against cool. A well-lit subject against a darker or plainer background works far better than a flat, evenly grey photo. The contrast slider in the studio can rescue a dull picture.

Busy backgrounds turn into speckles at mosaic resolution. A plain wall, sky or a blurred background keeps attention on the subject, and as a bonus it merges into large plates if you build with the Plates or Tiles style.

Harsh side light splits a face into a bright and a black half. Soft daylight from the front keeps skin tones smooth, and smooth tones are what the color matching handles best.

Icons and logos look great at 32×32. Portraits need around 64×64; group shots and scenes want 96×96 or more. Compare all sizes.

bricksmosaic matches every pixel against 34 real LEGO colors. For photos, dithering (Floyd–Steinberg or Atkinson) mixes neighboring colors to suggest shades the palette lacks. For logos, pixel art and flat artwork, set it to “None” for crisp edges and solid areas.

Bold, saturated colors translate well. Very subtle pastels and near-identical grays can fold into the same LEGO color. If two areas you care about merge, nudge saturation or brightness until they separate again; the preview updates live.
