The conversion is only as good as the input. Most disappointing results trace back to the photo, not the tool.
| Factor | Good | Bad |
|---|---|---|
| Framing | Subject fills 60–80% of the frame | Subject is a small figure in a room |
| Lighting | Even, soft, no hard shadows | Direct sun, flash, one side in shadow |
| Contrast | Clear separation from background | Subject and background the same tone |
Crop before you upload. If the subject occupies a tenth of the photo, the design becomes an outline of a room with a small animal in it. Tight crops convert better at every style.
Hard shadows read as extra lines. Overcast daylight, or a window without direct sun, gives the cleanest edges. Flash flattens features and creates a hot spot that becomes a hole in the line work.
The subject needs to separate from the background by tone. A dark dog on a dark sofa will lose its outline. If you cannot reshoot, pick a photo where the background is clearly lighter or darker.
Upscale first, then convert. A 600 px photo upscaled to 2000 px and thresholded will look better than the same photo converted at native size and printed small.
