How to contribute correctly
A short photo guide so the OCR, stitcher and scorers see what's really on the pack.
Sativum fuses multiple angled photos of the same pack into one high-resolution composite. That means you don't have to fit a long ingredient list into a single frame — take several sharp, overlapping shots (~20% overlap) and the algorithm assembles them. It also unwraps cylindrical labels from 3–4 rotated shots. What matters is sharpness on the text, not clever framing.
Sachet
Soft foil pouches like spice sachets. Lay them flat on a matte surface, smooth out wrinkles, and shoot each panel head-on.
- Front — brand + product name
- Back — full ingredients list
- Nutrition panel (often on the back or side)
- Top seam & any side gusset for barcode / batch / origin
Square jar or box
Rigid rectangular packs like seasoning jars and cartons. Four flat faces — shoot each one square-on, one shot per face.
- Front label — brand & product name
- Back / left side — ingredients & allergens
- Right side / bottom — nutrition table
- Lid or bottom — barcode, batch, bio/organic mark
Round jar or bottle
Cylindrical packs like sauce jars and bottles. The wrap-around label needs four overlapping shots so the stitcher can unwrap the cylinder.
- Rotate the jar ~90° between shots (4 shots total)
- Keep the camera at label height, not looking down
- Overlap each shot by ~20% so text on the seams stitches cleanly
- Extra top-down shot for the lid barcode if present
Missing any of these forces the scorers to fall back on provisional data — which hurts your product page's rating.
Photography basics
Soft daylight or an indirect lamp. Avoid direct flash — it blows out foil and glossy labels.
The stitcher needs sharp letters. If ingredients look soft, retake — don't rely on upscaling.
Hold the phone flat above the panel. Angled shots skew text and confuse OCR.
Tilt the pack ~15° or move the light source. A single reflective streak can hide an allergen.
