01 · HANDWOVEN COTTON
Weave you can count.
Flat front light erases the weave and the uneven threads that make it handmade.
Where the light goesLight low and to the side, so it rakes across the weave.
MATERIAL · SOL 30W
Cotton, leather, copper and glaze, lit with one Sol 30W. How to light each one so the photo matches the material — and why a CRI number alone isn’t the promise.
CRI 96 · TLCI 96 · 6.3 IN DIFFUSED SURFACE · 2700K–10,000K
IN ONE ANSWER
It is the starting point, not the whole answer. Harlowe Sol 30W measures CRI 96 and TLCI 96, so it renders colour closely under test. What ends up on a product page also depends on the camera’s white balance and the edit. That is why we set white balance in camera, keep the frame straight out of camera, and list every edit.
FOUR MATERIALS
Each material fails in a different way under poor light. Here is what goes wrong, and where we put Sol 30W to keep it true.
01 · HANDWOVEN COTTON
Flat front light erases the weave and the uneven threads that make it handmade.
Where the light goesLight low and to the side, so it rakes across the weave.
02 · LEATHER
Hard light turns the surface into one glare spot, and the wrong white shifts the tan.
Where the light goesLight higher and further off-axis, the diffused surface kept close for a soft highlight.
03 · COPPER
Small, hard sources leave hot pinpoints and cold grey mid-tones along the curve.
Where the light goesLight close, so the round surface reads as one smooth highlight along the curve.
04 · TEA WARE
A glaze mirrors the light as a white disc; dark glazes go muddy.
Where the light goesLight behind and above, a white card in front to fill the body of the piece.
HOW WE SHOOT IT
Sol 30W measures CRI 96 and TLCI 96. That tells you how the light renders colour under test. It doesn't tell you how your camera, your white balance or your edit will treat it — so we record all three for every photo.

QUESTIONS, ANSWERED
Sol 30W is rated CRI 96 and TLCI 96. The product page lists the same rating for the Standard Kit and the Adele Chan Spectra Creator Kit.
The Standard Kit runs 2700K–6500K. The Adele Chan Spectra Creator Kit runs 1700K–10,000K and adds RGBCW colour with full HSI control. Both dim continuously from 0–100%.
Place the light low and to the side so it rakes across the surface; flat front light hides weave and grain. A diffused source such as Sol 30W’s 6.3 in surface keeps the highlight soft instead of a single glare spot.
Matching the camera’s white balance to the light’s colour temperature means the raw frame already shows the material’s real colour, so the edit only has to adjust exposure or crop.
For neutral white-light product work, the Standard Kit ($249) covers 2700K–6500K. Choose the Adele Chan Spectra Creator Kit ($399) if you also match warm interiors or cool daylight, or add colour.
