A great product shot badly looks cheap; an ordinary product shot beautifully looks premium. Visual quality is the unsung hero of online sales.
Shoot near a big window with indirect daylight. Avoid mixed lighting. A white board opposite the window softens shadows for free.
Wipe the lens, lock focus and exposure, never use digital zoom — step closer. Edit lightly: brightness, contrast, white balance; keep colours honest to reduce returns.
Bottom line: window light + a shot list + light editing beats an expensive camera used carelessly.
