Background Removal: The process of separating the jewelry item from its original background, creating a transparent or solid-color backdrop. Essential for e-commerce listings where a clean white or neutral background is required.
Batch Processing: Applying the same retouching operations to multiple images simultaneously. Batch processing dramatically reduces time when preparing large catalogs with hundreds of product photos.

C

Carat: A unit of weight for gemstones equal to 200 milligrams. Not to be confused with karat (gold purity). In photography, carat weight affects how a gemstone's size and proportions appear in images.
Catalog Consistency: Ensuring all product images in a catalog share uniform backgrounds, lighting, angles, and color balance. Consistency creates a professional, trustworthy shopping experience and is critical for brand identity.
Clipping Path: A vector outline drawn around an object to define its edges precisely. Used to separate jewelry from backgrounds with pixel-perfect accuracy, especially for complex shapes like chains and filigree.
Color Correction: Adjusting the color balance of an image to accurately represent the true colors of jewelry. Ensures gold looks gold, silver looks silver, and gemstone colors are vivid without being oversaturated.

Drop Shadow: A simulated shadow placed beneath the jewelry to give it a sense of depth and grounding on the page. Common in e-commerce photography to prevent products from looking like they float.
Diffused Lighting: Soft, scattered light that minimizes harsh shadows and hot spots. Created using softboxes, light tents, or translucent panels. Preferred for jewelry photography to reveal detail without overwhelming reflections.

E-commerce Photography: Product photography specifically optimized for online retail. Requires white or neutral backgrounds, multiple angles, consistent lighting, and high resolution for zoom functionality.

Focus Stacking: A technique where multiple images of the same subject are shot at different focal points and combined to create one image with complete front-to-back sharpness. Essential for close-up jewelry shots where depth of field is extremely shallow.

Gemstone Enhancement: Digital adjustments to improve the visual representation of gemstones in photos — increasing clarity, boosting color saturation, and enhancing the fire and brilliance of cut stones.

Hero Image: The primary product image displayed prominently on a product listing page. For jewelry, the hero image typically shows the piece from its most flattering angle with optimal lighting and styling.

Karat: A measure of gold purity where 24 karat is pure gold. 18K is 75% gold, 14K is 58.3%. In retouching, different karats of gold have different color tones that must be accurately represented.

Lightbox: An enclosed, diffused-light photography setup used to evenly illuminate small products like jewelry. Minimizes harsh shadows and reflections, creating a clean starting point for retouching.

Macro Photography: Extreme close-up photography that reveals fine details like gemstone facets, prong settings, and surface textures. Requires specialized macro lenses and is standard practice for high-end jewelry photography.
Metal Reflection: The mirror-like reflections visible on polished metal surfaces in jewelry. Managing reflections is one of the biggest challenges in jewelry photography — they can reveal studio equipment or produce unwanted glare.

Prong Setting: A gemstone mounting style using metal claws (prongs) to hold the stone in place. In photography, prongs must be sharp and clearly defined — retouching often involves cleaning up the appearance of prong tips.

Retouching: Post-processing adjustments to improve a photograph after it has been captured. In jewelry photography, retouching includes dust removal, scratch correction, sparkle enhancement, background replacement, and color correction.
Resolution: The amount of detail an image holds, measured in pixels (e.g., 4000×3000 pixels). Higher resolution allows customers to zoom in and inspect fine jewelry details. Most marketplaces require at least 1000px on the longest side.

Shadow Generation: Creating realistic shadows digitally after background removal. Shadows ground the product in space and add depth. Common types include drop shadow, reflection shadow, and natural shadow.
SKU Photography: Systematic product photography where each Stock Keeping Unit (SKU) receives standardized images. Jewelry brands may photograph thousands of SKUs requiring identical presentation for catalog coherence.
Sparkle Enhancement: Digital techniques to amplify the natural sparkle and brilliance of gemstones and diamonds in photographs. Involves carefully increasing highlight intensity at facet edges while maintaining a natural appearance.
Style Reference: A sample image that defines the desired visual look for a batch of retouched photos. Specifies background color, lighting angle, shadow type, and overall aesthetic. Used by Jewels Retouch to ensure every image in a catalog matches.

Turntable Photography: Using a motorized rotating platform to capture product images from multiple angles (typically 24–72 frames). When combined, these frames create a 360° interactive view for e-commerce listings.

White Balance: Camera or post-processing adjustment that ensures neutral colors appear neutral — whites look white, not blue or yellow. Critical in jewelry photography where even slight color casts misrepresent metal and gemstone colors.
