Commercial photography: product, fashion and food

Visual Communication (B.Sc Visual Communication) · Photography · free study notes for exams, placements and interviews

In short

Commercial photography is image-making paid for by a client to sell a product, a brand or a service - unlike editorial or art photography, the brief, the usage and the deadline come from outside. Its three largest Indian segments are product/e-commerce (Amazon, Flipkart, Myntra, Nykaa catalogues), fashion/apparel (lookbooks, campaigns, e-commerce on-model) and food/beverage (menus, packaging, delivery apps, QSR chains). B.Sc Visual Communication papers examine lighting setups, studio workflow, styling, the difference between catalogue and campaign work, and the legal side - model release, copyright under the Copyright Act, 1957, and the ASCI code plus FSSAI advertising rules for food claims. Interviews at studios, brands and agencies test exactly this: can you light a reflective bottle, meet a marketplace's image spec, and hand over colour-correct, retouched files on time.

Key points

Formulas and examples

Exposure value: EV = log₂(N²/t) at ISO 100, where N = f-number, t = shutter time in seconds. One stop = a factor of 2 in light.
Light ratio from stops: ratio = 2difference in stops - a 2-stop key-to-fill difference is a 4:1 ratio.
Inverse square law: E ∝ 1/d² - E = illuminance (lux), d = light-to-subject distance (m). Doubling d loses 2 stops.
Guide number: GN = N × d - GN in m at ISO 100, N = f-number, d = flash-to-subject distance in m.
Field of view / magnification: m = image size / object size = v/u; object distance for a macro at 1:1 ≈ 2f from lens.
Depth of field (approximate, for distant subjects): DoF ≈ 2 N c u² / f² - N = f-number, c = circle of confusion (≈ 0.03 mm for full frame, 0.02 mm for APS-C), u = focus distance, f = focal length (consistent units).
Hyperfocal distance: H ≈ f²/(N c).
Diffraction-limited blur spot (Airy disc diameter): d_A ≈ 2.44 λ N - λ = wavelength (≈ 0.00055 mm for green light).
File size uncompressed ≈ pixels × channels × bits per channel / 8 bytes.
Shots per day = working minutes / minutes per SKU; per-SKU price = (studio + crew + retouch cost per day + margin) / shots per day.

Example 1 - inverse square law on a product set. A strobe is 1.0 m from a product and gives a correct exposure at f/11. The stylist needs the light moved back to 2.0 m for a bigger prop.

Example 2 - guide number for a speedlight packshot. A speedlight has GN = 36 (m, ISO 100). The light is 3 m from the subject.

Example 3 - lighting ratio for a fashion portrait. Key meters f/11 and fill meters f/5.6 at the subject, same ISO and shutter.

Example 4 - diffraction vs depth of field on a jewellery shot. A ring is shot on full frame; the photographer stops down to f/22 for depth.

Example 5 - catalogue job costing (per-SKU price). A studio shoots a 600-SKU apparel catalogue, 4 images per SKU = 2,400 images. One shooting day = 8 h with 1 h for setup and breaks, so 420 working minutes. Each SKU takes 7 minutes including dressing the mannequin.

Example 6 - file size for a marketplace upload. A 24-megapixel RAW cropped to 2,000 × 2,000 px is delivered as an 8-bit RGB JPEG.
