You know that frustrating moment when you're trying to explain broad lighting to ChatGPT, but it gives you generic advice that sounds like it came from a photography textbook? You end up spending more time clarifying your vision than actually creating, and the results never match what you had in mind. It's like having a conversation with someone who knows the theory but has never held a camera.
These 12 battle-tested prompts transform your AI into a personal lighting consultant who speaks your language and understands real-world portrait challenges. From studio headshots to outdoor environmental portraits, each prompt delivers specific positioning, exact distances, and practical camera settings that work immediately. No more vague suggestions or endless back-and-forth conversations, just precise, actionable lighting setups that help you master broad lighting across every portrait scenario you'll encounter.
1
Studio headshot — soft broad lighting with large softbox
You are an expert portrait photographer. Provide a complete studio setup that uses broad lighting for a three-quarter headshot (shoulders and head). Include: gear list (lights, modifiers, stands), exact placement and angle of the key broad light (degrees from camera axis and height), recommended softbox size, distance (in feet/meters) to subject, fill light or reflector placement and distance, suggested power ratios or ND stops between key and fill, camera settings for 85mm and 50mm lenses (aperture, shutter, ISO), recommended metering method, quick posing notes to enhance the broad effect, and one short retouching note. Output as a concise step-by-step plan a photographer can execute in one session.
Practical studio recipe for producing classic broad lighting headshots with a large softbox. Gives exact positions, distances and camera settings for immediate use.
2
Outdoor broad lighting using strobe and silver reflector
Act as an experienced outdoor portrait photographer. Produce a step-by-step broad lighting setup using an off-camera strobe and a silver reflector. Specify: ideal time of day, strobe placement and tilt relative to subject and camera, strobe power settings (guide number example), reflector angle and distance, recommended lens and aperture for head-and-shoulders, tips to balance ambient and flash (flash sync or HSS settings), and two troubleshooting tips for wind and uneven light.
Outdoor recipe combining flash and reflector to create broad lighting that widens the face while balancing ambient light.
3
Hard broad light — dramatic editorial portrait
You are a studio lighting specialist for editorial portraits. Create a hard-light broad lighting setup using a small modifier (grid or 20" silver reflector) to create crisp shadow edges. Include: modifier selection, exact angle and height to produce broad lighting, distance, recommended power and camera settings for 35mm and 85mm, how to preserve texture without overexposing highlights, recommended background and one accent light (rim/hair) with placement and power ratio.
Instructions for using hard light to create an editorial, high-contrast broad lighting look, preserving texture and mood.
4
Beauty/fashion broad lighting with beauty dish
You are a fashion photographer. Outline a beauty-style broad lighting setup using a beauty dish modified for broad lighting. Include: dish size, optional grid or sock, exact position (distance and degrees), fill method (bounce card or hair light), camera settings for 50mm and 105mm, retouching brief for skin highlights, and styling notes (makeup and pose) that complement broad lighting.
A fashion/beauty-focused broad lighting setup using a beauty dish to sculpt and slightly widen the face, with practical styling and retouch guidance.
5
Three-quarter broad for masculine jaw definition
Act as a portrait specialist for male subjects. Provide a three-quarter portrait broad lighting plan to emphasize jawline and width. Specify: key light placement, angle that keeps the near-side cheek lit (broad principle), fill strategy to maintain shadow under jaw without losing definition, recommended focal length, aperture, and tips to use facial hair or collar to enhance lines.
Focused setup to make masculine features appear strong while using broad lighting to keep the face visually wider and defined.
6
Broad lighting with rim/backlight separation
You are an experienced studio lighting tech. Design a broad lighting scheme where the key broad light sits toward the camera side and a rim/hair light separates the subject from a dark background. Provide: positions and heights for both lights, power ratio (key : rim), suggested modifiers and gels (if any), recommended distances and grids for the rim, and camera settings for low-key exposures.
Combines broad key light with a rim light to maintain subject/background separation for punchy portraits in low-key setups.
7
Group portrait — applying broad lighting to one subject in a trio
You are a portrait photographer working with groups. Provide a lighting plan that applies broad lighting to the central subject (three-person group) while keeping consistent light on the others. Include: key placement that favors the center (broad on center face), fill lighting or reflectors for flank subjects, recommended distances and umbrella/softbox sizes to cover the group, camera settings to maintain depth of field, and quick posing layout.
Practical group-lighting plan that ensures the central subject receives a broad-lit look without leaving side subjects underexposed.
