How much does light change between an outdoor ceremony and an indoor reception?

Commonly 6-9 stops — treat them as two completely separate lighting scenarios, not variations on one exposure.

Exposure Calculator for Wedding Photography

A single wedding day can span a 8-10 stop swing in available light — bright outdoor ceremony to a dim, string-lit reception — and each needs its own solved exposure.

Recommended settings

Outdoor ceremony, midday sun: EV 13-15 baseline.
Indoor reception with ambient lighting only: EV 4-7 — expect to solve for a much higher ISO or wider aperture.
First dance under string/spot lighting: meter the specific light on the dance floor, not the room average.

Tips for this niche

Re-meter every time the couple moves between rooms or from outdoor to indoor — don't carry one exposure setting across the whole reception.
When solving for ISO at the reception, decide your noise ceiling in advance so you're not negotiating it mid-speech.

Example scenario

The ceremony wraps at EV 14 in open shade. Twenty minutes later, the same couple is dancing under warm string lights reading EV 6 — an 8-stop drop. Solving for shutter speed at a fixed f/2.8 and ISO 3200 keeps the exposure correct without hunting for settings between songs.

Common mistakes

Carrying the ceremony exposure into the reception. the light level can drop 6+ stops walking from an outdoor aisle into a tented reception — re-solve rather than adjusting by feel.
Ignoring the room average and metering off the wrong surface. a white dress or a dark suit jacket can throw a scene's average brightness off — meter the couple's skin tone or a mid-grey reference where possible.
