Estimate daily active usage of Lightroom in a priority market

Problem Statement Description

Product context: Adobe is a creative, document, and marketing software company; its products include Creative Cloud, Photoshop, Illustrator, Acrobat, Adobe Express, Firefly, and Experience Cloud.

Adobe wants to understand the daily active usage of Lightroom in a priority geographic market for photographers. Your task is to estimate how many people actively use Lightroom on a typical day in that market, making clear what you count as “active usage” and which Lightroom surfaces are in scope, such as desktop, mobile, web, or cloud-connected workflows.

This is a guesstimate question, so the focus is not on knowing Adobe’s internal data. You should build a defensible market-sizing approach using reasonable assumptions about the photographer population, Lightroom adoption, paid versus free usage, professional versus enthusiast behavior, and typical editing frequency.

The estimate should account for Lightroom’s role in photography workflows: importing or syncing photos, selecting and editing images, applying presets, managing albums, exporting, sharing, or collaborating with clients. Consider that usage may vary significantly by user segment, device type, seasonality, and the intensity of professional work.

The experience should consider:

- The specific market being estimated and why it qualifies as a priority market

- The unit of measurement: daily active users, active sessions, or active editing users

- The relevant population base, including professional photographers, creators, hobbyists, students, and mobile-first users

- Adoption assumptions for Lightroom within that population versus alternatives such as native photo editors, Canva, Google Photos, CapCut, or other creative tools

- Frequency assumptions by segment, such as daily professional editing versus occasional hobbyist usage

- Differences between paid Creative Cloud users, Lightroom mobile users, and trial or free-tier users

- Sensitivity of the estimate to key assumptions like market size, creator penetration, and usage frequency

- Sanity checks against broader creative software adoption, smartphone photography behavior, and professional photography demand

The goal is to produce a structured, transparent estimate of Lightroom’s daily active usage in the chosen priority market, with clear assumptions, logical segmentation, and a practical range that Adobe could use for product, growth, or market-planning discussions.
