What is the ideal camera distance for vertical 9:16 4K creator video?

For a 24mm equivalent smartphone main lens (iPhone Pro / Galaxy Ultra), full-body 9:16 vertical framing requires 2.35m (7.7 ft) camera-to-subject distance at a 1.35m tripod height to prevent perspective distortion.

How far should an 18-inch ring light or softbox be placed?

Place key lighting 0.85m to 1.25m from the subject at a 30-degree off-axis angle. By the Inverse-Square Law (E = I / d²), moving a light from 1.0m to 2.0m reduces illumination to 25%.

How many 30x30cm acoustic panels do I need for a creator studio wall?

A standard 3.6m x 2.5m wall is 9.0 m². For 35% first-reflection acoustic treatment, you need 3.15 m² (35 panels of 30x30cm, or three 12-packs). Compute exact packs with Gapeye's Area-Based Packs calculator.

How do content creators calculate their home studio tax deduction percentage?

Divide the exclusive-use studio area (m² or sq ft) by your total home habitable area. For example, a 14 m² filming room inside an 80 m² apartment equals a 17.5% business-use apportionment.
