360 PhotoLab is an open-source Blender add-on for reframing equirectangular 360° still photos. It uses a camera-based workflow: load a 360° image, and the add-on sets up a Rendered view and Camera View automatically so you can compose a view. Framing controls cover yaw, pitch or vertical shift depending on projection mode, roll and horizontal field of view, with fine adjustment buttons for each.
The add-on offers RET, CIL and CLV projection modes and a comparative preview layout that places CIL and CLV on the upper row with RET centered below. An orthographic preview view drops the semi-transparent camera frame. Optional .cube LUT correction, resolution presets and print-size estimation round out the composition tools, and the final image exports as PNG, TIFF or JPEG.
360 PhotoLab handles seams robustly at ±180° and uses safer bilinear sampling around image borders. It is aimed at 360° photography, drone panoramas, virtual tours, landscape photography and print-oriented reframing workflows. Version 0.37.0 added an English menu.
