Developing persona - please make it 360° seam aware

Recommended Posts

HI all,

I often face the need to convert 32bit 360° panoramic image, created with the aid of stitching  software, into tone mapped 16bit image. Affinity Photo does a decent job performing this task, but it always creates the seam, clearly visible when edited panorama is displayed in 360° viewer. It is really disappointing. Yes, there is a workaround  - to duplicate the source panorama, offset it (wrapping around), make identical development, put it as a layer over first development (ofsetted after development) and use respective area from the second development to cover the seam.  But it is time consuming :(

Same for the tonemap persona. Editing with  it creates even more visible seam and sometimes a tiny, but noticeable 'vortex' around zenith and nadir points.  

I hope it is relatively easy to implement.

That's how the seam looks after the Tonemap persona.
