Wrong metadata information in exported stitched pano.

[liba...@gmail.com]

Hi.

Looks like no one use this way. But it worked perfectly in non beta PTGui.

I stitch to spherical pano from separate exposure brackets in PTGui end export them as 16bit tiff for merging in Photomatrix or Photoshop to HDRI.

Photomatrix now show me wrong ISO 1596 (all my images is ISO100) but show correct speed (1/4000, 1/500, 1/60, etc.)
Photoshop looks like can not even recognize exposure settings at all so it show me dialog that i need enter settings.

This is File info from 11 beta
