Each pair's files must have identical dimensions, matching exactly one of Instagram's feed
|
|
resolutions: <strong>1080x1080</strong> (1:1), <strong>1080x1350</strong> (4:5), or
|
|
<strong>1080x566</strong> (1.91:1). Assembling more than one pair downloads as a <code>.zip</code>.
|
|
HDR can be a regular gain-map JPEG or Lightroom's 32-bit float linear HDR TIFF export; a
|
|
TIFF HDR file gives a more precise result than the JPEG gain-map route.
