I thought I would share this e-mail I received from Colin Smith.
Adobe has sneaked in some unreleased new features in Photoshop. These new features enable you to output a true HDR image for viewing on HDR enabled screens like monitors, iPads, phones and laptops including Apple XDR screens.
There is a new HDR Histogram, visualization, the ability to send a 32-bit image from ACR to Photoshop and more.
