If you are using 32-bit editing for lossless workflows (e.g., 3D compositing/rendering) where you are not compressing or modifying the tonal range, you can use the 32-bit Preview panel to preview different areas of the large 32-bit tonal range. Viewing and editing high dynamic range imagery in conjunction with an HDR or EDR compliant display.Useful for fine gradient work, heavy tonal manipulations and composite work. General image editing and design work with increased precision.Full renders and buffer passes from 3D software and 3D engines can be professionally color managed and edited losslessly. The result typically has to be tone mapped in order to be viewed properly on most displays. HDR merging from several exposures to produce an image with greatly increased dynamic range.See the 32-bit Preview panel topic for more information. Support is included for HDR (High Dynamic Range) or EDR (Extended Dynamic Range) compliant displays, enabling a much higher peak brightness to be displayed on-screen. For example, highlight detail blown out by an adjustment or filter can be recovered even after successive operations. This means the information can be modified to extremes without losing fidelity or accuracy. Compared to 8-bit or 16-bit, 32-bit presents an unbounded color space that can contain a vast amount of tonal information. Affinity Photo has full support for 32-bit float editing, including import/export for OpenEXR and Radiance formats.
