Photo studio HDR texture

Quick answer：

HDR (High Dynamic Range) textures are used in photography and digital imaging to create images with a wide range of luminance levels, from dark to bright, capturing more detail and a more realistic appearance. These textures are commonly used in post-production for enhancing the lighting and color depth in photos, especially in studio settings. They can be applied to 3D models or used as background textures in various software like Photoshop or 3ds Max.
