Since 32-bit float pointing radiance map is also referred to as the digital HDR negative, Tone Mapping can be regarded as a kind of photo development, but for digital photos. ![]() "Tone Mapping" is the technology used to convert a 32-bit float pointing format to 8-bit images for display or print. Therefore, although a 32-bit float pointing radiance map records extremely accurate values, at this stage they are just meaningless numbers from the user's perspective because the results cannot be seen. However, a 32-bit float pointing value cannot be displayed or printed on current 8-bit monitors or printers. Camera HDR Studio could be one, but it has a lot of bugs and it doesnt really work as it should. Compared with conventional 8-bit image formats like JPEG or BMP, the 32-bit float pointing format has the capability to record a much wider range of values, and can thus accurately capture the full dynamic range of the real world. HDR PhotoStudio 2 helps you create beautiful high-dynamic-range images that look more like what the human eye sees. Photography apps are really popular on Google Play Store, but its difficult to find an app that lets you take nice HDR pictures with your phone. ![]() After the compensation of alignment and ghost reduction, photos with different exposures will be merged into a digital HDR negative, which is also called a 32-bit float pointing radiance map in the HDR imaging workflow.
