Tone mapping operators with AI High Dynamic Range (HDR) is fast becoming the video format of choice for content providers, albeit not quite as quickly as thought. Standard Dynamic Range (SDR) displays still dominate the market. Therefore, efficient ways must be found to convert HDR content to SDR format, a process known as tone mapping. There are already numerous tone mapping operators (TMO for short), but these do not always lead to a usable result. Recently, many "new" TMOs based on deep learning approaches have been proposed. However, the main challenge in training such deep learning networks is the lack...

Thanks to new OLED material, cheaper OLED TVs soon? Based on new research results from the chemistry department at Pusan National University in Korea, the development of new OLED televisions could have a major impact on the price development of future models. OLED TV manufacturing currently uses a process called thermal vacuum evaporation, which is very labor intensive and very expensive in comparison. This is also one of the main reasons why OLED TVs are still more expensive than QLED TVs. Researchers at Pusan National University succeeded in synthesizing a solvent-resistant material for the hole-injection layer used in the OLED...

Will LG OLED TVs' Filmmaker mode get an HDR upgrade? The so-called Filmmaker mode allows viewers to watch movies the way the directors intended. However, it cannot be used to play Dolby Vision High Dynamic Range content. This is set to change soon. Filmmaker Mode in LG OLED TVs is currently limited to content in SDR and HDR10. However, the UHD Alliance is currently working with TV manufacturers to introduce Filmmaker Mode for Dolby Vision as well. The news was shared by Michael Zink, president and chairman of the UHD Alliance, which developed Filmmaker mode in partnership with Hollywood, at...

Exposure in a camera for HDR and SDR can basically be done in a similar way. Regardless of SDR and HDR shooting, exposure should be done correctly in mid-tone areas. For bright areas, however, things are different, and here the approaches already differ significantly. Thus, the brightness upper limit of HDR can very quickly appear "unnatural" or "disturbing". Therefore, it is important to reduce the upper brightness limits for shots that are planned for HDR in order to be able to better compensate for and edit, i.e. adjust, the brightness differences in the workflow afterwards.Contrary to the assumption that you...

With exception of the Arri Alexa 35, all cine cameras still only have a hardware-based (sensor) dynamic range (DR) of around 13 stops. However, using the log profiles of the camera manufacturers, it is possible to record up to 15 stops DR. However, this could change in the future, because Thomas Wocial, Konstantin D. Stefanov, William E. Martin, John R. Barnes and Hugh RA Jones have published a paper on the possibility of a new readout method for CMOS image sensors (CIS) entitled "A Method to Achieve High Dynamic Range in a CMOS Image Sensor Using Interleaved Row Readout". The...
