“…The projected panorama is a so-called single-line panorama, where the rotation is only perpendicular to the image plane. That means the camera does not need to tilt up and down to fill the remaining areas of the spherical panorama [16].…”

“…Figure 6 shows a panorama composed of many individual videos. [16] The compositional skills to create such a panorama with much motion are high, and the corresponding proprietary software is expensive, so customers can usually not execute these panoramas quickly. Therefore, these highly immersive panoramas can either be prefabricated or executed as commissioned work.…”

360-degree image and movie content has gained popularity in the media and the MICE (Meeting, Incentive, Conventions, and Exhibitions) industry in the last few years. There are three main reasons for this development. On the one hand, it is the immersive character of this media form; on the other hand, recording and presentation technology development has made significant progress in resolution and quality. Third, after a decade of dynamic rising, the MICE Industry focuses on a disruptive change for more digitalbased solutions. 360-degree panoramas are particularly widespread in VR and AR technology. However, despite the high immersive potential, these forms of presentation have the disadvantage that the users are isolated and have no social contact during the performance. Therefore, efforts have been made to project 360-degree content in specially equipped rooms or planetariums to enable a shared experience for the audience. One application area for 360-degree panoramas and films is conference rooms in hotels, conference centers, and other venues that create an immersive environment for their clients to stimulate creativity. This work aims to overview the various application scenarios and usability possibilities for such conference rooms. In particular, we consider applications in construction, control, tourism, medicine, art exhibition, architecture, music performance, education, partying, organizing and carrying out events, and video conferencing. These applications and use scenarios were successfully tested, implemented, and evaluated in the 360-degree conference room "Dortmund" in the Hotel Park Soltau in Soltau, Germany [1]. Finally, the advantages, challenges, and limitations of the proposed method are described.

According to our recent paper [1], the concept of creating a still image panorama with the additional inclusion of video footage up to 30k resolution has proven to be successful in various application examples. However, certain aspects of the production pipeline need some optimization, especially the color workflow and the spatial placement of the video content. This paper aims to compare two workflows to overcome these problems. In particular, the following two methods are described in detail:1 ) Improving the current workflow with the Canon EOS D5 Mark IV camera as the central device 2) Establishing a new workflow using the Apple iPhone 12 Pro MAX possibilitiesThe fundamental idea is to use ACES as the central color management system. This paper investigates if the direct import from Canon RAW to ACES2065-1 (AP0) via dcraw shows advantages to our current workflow using the sRGB/Rec.709 color spaces. In addition, we compare the conversion from Apple DNG RAW files to ACES2065-1 to the Canon Workflow. Also included is an investigation into whether the stitching process in PTGUI changes the original colors of the ColorChecker24 patches.Eventually, we investigate the SDR video import from the Canon EOS D5 Mark IV camera and compare the new workflow using ACES2065-1 as the central color space to the existing workflow in sRGB/Rec.709.

With the release of the Apple iPhone 12 Pro Max in 2020, various features were integrated that make it attractive as a recording device for scene-related computer graphics pipelines. The captured Apple RAW images have a much higher dynamic range than the standard 8-bit images. Since a scene-based workflow naturally has an extended dynamic range (HDR), the Apple RAW recordings can be well integrated.To correctly integrate the iPhone12pro Apple RAW data into a scene-related workflow, two command-line software solutions, among others, are dcraw and rawtoaces. In this paper, we concentrate on dcraw. dcraw offers the possibility to export RAW images directly to ACES2065-1. Different images recorded under different lighting conditions are examined to determine which options for the dcraw development produce the best results. Images from five different lighting situations like D65, D60, D55, D50, and 2980K, are examined. The DNG files are developed using different methods within dcraw. The values of the recorded ColorChecker24 patches are compared to reference values derived from BabelColor[1] and ACES[2].
