After being stunned by the close-up of the stars I'm tempted to download the 4.3GB original [1]. The scale was unexpected having mostly seen only resized photos

After being stunned by the close-up of the stars I'm tempted to download the 4.3GB original [1]. The scale was unexpected having mostly seen only resized photos before.

What program can open such file?
- ChrisGranger 12y ago
  That's a Photoshop Big file, which can be opened with Photoshop, obviously, provided your computer has sufficient RAM.

    So I guess it won't be of much use with my linux box...

      I've done some searching, but I haven't found any software that supports .PSB on Linux. Perhaps there's a plugin for The GIMP that would work, but I was unable to find one, sorry... It's probably more trouble than it's worth, but you could install Wine and Photoshop on your Linux box, or find someone with a Windows machine and Photoshop who could convert the file to another format that you're able to use, like .PNG for example.

      ImageMagick?: http://www.imagemagick.org/discourse-server/viewtopic.php?t=15672#p55807 http://www.imagemagick.org/discourse-server/viewtopic.php?t=...

      If the psb format can be converted to ppm format (via ImageMagick?), and image size is the issue, maybe NASA's BigView could be an option: BigView allows for interactive panning and zooming of images of arbitrary size on desktop PCs running linux. Additionally, it can work in a multi-screen environment where multiple PCs cooperate to view a single large image. Using this software, one can explore -- on relatively modest machines -- images such as the Mars Orbiter Camera mosaic [92160x33280 pixels]. http://ti.arc.nasa.gov/opensource/projects/bigview/ http://ti.arc.nasa.gov/opensource/projects/bigview/

  From previous experiments, any program that stores image data in quad-tree order (or even just tiles, but I hate tiles) should be able to pan around such an image with little effort even if you have only a fraction of the RAM but plenty of swap space. Of course zooming out will require either the full RAM or MIP maps. But IDK a specific app.

If anyone has succeeded in downloading the original from here or elsewhere...care to provide a mirror/torrent magnet link?
