  1. ‼️ Big rayimage update (v0.23.0)! In addition to 'JPEG', 'PNG', 'TIFF', and 'EXR' files, `ray_read_image()` now supports loading 'TGA', 'BMP', 'PSD', 'GIF', 'HDR', 'PIC', and 'PNM' files (thanks to stb_image): It's a one-stop shop for bringing image data into R.

  2. 1) Keeping the exposure the same as the dawn image at noon: ooph!

    2) Adjusting the exposure down three stops with rayimage::render_exposure(): Nice!

    Also: this is why you use a high dynamic range format like EXR when rendering, which rayrender now supports! And also why I spent six months getting all the packages to install OpenEXR on the CRAN, so this magic can occur.

  3. Rendering a tilt-shifted Mount Everest at dawn:

    (dawn and dusk are the "magic hour" in rendering too, because you can represent an image in the dynamic range of a PNG/JPEG without clipping or tonemapping hacks!)

  4. Day 6 of the (3D), a render of Mount Rainier with a realistic atmospheric skydome generated w/ a lat/long/datetime, rendered entirely in with and ! The atmosphere is annoyingly realistic: I now have to dial in the exposure depending on the time of day! Thank goodness for 's render_exposure() function :)

    (someone really needs to create an HDR R graphics device...)

  5. ‼️New update: v0.17.1 has been released, and with it comes some cool improvements:

    * R console ANSI full-color preview if supported (Positron does on my system!)
    * Pretty printing for RGBA arrays!
    * Proper gamma correction tracking and EXR support
