HDRView is a simple research-oriented high-dynamic range image viewer with an emphasis on examining and comparing images. HDRView currently supports reading EXR, PNG, TGA, BMP, HDR, JPG, GIF, PNM, PFM, and PSD images and writing EXR, HDR, PNG, TGA, PPM, PFM, and BMP images.
HDRView can display images in true HDR on Apple extended dynamic range (EDR) and 10-bit displays.
HDRView runs on macOS, Linux, Windows, and directly in your browser -- just go to wkjarosz.github.io/hdrview/ for the latest release version and wkjarosz.github.io/hdrview/dev for the development version. This even works on an iPhone or iPad! Try it out.

lt;h1 gt;What's Changed lt;/h1 gt;.
lt;ul gt;.
lt;li gt;.
lt;p gt;Restored support for writing OpenEXR images, and added reading/writing support for Ultra HDR JPEG images lt;/p gt;.
lt;ul gt;.
lt;li gt;Ultra HDR images will load both the reconstructed HDR image, and include the gainmap as a separate channel group lt;/li gt;.
lt;li gt;When saving to OpenEXR, will only save the visible channel groups of the image lt;/li gt;.
lt;/ul gt;.
lt;/li gt;.
lt;li gt;.
lt;p gt;Improved Images panel lt;/p gt;.
lt;ul gt;.
lt;li gt;choice of 3 views: 1) tree view of images/layers/channel groups, 2) flat list view of images/channels groups, or 3) flat list view of only images lt;/li gt;.
lt;li gt;can filter the images list by file and channel name lt;/li gt;.
lt;li gt;can sort the images list A-Z, or Z-A by clicking on the header row lt;/li gt;.
lt;li gt;can manually reorder the images via drag and drop lt;/li gt;.
lt;li gt;can hide the common portions of filenames lt;/li gt;.
lt;li gt;can now compare a current and reference channel group even if they are part of the same image lt;/li gt;.
lt;/ul gt;.
lt;/li gt;.
lt;li gt;.
lt;p gt;Improved Info panel with support to show and override the images chromaticities/color profile lt;/p gt;.
lt;/li gt;.
lt;li gt;.
lt;p gt;Channel statistics are now in their own panel. lt;/p gt;.

lt;li gt;.
lt;p gt;Three mouse modes/tools: 1) Pan and zoom as before, 2) Rectangular selection support, with histogram and channel stats updated to respect the selection, and 3) Pixel/color selector lt;/p gt;.
lt;/li gt;.
lt;li gt;.
lt;p gt;Viewport coordinate system change: current and reference image now have a common display window origin, but panning is still offset with respect to current image lt;/p gt;.
lt;/li gt;.
lt;li gt;.
lt;p gt;New Pixel inspector panel lt;/p gt;.
lt;ul gt;.
lt;li gt;lists and allows editing the rectangular selection lt;/li gt;.
