okay so this is the dcraw2hdrgen(1) page from the General Commands Manual, and we're gonna get you fluent in it in like two minutes, no cap β¨
πΈ NAME πΈ
dcraw2hdrgen β parses the info inside the Digital Camera RAW files you hand it, and spits out a hdrgen script you can use to generate HDR images. it's giving "translator", and honestly? iconic. π
β¨ SYNOPSIS β¨
dcraw2hdrgen <file1.cr2> [<file2.cr2>...]
π¦ DESCRIPTION π¦
so here's the vibe: this program is your little automation bestie that creates an hdrgen script for you, all by itself, so you can use it with software that makes HDR images. no manual labor, we love that for us. π
the way it works is that the exposure information gets extracted out of the RAW files using the dcraw tool. that's the whole trick, that's the magic. π₯
but likeβ¦ if this script does not recognise the exposure settings from the pics your camera took, don't come for it first, come for dcraw first. π
to check, run this and see what's up:
dcraw -i -v your_image.cr2
you should be seeing some detailed info on the shot settings, including exposure time. if it's there, slay. if it's not there, that's your answer, bestie.
and ngl, maybe compiling the newest version will help. sometimes that's literally all it takes. π
π EXAMPLES π
here's the moment you've been waiting for:
dcraw2hdrgen IMG_0001.CR2 IMG_0002.CR2 IMG_0003.CR2 > sample.hdrgen
what this does: creates a sample.hdrgen script for the images you gave it. boom. main character energy, three files at once. π

lowkey obsessed with how simple this one is. go make some HDR images, you got this. π
and that's a wrap! this was the dcraw2hdrgen(1) page, straight outta the General Commands Manual β thank you for coming to my ted talk, mwah, bye bestie πβ¨ππ¦πΈπ
