HDR

HDR, high dynam­ic range imag­ing, an imag­ing tech­nique devel­oped in the 1930s and 40s by Charles Wyck­off, using tone map­ping with brack­et­ed image expo­sures for a resul­tant image with a very high dynam­ic range. Var­i­ous meth­ods for HDR and HDR-like effects are now pop­u­lar with dig­i­tal photog­ra­phy. [wiki] [google]

Notable HDR images and image galleries

I think one of the best diy HDR shots on flickr is tos/uncommon/2264132877/in/set-72157603852146761/”>this one.
Some­times these HDR-like images look like a bright­ly-col­ored con­tem­po­rary paint­ing, such as this tos/13144640@N00/414895588/”>fantastic shot.

Smash­ing Mag­a­zine’s “35 Fan­tas­tic HDR Pic­tures” (scroll down). You can click on them and they’re pret­ty breath­tak­ing when seen large.

HDRcreme.com has rat­ed gal­leries. Do the to-gallery/?selection=rated”>rated gallery view first! One of my favorites — one of my favorite HDR photos ever — is this to-gallery/1343/”>capture of the Gris­wold Inn, Essex Con­necti­cut.

Good gallery of NYC in HDR.

“My first HDR” is a begin­ner’s group. It’s for your first attempt, and tos/70366873@N00/3333953452/in/pool-myfirsthdr”>some of the tos/lisarandolph/3333049431/in/pool-myfirsthdr”>results are quite fan­tas­tic.

HDR tutorials

This torials/high-dynamic-range.htm”>HDR tutor­i­al also dis­cuss­es when and why to use it.

The doc­u­ment “Recov­er­ing High Dynam­ic Range Radi­ance Maps from Photographs” con­tains many links to HDR pro­grams and tools.

“tos/cleever/145838011/”>Edit Away — The quest for a per­fect HDR” tells you how to do it with Photomatix soft­ware (for Win­dows).

On Flickr, you have to see this short, sim­ple tutor­i­al that shows “the tech­nique that Dave Hill and Jill Green­berg use on their photos with PhotoShop.”

An easy, quick way with Photoshop (and a tri­pod).

The GIMP, Linux, free software in general

The odd­ly-named Qtpf­s­gui is a true HDR imag­ing appli­ca­tion.

There’s a blog post on expo­sure blend­ing using only free soft­ware.

One free-soft­ware suite for HDR is tools/”>pfstools. There’s a dis­cus­sion on using it.

There’s anoth­er dis­cus­sion on fak­ing it. See also these step-by-step tutori­als on hand­made tone map­ping and sim­ple photo blend­ing.
You can do some­thing sim­i­lar by adjust­ing the inten­si­ty of the sky in a pic­ture.

You can fake it by blend­ing, if you only have one image: “tools.com/2008/02/how-to-create-hdr-images-in-gimp-with-a-single-image.html”>How to cre­ate HDR images in Gimp with a sin­gle image” [tools.blogspot.com/2008/01/try-exposure-blend-plugin-for-gimp-to.html”>more] [more] [still more]
