The problem with HDR is that the "photographer" hate the way people over process the images. The realization is that the people we show or sell our product to does no crap about what an image should look like. They don't understand composition, colors, and anything else we might want to discuss. They just know what they like when they see it. Many non-photographers enjoy the slight overprocessed stuff. They like the over saturations or extreme detail and textures. It's eye catching.

I am not talking about an image so processed that the colors are blown to the extreme or we've got halos around everything. But the slightly over saturated colors people like. Based on the product I see by new photographers already shooting weddings only proves my point. People are happy with crap because they don't know any better. Over and under exposed images with to much contrast are being sold as "professional" every day.

i don't like any editing for the images
i like them normal from the camera
i only use the software comes with the camera ( Digital Photo Professional ) and not all the time
this software is simple and easy

i use hdr all the time when shooting interior. Just had a client two days ago, that wanted to show hotel room interior with outside view of the city in windows. Light outside was 1/200 F9 iso200, inside 1/5, no to mention 3500K inside and cloudy outside. That sceen took about 15 shots and quite some editing. I dont use casual HDR process, but rather convert raws in ACR and use enfuse on tifs, to blend them together. It gives natural look and corrrect exposure. Im never tired of looking at bell shaped histogram of hdrs :)

My biggest issue with HDR is the abuse of the process. Meaning those who take the process to extremes and end up with an image that looks like a late 60's album cover instead of a photograph. I don't really care one way or the other why they do it, sometime it looks good in a surrealistic fashion, but it needs to be tagged with a different name than just HDR....

I consider what number six with his photos above to be HDR. I believe the surrealistic, cartoonish look is actually considered tonemapping (very similar process but very different results).

I can't say I hate tonemapping as a whole. It works for some images and produces very cool results, but I've seen plenty of overcooked examples that don't look so hot (and have admittedly ended up with a few myself through experimenting with it).

HDR is just another tool to use to capture a higher dynamic range that your eyes can easily resolve, but alas even the latest camera technology can't even get close (although it is improving). An average eye can see about 24 f stops! Now even the best camera today can probably do only a third of that. By taking several photos at different speeds you can try and simulate what the human eye can do so easily. Some photographers hate this as they like the way a camera renders an image and prefer the limits of the non human eye from an artistic point of view, and more proof to that is the abundance of B&W photos in an era where color is available. While others love HDR because they believe a picture should try to show what the human eye sees. IMHO both are correct and neither should criticize the other ... and although people will take both to extremes that should just be seen as a different type of artistic expression and accept it for what it is. I personally prefer the natural HDR, especially for blown highlights in skies or sunsets.

Simple and easy is best.
No editing is best.
I keep the lens cap on at all times to prevent the camera from editing.
Pure black is beautful.

Not editing a photo from a DSLR is just like accepting whatever processing that Walmart or Kmart give you during the film era. In a DSLR a camera decides a set of processing values to develop based on a perceived "best average" output. Now that doesn't always work out well because maybe there is a mix of different artificial lights and thus WB might be off, the shadows and highlights might also be off because of high contrast subjects and maybe the saturation used by the algo designer of the processing might be too much for your liking ... I could go on and on. With a DSLR you get to process the way you want the picture to come out, in essence your computer becomes the darkroom and where with film you needed a special lab and experienced technicians to get the output you want in a darkroom, with digital you have all the tools right on your computer without the cost and mess. Trust me that is very powerful stuff, and this is coming from someone that used to develop his own color film (trust me it is not easy).

Unfortunately, HDR became popular as a canned action from programs using (and rightly so) the RAW and giving the user some sliders to play with (I really don't know, in Darktable 3 RAWs are cooked into a DNG and then you can use and abuse the DNG to your heart's desire...). Been there... done that.

Recently, I stumbled upon a step by step HDR using JPG in GIMP (the Linux equivalent of PhotoShop). Now GIMP (in the version I am using) is a 8-bit editor, so I don't get the benefit of the RAW color depth, I've heard that the newer versions use 16 bit TIFF, but I am not ready for the upgrades.

Anyway, this method is described step-by-step here:

http://www.instructabl​es.com …otos-with-the-GIMP/#step1 (external link)

It is an easy process, very straightforward to duplicate in PS.

You can also use ONE JPG and darken/lighten it by 1-1.5 f-stops if you don't have a bracketed set of photos. Below I've done exactly this

The SOOC improved as a single jpg (stretching the exposure etc)

Machinery HDR is also very good at 1 photo HDR processing. I use it for single photos and if I know I'm shooting more than one photo to get HDR then I'll use Photomatix. But if you have a bunch of photos stored on the hard drive (and who doesn't) and want to experiment with one photo HDR then Machinery HDR is the way to go.

The method that is described in the site I quoted is the guts of the HDR actions most of the canned programs use.

If you use it, you can see the exact contribution of each base photo (high medium and low exposure) and you can manipulate each contribution in minute and different ways.

Of course you can make a 'canned' action out of this, but you are loosing so much in the process.
