					<description>Hello, I 100% agree with Martin Tomes that you should all read The HDRI Handbook by Christian Bloch. It's a fantastic learning experience. 

Often when I see a HDR image it isn't really a HDR image... That's deep. It is most of the time some overly tone mapped exposure(s) pushed far beyond the range of what the data that was actually captured is capable of covering. 

There are 2 major problems with the HDR argument. 

One: What constitutes a HDR? How large of an EV range does an image need to have to be considered a High Dynamic Range image as opposed to a LDR?

And

Two: Your eye can see a much large range of light then the best digital or film camera can capture. So, when you look at a LDR image from your camera it isn't actually anything like what your eyes see in terms of EV stops. So your feelings about the realism or accuracy of HDR images is based on what we have grown accustomed to expecting in LDR exposures.
A properly constructed HDR will more accurately depict what your eye sees then a traditional LDR photo. We just aren't used to seeing images like that. For over a hundred years we have been stuck in a LDR world where we have to interpret what we see into a flattened contrasty, dumb down version of what is really visible to the human eye and we have taken that as the standard. 

Now I'm not knocking standard photography. I personally like high  contrast and silhouettes in my images. I do however think that most people are truly uninformed as to what a HDR image is and where it falls into the grand scheme of things.

Some Numbers:

Human Eye: 14 EV some even say it goes as high as 20EV but the standard agreeable figure is 14
HDR: as many as you want
FIlm &#38; Digital Sensor: 6-8 EV
Print: 6 EV


I would like to know what cameras are taking higher EV stops then the human eye.... We should all have one if it exists.</description>

					<description>Interesting perspective.  I'm late on the scene when it comes to HDR, as I only just starting hearing about it a month ago.  The results are impressive pictures, but I totally agree with all you said here - especially regarding whether they are photography or art.

Often when I see an HDR image I have to look closely to determine whether it is a photograph, a very detailed drawing, or a 3D render.  I'm a little bit wary of them for this reason, and I'd really rather people don't misrepresent them as anything other than HDR images.</description>

					<description>Well I agree with you on the parts that it becomes less about photography and more about imaging and processing but the thing is, think about what a Lightroom used to be in a sense, you'd sit there and twiddle with it and have different development times and preferences and just in general messing with it was fun. So now we're at the digital age with out film and the second part to Digital photography is Post - Processing. Some Photographers have enjoyed the development aspect to photography as well as taking the shot it self. 

all in all don't discredit HDR its just another field</description>

					<description>I'd put light use of HDR in the photography category, because darkroom processing has always been a part of photography, and can be used to pull different levels out of different portions of film.

My problem with HDR is that too many people, particularly tech geeks, focus on it instead of basic traditional photographic techniques for handling lighting, color, and timing. I've even heard people say things like "wow, that's a nice HDR!".

[I unfortunately also fall into this bin of tech geeks who know a lot more about camera equipment than photography. On that note, i'll also say that the latest and greatest of DSLRs has a higher dynamic range than the human eye, but lacks the brain for adjusting the exposure on the fly]

Display technology is limited, and print technology is limited in different ways, but a good photograph looks good on both.</description>

					<description>Hello and thank you, Grandma Friedl, for a diplomatic respons !  I guess I should have more regard for common usage. And yes, Jeffrey, 'separated by a common language' sums it up.

I'm not really such a stranger - I visit pretty much every day, but am shy of commenting on every post, though I enjoy all, be they plants, photography, family or just life in Japan !</description>

					<description>Well,   (Ahem!)   in  my opinion, I believe Jeff  and Peter are both right to a point.   "Provacative"  is of course from   " Provoke  ..to incline to anger."     Perhaps  "Evoke..to elicit or draw forth"    was the response   Jeff  hoped  to achieve.  But since I havn't the slightest comprehension  of the subject of   "HDR",  I can't really discern   what he means by any of it. I'll leave that to those who do.     (I just read these  posts looking for stuff about my Grandson Anthony)  It was just nice to see Peter here again.  Hi, Peter, don't be such a stranger.</description>

					<description>I'm going to go out on a limb by being so blunt: photography is not "art"; it is more correctly a "craft".  This is not to say it requires no imagination, creativity, nor skill -- quite the contrary.  But in the end, the proper application of photography does not create anything &lt;i&gt;new&lt;/i&gt;, but merely attempts to faithfully duplicate what the Mark 1 Eyeball perceived directly from the source.  Any application beyond  faithful rendering is where the "art" comes in.  

Most HDR is firmly planted in the "art" category, IMHO.

&lt;span class='jfriedl'&gt;Your summary seems completely reasonable to me. I'd only modify the last bit slightly, to suggest that there are thin, wispy tentacles of HDR that do venture into "photography" &#8211; the few cases where it really is used to get around current technical limitations &#8211; such as I did in the lanterns shot at the top of the post. &#8212;Jeffrey&lt;/span&gt;</description>
