One other "technical note" that might help:

EV stands of "exposure value". It is an interval of a camera's photographic exposure scale.

Outdoors with natural light - there is/are about 15 EVs visible.
The average point'n'shoot camera can only capture 5 or 6 EVs. (hence you get blown out skies when you shoot shadows or blacked shadows when you shoot skies)
An expensive DSLR type camera can capture perhaps 7-9 EVs. (hence why a good camera's photos look so much better than point'n'shoot!)

Say you had a really nice DSLR which could do 9 EVs.
By taking a photo at -2 EV, 0 EV and then +2 EV, you are now seeing 13 out of 15 visible EVs in natural light (you are adding 2 EVs below the normal photo and then adding 2EVs above the normal photo).
Pretty impressive and close to what you see when you are standing there - 13 versus 15.

This was the original intent of HDR. That said, it is difficult to pull exactly the data you want from each of the images (trying to get EV -1 and -2 and EV +10 and +11 exclusive data added into your EV 1-9 photo).
The HDR processing is supposed to allow you to pull the data from the 3 images and merge them. Because of the overlap in data that is visible in all 3 images, you often end up with "pop" because items in your image have 3 values that are all valid. How the end user chooses to merge (or process) this overlapping data is what determine's one's personal HDR style (the most famous perhaps of which was Ansel Adams way back when - and Trey Ratcliff in the internet age (and what most HDR images these days are styled after).

Ansel Adams was amazing in that he did HDR the "old fashioned way" with film!


Trey Ratcliff's style - made famous through his "Stuck in Customs" website



This is why when you look through this thread you can see many images that are very similar in style - they are using the same software/filters (i.e. algorithms) to merge the overlapping data.. and hence end up with something similar.

The same goes for tone-mapping (i.e. "coloring" a single image to give a similar style).

Clear as mud?



p.s. if you are interested in how Ansel Adams managed to do HDR pre-existence of computers.. you might enjoy this article:

Thanks for that link. I have always loved Ansel Adams work. I think his work really makes me want get out and see the world.

You are not messing up in anyway - I look forward to seeing more of your work!

Do you have any more photos of this bike? :


I'd love to hear your post processing steps

I see HDR photos similar to water color paintings with lots of detail. All varieties and techniques are nice to see.

Thank you.
I have learned what is HDR all about for some years. However I am just a squid in photography so never taken any real HDR. Yeah, you right, just color blending to get it looks (somehow) HDR for fun.

My CX650 cafe racer build thread has its link on my signature. Welcome to see and comment.

Because so many people "over process" HDR... the "overpopped" style has become known as "HDR"... but in reality most "HDR" photos these days are just tone mappings made to look HDR like; perhaps "HDR style" photography would be more apropos.
...


Hope this helps
I figured as much. Thanks.

HDR or *not* HDR, that is the question I ask

Not to belabor the point too much. I've tried to pull detail out of a few images. Where I've gone into Aperture, and created 2 new images from an existing one, +/- 2EV. I've been able to go creative, get artsy, but never actually improve the overall image.

Here are a few images I've capture using +-2 EV (usually exposure time), that there is no way I could have otherwise captured what my eye saw.


from:



I've taken a few pictures of bridges, where HDR has allowed me to pull out the detail of the beams. With just a single exposure, the rivets on right side of the image where barely noticeable, as they where in the shade. Pulling in the detail from the +2EV image really, IMNSHO, gives the image a lot more interesting detail.



The following image could have really used +-4EV as well, but without HDR there is no way I could get the bike and the center tree/clouds visible in the image.


I've still got A LOT to learn. To all of the other posters, and to Dave for starting the thread, THANKS, for inspiring me.

That is a terrific example of how HDR looks. Thanks. I understand now why my vacation pics NEVER look like when we was there.

From Nik Efex Pro 2

edit: I wanted to add, it really amazes me, the human eye can adjust fast enough, that when you scan over the surroundings you can see the detail. HDR makes it possible to see the image a lot closer to the way I see it.

From (-2EV, 0EV (standard), +2EV)


Gives:


You can see where the detail is pulled from each of the pictures. Not a lot from -2EV. In fact, a lot of the pictures, I do not include it. Especially if there is a lot of wind, I will just use 0EV and +2EV.

Nik Software HDR Efex Pro 2

Google has purchased the Nik Software and recently lowered the price to only $149 for the entire suite of their products.
I have always heard great things about some of their software, especially the Silver Efex Pro for black and white conversions.
So I downloaded a 15 day free trial to test it out. At first I didn't like any of the products. After a couple days I pretty much decided
that I wouldn't purchase it. However; the more I play around with it the more I like it. I really like the Silver Efex Pro and am even
starting to find how to get looks I like in HDR Efex Pro 2. It will not completely replace Photomatix Pro as I still think that is the
best HDR software, but I often end up with many photos looking the same by using the same software. I now have an option for
achieving different looks. I'll have to pony up the $149 when my trial runs out.

Here are two different sunsets from this week using Nik Software HDR Efex Pro 2.
