Thanks for viewing.
Any and all critiques welcomed.

Yes indeed. Each picture was merged and tone mapped using 3 bracketed exposures. It's my first HDR attempt.

Canon 30d
Tamron 17-35
 
could someone please clue me in as to what tone mapping is (with three bracketed exposures) and why one would do it and how to actually do it? Thank you!

I second the request. I'm thinking of getting the entry level Rebel XTi and want to start dabbling in still photography.

As far as your photos, Workhouse.., I think they're quite fantastic. I have an untrained eye, but I really like them.

This is the best tutorial I have seen on HDR.

In general I am not a big fan of HDR work, although for certain situations it is the only method through which to capture the image completely. In my opinion it just depends on the specifics that you are going for as to what is going to be the best method.

There are several ways to do an HDR image...

Take multiples with different shutter speeds and similar aperatures
Take multiples with different aperatures and different shutters
Take multiples with different exposure compensation

It is important that you are using a tripod and that you are trying to expose different parts of the scene. In my experience a good polarizer eliminates the need for HDR but some people are big fans of these.

Experiment, it's the best way to learn.
 
Thanks to all who replied. I couldn't agree more with you Jeremy on the polarizer eliminating the need. This was my first attempt using the same tutorials. I think HDR has its place and its nice to see so many different variations of it.

I think that an HDR contest sometime in the future would be a great place for anyone wanting to test these waters (if you havent already).

I may go out today and do some side by side comparisons of HDR vs Polarizer and post them for the sake of science. :thumbup:
 
Sometimes a polarizer wont always work, it just depends on whether you need to expose for the entire range. A great example of when you want HDR is for landscape stuff shooting from the shade to a bright area. This is a time when HDR is really the only alternative because a polarizer wont work well. For oceans and water a polarizer is just a better choice.

Because of the cost in doing HDR stuff in post production (having CS2 or one of the other merging photographs) an HDR contest excludes more people than it invites. I encourage everyone to play with some HDR stuff on their own but in my opinion it isn't inclusive but exclusive based upon ownership over post production tools so therefore I would not choose that as a topic for a contest... Just my $.02.
 
I sort of explained it with my HDR definition earlier... It is also custom function 12 on the D50.

Or a longer and more professional definition from dpreview.com

Bracketing is a technique used to take a series of images of the same scene at a variety of different exposures that "bracket" the metered exposure (or manual exposure). "Auto" simply means the camera will automatically take these exposures as a burst of 2, 3 or 5 frames with exposure settings of anything between 0.3 and 2.0 EV difference. This can be useful if you're not sure exactly how the shot will turn out or are worried that the scene has a dynamic range which is wider than the camera can capture. On a digital camera this can also be used to combine under- and overexposed images together to produce an image that could only have been taken if the camera had the same dynamic range as the scene, as shown in the example below. More about this in the tonal range topic.


When setting up for bracketing you can usually select the number of frames to be taken (typically 2, 3 or 5), the exposure setting and the order in which to take the shots (eg. 0,-,+ or -,0,+ etc.). It is important to note that the values are exposure compensation values.

The extreme example below was taken with auto bracketing of 5 frames at 1.0 EV in the -,0,+ order. Thus, in this case without bracketing the camera would simply have shot the frame with an aperture of f/4.0 and a shutterspeed of 1/160s. The +2.0 EV image was not used in the combination image.

Personally I just like to use the exposure compensation (because you use this all the time when shooting with the D200) and braket like that... -3, -2, -1, 0, +1, +2, +3 will give you a huge diversity of dynamic range and then just throw it all into photoshop cs2, go to file, automate, HDR merge and sit back and drink a long beer while it takes the 10 minutes to process with you setting only the white point... Pretty mindless but as discussed earlier, has it's uses for certain applications and scenerios.
 
I like your images, I think I like the old car one the most. I think HDR gives photos a "mystic" or "fantasy" like look which can be great for certain situations.
