HDR (High Dynamic Range)
Dynamic Range photography reveals all the
detail in a digital data file.
It can turn a dull image into a kaleidoscope of color and leave the impression that the photo is a painting, or it can rescue a picture that is too high in contrast and reveal detail that was hidden in the original. And it is easy to do. Here are three different HDR renditions of the same image.
Here's the same photo in JPEG without any editing.
Of course, this image could be improved by increasing the saturation and contrast. But bringing the tones of the image into a range where all of it is visible can only be done with a HDR creation program. To my eye, the Photographic HDR rendition is better than the unedited image to the right.
I use a program called Photomatix,Essentials but there are online programs that anyone can use. Here are several:

It required three images that were combined into this one final HDR image. That is the limitation for the average camera or camera phone user. Most of the time we take only one image of subject. But a HDR image requires three images, one that is under exposed, another that is correctly exposed, and a third that is over exposed. Some cameras are able to do this.
It is possible to get close to this effect by uploading three of the same image and allowing the program to work on those three images. The effect will not be as dramatic. But it will still be interesting.

It required only one image which was uploaded to the website and converted to a HDR-like image. You can see that it is different, but it is similar enough to have the HDR look.
The advantage of being able to make a HDR-like image from one original is that you can use pictures of people. It is difficult to get three images of people that are the same. People move. But if you can use just one image, that makes HDR-like pictures of people possible.
The truth is that is what I did with the pictures of the students above.

Which image is the best is a matter of individual preference. What HDR provides are alternatives to a the original image.
and camera phones can take HDR photos. If your
camera can do that, you may use that function for this
project. BUT one of the advantages of a "program" is
that it has many controls that allows you to change the
HDR photos in many, many ways. If your camera does not
have that ability, use an online program instead of the

the online programs and the Photomatix program I use
have a variety of controls. Explore the effects you
can get with different effects.
This Project gives you the opportunity to explore the creative world of HDR photography.
Begin by choosing one of the pictures you took on the field trip to downtown Olympia. Use one of the online programs, or one you have with Photoshop, and create an HDR image you like. That may mean you need to do several to get one you like. Upload both the original and the HDR image to Flickr.
Next choose a nature image you took earlier in the year, and do the same thing.
Next choose a picture of people, and do the same thing.
All the HDR programs allow for a variety of effects. Take one of the photos you've chose and make two other HDR photos from it using different effects.
Now, take a new picture that you think make an interesting painting-like image and create a HDR of that picture. Upload both the original and the HDR image to Flickr.
That will be a total of 10 pictures uploaded to Flickr. Put them in an album.
Finally, write a short paper (about 1/2 page type written) talking about what you liked or did not like about the final pictures.
