Well Im stuck in the house with no car today so been messin with photoshop. Bill posted a thread with an HDR photo and I played around with creating an HDR project.
My camera does not have an HDR feature so I have to do it manually. Put camera on tripod in my house and took 8 photos of the same thing at a range of exposures. Even on a tripod its really hard to not move the camera while manually adjusting exposure between shots, the results are a blury image. But the concept here is merging a range of exposures to accomplish something a camera can not do in a single exposure. Next time if Im really serious about getting a sharp image, I will be much more careful of camera movement. Still a challange! (Cameras with the HDR feature take all these shots in rapid succession with one press of the shutter button.)
So heres the settup.
Inside my house with lights out but bright sunshine outside. The exposures used in these 8 images had a constant Aperture (which is essential). In this case the aperture was set at f/10 with a ISO of 400
The shutterspeed is what I changed and the fastest exposure was 1/800 with the slowest being 1/8 with a sequential change of shutterspeeds in between.
I loaded the 8 shots into Adobe Potoshop Elements 9 and used the Photomerge Exposure feature and let the software make the changes in AUTO mode. Im way too novice to do this manually.
(DISCLAMER. Im a babe in the woods with this stuff)
first exposure @ 1/800 shutter speed

and the 8 exposures automatically combined in Photoshop.

Then I thought the final product was too washed out so I went back and threw out the two most overexposed images and re-merged them. So this one used 6 exposures between 1/800 and 1/30
