You may have already figured out by now that merging multiple images together means that it's pretty important that all our frames are taken from the exact same point of view, so a tripod is a must. Tripods and dog photography don't usually go together! I've played around with HDR images in the past, but with still landscapes or buildings. Not with a dog. That moves. Sometimes a lot! But this is a pet photography blog project and thus there needs to be a pet in my frame! 

Ginger's got a pretty good stay, but I wasn't convinced that she could hold perfectly still for multiple exposures (if she moves, the merged images will have a "ghost" effect on them where her body doesn't match up from frame to frame).  

So I had the bright idea to take several exposures of the scene and insert her into one where she would be correctly exposed.  After merging all the images without her, I would then put her in the scene via a little Photoshop magic.

You can see in the image with Ginger that she's perfectly exposed, however the shadows under the overpass contain little to no detail.  Additionally, I've got some blown out highlights where the sun is peeking through.
