HDR – High Dynamic Range Imaging
The XZ-1 does not have in-camera HDR. It does have automatic bracketing, where it
takes three pictures at different EV levels, that you can later put on different layers in
Photoshop or Paint Shop Pro to create the HDR effect.
High dynamic range. In some situations, you can increase your dynamic range by double-
processing the same RAW file. First, process the original capture to bring out the
shadows. Then go back to the original RAW file and process it a second time to control
the highlight values. Blend the two files into one image, and you'll end up with a
dramatically higher dynamic range. While in the field, it's better to expose for the
highlights in one capture and the shadows in the next and process those together, but a
great deal of contrast problems can be solved even if bracketing isn't done during
capture.
HDR tips from Rick Sammon --
No matter what type of HDR images you are looking to create, here are some basic
guidelines that can ensure the best possible results.
• Keep your aperture constant and instead bracket by adjusting shutter speed.
• Use a tripod whenever possible for best all-around results.
• If you must shoot handheld, position yourself so you can hold the camera as steady as
possible.
• Use the onscreen histogram to make sure you have captured the entire tonal range of the
scene.
• Resist the urge to open up the shadows too much. Without rich shadows, images simply
look flat.
XZ-1 Auto Gradation
XZ-1 Gradation? Well -- in a way, it is HDR. Sort of. The differences are subtle ...see my
pic below (interior, low light, Vivid color mode). But key thing to remember -- if you use
Gradation on Auto, you cannot use the Spot meter setting. Using Normal (gradation Off),
High Key, and Low Key... the Spot meter still works.
