Are there any lighting conditions I cannot shoot under using the Rebel XTi?
There are few (if any) lighting conditions that can stump the Canon Reel XTi’s image processor. Presets include Auto, Daylight, Shade, Cloudy, Tungsten, White Fluorescent, Flash, Manual, as well as custom settings you can establish on your own. If you shoot RAW files you also have the ability to adjust the color balance long after the image is captured by re-opening your files in either Canon’s Digital Photo Professional (DPP) or Photoshop.
