Fun with HDR
Lately, I've been playing around with a photography technique called HDR. I'm still in the beginning stages of learning how to do it, but I have had some successes so far, I think. For those who don't know, HDR stands for "High Dynamic Range" which means, unlike conventional photographs, there is a wider (higher) range of exposure levels in the image. So areas in a regular photograph under the same light conditions would have areas that were lost to over- (too light) or under- (too dark) exposure, which causes loss of detail. HDR photos are made by creating a composite of 3 images of the same scene that were taken at different exposures. I use the Automatic Exposure Bracketing feature on my camera and a free program called Qtpfsgui 1.8.12 to combine the images. However, this technique can be used with other programs like Photoshop, Photomatix, GIMP, etc. I hope to improve as I continue to experiment with different lighting conditions and program settings. By the way, this photo is of our dining room in the evening when the setting sun comes streaming in the glass door.
Here's what a single image looked like with regular exposure of the same scene under the same conditions. Notice the detail that is lost in the dark and light areas of this photo.

that's quite an improvement. good job.
Very interesting. I'm just learning to use my digital camera and a long way from such an advanced process.
Your shots are always so well composed and thoughtful.
