This is a test jump into HDR photography. Hopefully it develops as I learn more, but it was so interesting I just took a leap at it.
Faux HDR
- First off, I cheated at this. I took 1 picture (which wasn't really a great picture to begin with) and manually manipulated the colors to over & under expose. For the first test I wanted to see the merge results.
- The results were rich in color. I shifted between 2 exposure spaces and the latter of the two was the richest.
- Having seen the combined difference, I'll work on learning on the Powershot S3 how to manipulate the over/under exposure and see what a true light picture results with.
Real Test 1: Flower Pot
- Flower pot on Porch. I took this a few hours after the faux test. Much better
- Pictures one and two are cropped sections of the flower pot. Note the detail in the HDR version.
- Picture three is the full HDR picture
- Picture four is a combination of all of the exposures (marked) and a grayscale strip to show the differences.
Real Test 2: Tower
- 21 pictures ranging in exposures
- Noted that there is a need to drop overly exposed pictures (95% white) from the batch
Real Test 3: River
- 17 pictures ranging in exposures

Programs
- HDR Shop - V1 is free for non-commercial
- Photomatix - The older version is free (no tone tools)
- The latest version will save a non-watermarked HDR file.
- Combined with HDR Shop you apparently have all the tools you need.
- Photoshop C2 or higher
