I am really keen to try some of this, take three raw pics at different exposure levels then use Photoshop to process the info from all three to give a foundation image for you to tweak further.
I took some pics in the summer and had a fiddle.
Pic 1 – Exposure 0.00
Pic 2 – Exposure -1.67
Pic 3 – Exposure 1.67
Which when imported into Photoshop CS2 using the /Automate /Merge to HDR function gave me this:
Not a great result, but as it was more of a “suck it and see” test you can see the differences. Note that a true HDR photo is 32bit psd which means it has twice the amount of data then a 16bit jpg, so there is some deterioration when you convert to jpg, but I didn’t notice too much in this example.
You can see in the Stella example that the foam sitting on the beer in the bottle is a lot punchier than either of the three originals. Also the colour and contrast of the label is different. Need to play about a bit I guess (and invest in a tripod (and find a willing cow))
