I’m fine with option 2.
I also want to add that I did a test shot yesterday of a bottle of black currant lemonade (instead of some fancy liqueur) lighted by a candle. The candle light moves ever so slightly during the exposure and there were some fine details on the label on the bottle.
The auto setting picked up everything around the candle but also all details on the label which looked very good with all motion correction set to off. So I figured I would try to get some balance by adjusting the settings. At first it seemed impossible to get both a clean label and smooth area around the candle. Had it been a serious picture I figured I would probably have to blend it manually.
But all of a sudden I found a setting that worked perfectly (on this particular picture). Unticking the red/blue detection and increasing the blur area, increasing the blending (can’t remember the exact labels) and the mask magically picked up exactly everything I wanted and left the label untouched. The area around the light was perfectly blended from a single image to PS and the label was pure PS.
Impressive! (I posted the picture at pentax forum, K1, Pixelshifted images).
