Interesting list indeed!
By intensively using bracketing for years now i found out - for my own use and style of shooting of course - that 9 shot using 1 step difference is most appropriate when bright light-spots and deep shadows are in the scene.
Using PromoteControl i coud use up to 41 steps . . .
:cool: but thatÂ´s a bit extreme . . .
On the other hand i experienced that shooting straight into a sunset - or sunrise - most likely it takes 12 steps or more for getting it all covered smoothly.
In terms of panorama: itÂ´s a hell of a mass to shoot and process it all before stitching. Using my 85mm for a sphere it takes 200 shots@20% overlap . . . x9 or x12 . . i decided to use max. 5 steps then.
For non-panoramas or mosaics with few images itÂ´s doable with 12 steps in a time which allows to finish before the sun is gone away completely . . :-) - but: start early enough . .
