Thanks everyone, useful stuff!

You are welcome.

I already had a good grasp of ETTR and even use uniWB sometimes, thanks to DM. But for the situations that that is not adequate, could someone share their preferred ways of stacking and merging? And maybe explain some of the differences....not the implications, of equal and HDR exposure, I get that, just how do you stack and merge and with what settings if needed.

Not sure exactly what more you'd like to know apart from what I already said. But practically speaking, the software I use at present is LR/Enfuse which works quite well in my experience so far and has the advantage of a) being cheap (a "donation" of 2 GBP is required) and integrated with LR (LR plug-in). The only significant disadvantage I have noticed this far is that it takes a while for it to do the number-crunching (we are talking minutes rather than seconds) even on my new and pretty fast PC. But I don't know if other options are faster.

I would normally use the default merging parameters, which in the case of exposure bracketing weighs the contribution of the various shots to the rendering of a particular area in the frame based on how optimal the exposure of that area is. When merging shots at the same exposure, it doesn't matter what parameters you use since the shots are practically identical.

Apart from LR/Enfuse, applications that can do stacking/merging include recent versions of PS, PhotoAcute, and Photomatix. I am sure there are others as well but I don't know enough to tell you what the very best options might be.

One thing that might be worth mentioning here, apart from what has already been said, is that you can stack/merge for more than one reason. What we have been discussing here is stacking for the purpose of improving DR/SNR and minimizing noise. But you can also stack for the purpose of extending the sharp area of a photo (focus stacking). And you can of course combine these two if you want. In a recent exchange with kenw, we discussed the possibility of doing this for landscape photos where it is important to have the foreground as well as background tack sharp and where you would also like to maximize DR.

Photomatix will do "Exposure Fusion" which does a nice job of merging images for low noise. This is a different method then "Tone Mapping" which is the usual HDR mode.
