Thank you very much for your response but it is incorrect. I have the same problem as the original poster -- the standard Lightroom Presets, at least Cold Tone  +  others are not stackable. I used to get great effects for example with Cold Tone + Direct Positive on top of each other (and in that order) or Bleach Bypass + Direct Positive (and ordering, sequencing of the effects all generated different output) in previous versions of Lightroom. That's now all gone -- I've resorted to using previous (3) versions of Lightoom to retain this ability to stack effects. I am using both 3 and 4.3 side by side, only in 3 are the effects stacking on top and being applied as a blend. In 4.3 one cancels out the other. If anyone knows the answer for Versions 4.x would be much appreciated.

Thanks!

So that means that both of the opinions here are correct:

You just don't get the same additive effect (I prefer this term over *stacking* as this means something different in Library), because the process versions of LR3=PV2010 and LR4=PV2012 work different, hence the LR-shipped presets now do overlap.

Whenever presets overlap, the last one applied will win.

This leads to 2 pretty different strategies in creating your own user presets:

Either you think you can do "all-in-one"-presets and they fit more than the image you developed it for.

Or you think you have to add more individual effects, each one only affecting one develop panel, so you can combine these bits in many different ways, to suite a real broad range of images. Which means they are really additive.

Hi Jim Forbes,

This does create a PSD-file from the virtual copy?

And it bakes the previously first applied preset into the pixels?
