Just to clarify, Lightroom would simply initiate these services that are then executed in Photoshop. So this would be just like initiating "Merge to Panorama in Photoshop" from LR's "Photo>Edit In..." menu.
Naturally I asked Russell about doing this first but he suggested I mention it here.
Sorry Scott - I don't mean to sound like a smart a$$, I'm just not clear what would be involved in this, and why Russell doesn't just make a plugin for it.
Could a plugin do this? e.g. like Lr/Enfuse & onOne's PerfectLayers.........
How is what you're asking for different than what the LR/ACR HDR operator does, now?
The HDR operator aligns, stacks and blends multiple exposures, already.
It seems to me the only difference is that the HDR operator requires different EVs for each photo and errors out if they aren't different, so if that condition were relaxed then it'd be very similar to what Stack-A-Matic does, with the added benefit that the data is in "32-bit" raw format.
Or do you take advantage of the other blending modes in PS's Layer-Stack item, so the HDR function would need additional blending modes, and maybe not be HDR, anymore.
Or is your thought that Layers and Automation be added to Lightroom and it turn into Photoshop but without paying for PS?
My thought here is that Adobe could create an API so that we could add additional items to the Photo>EditIn... menu. They did this for Bridge years ago but have not done so to Lightroom. If you install Dr. Browne's Services you'll notice that it adds useful items (Stack-A-Matic) to this menu in Bridge but not to Lightroom because, they haven't opened up the API to do so. Again to do so in one app but not the other seems shortsighted.
Night Photography and image stacking are being hugely popular and people would love to be able to initiate Stack-A-Matic from within Lightroom.
