In my experience, Lightroom makes for a significantly better and faster workflow for photographers than Photoshop. The early versions of Adobe Camera RAW were primitive and only recently has adjustment controls similar to LR. However, it's a single image workflow, right? I can't imagine how much time it would take me to go through a series of 2,000 bracketed images in Photoshop (the low end in numbers I'd capture in a week's travel). I do use Photoshop to do pano merges, masking and finite editing (things that can't be done in LR), but I can apply a color grade along with graduated, radial and custom brushes, transform, noise, sharpness, vignette, lens correction, etc. to hundreds of images and export as JPG's with only a few clicks from LR. All of the adjustments are non-destructive, saved as sidecar XML files, so if I need to adjust a single control, I can apply it to a hundred images in one click and re-export the whole batch. How would that workflow look in Photoshop?
