There seems to be a reasonable number of RAW converters to choose from for Macs.
But for integrated RAW/DAM, it looks likes there are only Lightroom, Capture One Pro (and maybe Bridge) for the serious photographer.
Without any numbers to go by, I would guess that Lightroom is the hugely dominate solution. So dominate that there may be fears of its monopoly status.
I assume, then, that the folks using Iridient, RawTherapee, DxO, and the others are either working with Lightroom (still) or have found some other application to handle their DAM needs.
Overlooking the inconvenience of having large RAW, and TIFF/JPG, and possibly PSD, files to store and keep track of, what are others using for DAM? Are there real, solid, solutions for the serious photographer?
