I installed a new water softener and then an RO filter in our home we bought two years ago using city well water, fairly high calcium content. As other have said, the reverse osmosis filter will give water quality almost as good as distilled but at much lower cost. For most, a water softener is also needed to condition the water for the RO filter as well as to soften water for laundry and bathing. The RO filter membrane will have a much shorter lifetime with calcium in the water. The water softener exchanges calcium ions for sodium chloride, which is easily handled by the RO filter.
I purchased the RO filter specifically for my photography hobby and also for drinking water. If in doubt on water quality, have it tested. Certain photographic processes will require fewer of certain contaminants, like calcium. This is particularly true for blue prints, vandykes, kalitypes, and other iron based printing processes.
