David, I put my gingers on the patio. They get full sun until noon and then pass into the bright shade of a tree. I do have them grouped together, so they kind of shelter each other. I often burn foliage in the spring when they first go out, but ignore it and leave them there. I just don't have the patience to move them slowly into brighter light since I have so many pots to move. The shoots on the plants in the spring when they first go out may not make it anyway. Sometimes they are weak from being inside. They are quickly replaced with new sturdy shoots. New shoots acclimate as they emerge and are adaptable to quite a range of exposure.
I have done better with my gingers since I started growing them 'hard and fast' since I only have May through September to grow them well. I put them out in the yard in May and fertilize them well every couple of weeks and I water mine daily during warm weather. They grow fast and send up several series of shoots that bloom in succession. The speed of repeat. depends on the variety, of course. I don't find any benefit from babying the first shoots that go outside since they are so quickly replaced with newer, fatter shoots that will bear the blooms. They have a growth habit like Cannas, though they don't like quite as much sun. If you push them, they will repeat quicker and keep blooming until frost.
One year I had a huge pot of Anne Bishop that I kept ignoring and not moving to its permanent location. It was in full sun except for the first two hours of the day. The weak, winter shoots burned up quickly and some really fat ones came up. I watered it daily and left it there all season. The plant got acclimated to the sun and had healthy growth and bloomed at three feet tall on every shoot, which was neat. I haven't repeated that, though.
You may not want to grow them like I do, but I find the more sun, water, and fertilizer, up to a point, the better mine do. I will say that greenii and rubrum definitely like less sun than other varieties, so watch your exposure if you get them. Also, if you use a peat-based potting mix like Miracle Gro, don't overwater in the winter or you may have problems with rot. Been there, done that. I get used to watering freely in the summer and you need to cut back in low temps.
Good luck!
