Confused about light

[stemper]

I'm brand new (almost) to orchids. I did grow a beautiful dendrobiu, of few years ago which reflowered a couple of times. I now live in a new house (Lot of windows, lot of light) and am trying some orchids. I managed to scorch a lady slipper, a dendrobium seems to be doing well, but the leaves of an unidentified plant are turning yellow. Does this mean too much light? I've been reading the postings here which are very informative but I'm totally confused about light. I always thought that orchids didn't like direct or strong light but now I'm reading that the opposite is true. I tried that with the Paph with not good results. Perhaps it was getting too much direct light?

Any info would be appreciated. Or pointers to a good orchid book or two.

Thanks.
