These are very pretty orchids. Wonderful job at taking pictures of them too. I always have a problem with sizing. I have to turn my digi cameral all the way up to get the resolution, then resize it later, I want to think it gives me a better picture, but I'm not sure.
Welcome to the forum, I'm sure that someone will be able to answer any of your questions. If in doubt ask, though you look like a seasoned veteran to orchid care.
