Mold n spike?

[drone]

There some kind of brown mold growing. Is it harmful? The plant looks ok, no side effects.



Are these oncidium spikes or somekind of thin wiry leaves? They have been there for months not doing anything. The older ones are dried at the tips, green below.



Third question, how does my camera make my orchids' leaves look so lush. The oncidium is actually quite yellow and sunburned.
