Shade % question.

[empiref]

To all the Orchid experts out there.
How do you rate the Shade in the pics?
60%, 80%, 100%?

Thanks.

It's hard enough to judge % shade by eye, and even harder to do it by eye from a photograph.

Seeing as you have a camera, with a piece of white paper you should be able to work out the foot-candles; I detail the technique in a blog post Orchids on a Balcony: New Gadget: Light Meter.

In brief, Using a piece of white paper, with the camera lens at a distance of about 30cm from the paper, at f2.8 with a film speed (ISO setting) of 200, the shutter speed is approximately equal to foot candles. If that sounds like too much maths to you, First Rays have a handy form you can fill in that works it out for you.

If you hunt around, you should be able to translate the FC reading into %shade.

It's hard to tell from the photograph. It's probably good for your phalaenopsis. Cattleyas may want a little more light. I can't guess the actual percentage you have.
