Dry tropical zone, Princess of Wales Conservatory.

I really don't think IR is appropriate at all here. If the effect you were looking for was the white colour of the plants, perhaps you should have taken an isolated picture of a plant. also the roof is overexposed.

Yes I agree, including the roof led to a big area of white, over-exposure.

 

This was my first roll experimenting with the use of an Orange filter for IR film. Experience showed that the Orange filter often leads to over-exposure because so much visible light is let through as well as the IR.

 

The results would probably have been better with a Red filter but that would have required a tripod, which you are not allowed to use in some situations. I have some other Orange filtered shots which I should post for comparison.
