Hi Tom, I managed to check it while the light was out tonight. There is faint fragrance. But it is not a nice one. According to my wife (with a very sensitive nose), she can't quite find anything similar, but she detects a little bit of rose-like component, but it isn't the dominant fragrance. The rose could smell nice when it isn't strong, but when you are surrounded by too many roses, it isn't a pleasant smell (my granduncle used to be a professional rose grower, so we frequently got lots of left-over roses). And she is referring to this unpleasant component. I also can't describe it, but I feel that some animals could smell like this (no specific animal).
Thank you. White flowers are difficult for me. It is a pretty cheap "studio"-like setting with 8x high CRI LED flood light bulbs: https://orchidborealis.blogspot.com/2016/11/inexpensive-led-lighting-for.html I'm using a reflective umbrella (unlike the pass-through in the blog post) + Westcott 28" Softbox now.
