Not sure if this should be here on on the iStock forum.
I was using the keyword 'variety' on an image I was uploading and one of the options was 'variety (filters)'.
It wasn't the DA I needed, but I was curious, so after I finished uploading, I did a search on variety (filters) and was none the wiser.

So I googled and all I found was:
http://www.bhphotovideo.com/c/product/74132-REG/Manfrotto_CI_FP209_Variety_Filter_Pack_12.html
Which I can hardly imagine is what was intended by that DA.
So, is it something of which I'm ignorant, or is it just a weird anomaly?
