This was taken last summer on Pride Sunday, here in Toronto.
As I was leaving the Gay Village and returning to my car, I noticed an attractive young woman in an interesting costume, and asked her if I could take a couple of street portraits. We walked down a side street into a shaded area where I took two or three environmental shots with a 35, and then switched to my 105 to get a head and shoulders portrait to accentuate her beauty. As she posed she playfully brought her Mardi Gras mask up to her face and I got this shot.
