Two of my grandchildren celebrate their birthdays in March as well; it's a good month.
A shot of one of my granddaughter's classmates, taken at her birthday celebration, on Delta 3200. This is the first time I've used anything faster than ISO 400. Back in the day, if I needed to shoot in low light, I'd use Tri-X rated at 1600, in Acufine, which always worked well. I have a roll of TMAX P3200 in the refrigerator and will try that next time.
