From Peta Pixel:
I wasn’t carrying a stand-alone camera when I saw this woman but knew it was an image I wanted to capture. I asked if I could take her photograph and post it on my Instagram account because I never saw anyone applying makeup just like that on a train. She replied yes and continued fixing her makeup while I used my iPhone XR using existing light to take this photo on November 21, 2019. I asked if she wanted me to tag her. She replied yes and typed @cocaine_waiitress directly onto my post. I applied the hashtag #onlyinny.
