Allow me to set the scene: it's the first official lunch date with a lovely girl. She's keen on photography and wants to learn more, so off we go for a stroll through the city, and I show her my favourite haunts and scenes. All along I'm taking photos of her laughing, smiling, and playfully shooting back at me. All goes well, and I drop her at the train station as we both have things to do later that day.
At home, I upload my raws and start to check through them. But something is amiss. Everything looks super grainy and desaturated, like I've been shooting ISO 1600 film into the sun or something. But it's not, it's digital. Somehow I've set the camera on ISO 12,800 for most of the day.
