For most of my career, we shot black and white and good ol' ISO 400 Tri-X was my staple. And yeah, I pushed it to 3200 regularly (night sports)
But at my paper, when the T-Max 400 film was introduced, I pushed the living shti out of it to as high as 25,000. I used to mix the T-Max developer stronger than recommended. I was known as the prince of darkness. I could get usable inages at that film speed when others were using their strobe for light. My images always caught the emotion. Strobers? Not so much.
When we went to Macs and Photoshop, I still pushed the film enough to make it scream. This was in the day when we used scanners to get our images from the film to photoshop.
Shooting digital is like shooting chromes (slide film), you have to slightly underexpose it to truly get the full image. If you overexpose chromes or digital, it just washes out and in both cases, is unusable.
