I felt like artistically experimenting so I loaded some TriX 400 and went out on a sunny day to shoot it at ISO 1600. I went to a pretty nearby waterfall and took some shots. I then pushed it 2 stops in HC110 dilution B by doing 1.4 * 1.4 times the nominal development time.
In general increasing development 1.4x is equal to increasing the film speed by one stop.
Normally this is done to achieve better speeds in low light situations, but I found the effect it has on contrast and grain to be artistically pleasing for selected shots in bright light. It has a kind of vintage look to me.
