My pictures of churches are all made with available light.
Some churches are rather dark, even on sunny days.
You often need a tripod, patience and time. High ISO doesn´t help.
You loose sharpness and depth in the colors.
This Picture was made handheld, leaned against a wall.
Sunlight coming slightly from above into the church at late afternoon.
I waited until the light hit the two sculptures.
Processing only SIGMA SPP 2.5 from RAW to Jpeg, no further processing!
