Log curves lift the lower and middle parts of dynamic range higher up where most of the bit depth is located so you have more shadow detail to play with without clipping highlights. When exposing S-Log2, the footage looks flat and washed out. Watching some grading tutorials, you’ll see that all log clips have the same milky desaturated appearance. It has not been overexposed so much as properly exposed. If underexposed, you’re losing the benefits of shooting log. I believe all log profiles work pretty much the same way.
