Histogram

[Ryan Patch]

Can anyone tell me why my histogram looks like it's only sampling every few gradients?

It's not skipping samples or anything...it's telling you your image is comprised of very few "levels"

This is what happens when you dig an underexposed image out of the noise...it spreads what little data you have over the entire range that you have, and the process creates "holes". Notice how there's posterization on the wall on the left? The gaps in the histogram are that posterization.

In other words, you're seeing the exact result of creating something from nothing...

Apply a color/lut settings, make simple corrections, close the histogram window, move the time slider and open the histogram again.
Let me know if that worked.
