with P1[:-1] it's help avoid '-inf'# in crit. ImageJ Yen implementation replaces those values by zero.crit = np.log(((P1_sq[:-1] * P2_sq
Hi Elisa, it looks like you have a few issues in your code that might be causing the histogram not to be displayed properly. Here are some suggestions and corrections to help you plot the histogram of a series of tomography images effectively:
In short, although it is true that practicing the ETTR method correctly will give you the absolute best possible image quality, you can still creatively expose a scene with great success. SeeHigh-KeyandLow-Keyin our glossary for more examples!

Here are some concrete examples. You can have one very dark image: and its associated histogram: Notice how all the data is shifted far to the left, with almost nothing on the middle and the right side. Also notice that the headlamp beams are too small to be noticeable in the histogram...
