Since reinstalling the latest version of FIJI on my computer the B&C window seems to behave differently. To show you an example, here are two copies of the same image. One is untouched (‘Unadjusted’), and when I select the B&C window the minimum value is zero as I would expect. But when I drag the minimum bar up and back down again (as in the ‘Reverted’ copy of the image), the minimum value changes (in this case to 1449), and the slider cannot be returned to zero. This corresponds to a change in the image (dim pixels become black), and finer structures become invisible.
I am confused about why this is happening without me ever pressing the ‘apply’ button. The ‘reset’ button has no effect. The only way I have found to return the minimum value to zero (and restore all the visual information) is to manually set the minimum value to zero using the ‘set’ button, and then to repeatedly click the left arrow to return the minimum bar to zero (if I drag it with the mouse the minimum value jumps back to 1449). Obviously this is very annoying.
My ImageJ expertise is limited, so I may well be missing something! Hugely appreciate your suggestions.
Thanks for taking the time,
