Hi all,
I'm using colour threshold to try and isolate parts of an image and adjust brightness/contrast and i have one image where the area i'm interested in is thresholded red yet when i use the "select" option in the colour threshold window, the red area isn't completely bounded by the selection. In this image the selection runs around part of the left image frame, the whole of the top horizontal edge and some of the right vertical image edge and its the right side of the image edge that isn't selected for some reason so when i try to adjust brightness/contrast it still adjusts the whole image.
Does anyone know why the thresholded area is not completely enclosed by the selection?
Many thanks,
Matt
