Hoping I can get advice on correcting an image in Photoshop ! I have no idea what caused the fault line in this negative, it hasn't seen the light of day since I took it in the late 1980s ! It is the only frame on the film that has the fault and I can only assume something was between the camera and my friend.
I only use Photoshop for basic corrections and have little experience of using layers which I suspect may be required here ... and I have no doubt to many in the forum, it will be a very simple straightforward fix ! Any advice on how to darken the bottom half of the image to match the top half and removing the dividing line, in simple terms, will be much appreciated !
Thanks in advance.
