Hi there, I'm a new mac user but have steadily began to get the hang of it. I recently downloaded the image editing software of Seashore. Currently I am trying to make a photo black and white apart from a certain part of it that I want to remain the original colour e.g. a black and white photo of someone but their lips remain pink. I have tried fiddling around with the different layers and erasing part of one layer (black and white) to let the other one come through (the colour layer) but have so far been unsuccessful. The problem seems to be that when I erase something from the top layer it doesn't go transparent so the bottom layer shines through, instead it just turns the deleted areas white. I have been to the seashore website but have find it very unhelpful. I have come to this forum many times and have always either found the answer I needed or, at the very least, been pointed in the right direction, so fingers crossed someone out there can help me. Thank you. Shayne.
