Photoshop....... I'm sure this is embarassingly obvious, but, when you're using the magnetic lasso tool, whats the best way to make stick to the edge of the photo? Say you want to select the top half of a picture, you use magnetic lasso on the edge between foreground and sky, but then you get to the edge of the picture, and want to select the top and sides of the photo, but the magnetic lasso keeps tying to pick up details in the picture? Any way to just make it do a straight line? I know this isn't makin much sense, but if anyone understands and knows a way round this, t'would be muchos appreciado. ta
