Photoshop Tip
Abstract:
Easy erasing.
Body:
A common use of Photoshop is to remove the
background from an image. If the image is to be composited with a different
background, then it's important to completely erase all of the background, or
un-erased areas may be visible when viewed on the new background's colors.
Finding these areas can be tough even if you change to a contrasting background
color, especially if the areas are only a pixel or two in size. Below is an
image that I've been working
with:
At first glance, it looks like the background is completely white, but I'm sure that I've missed a spot or two, especially since the original photo was taken against a white wall.
To find the edges of the layer (which has transparency), I turned on the Stroke layer effect.
I set a red stroke of 3 pixels, and look what I found:
With the stroke turned on, I simply went around with the eraser tool and got rid of all the red specks.
Hope this was useful. That'll be five bucks.
