hi this is the image in question. some parts of it are fading off soft of. and im really new to photoshop. i have no idea how i can effectively remove the background of this logo. please help. thanks!
Ideally for such simple shapes one would recreate this artwork in a vector application, such as Adobe Illustrator. It's not that complex. However if you must use Photoshop and must not redraw anything.....
- Open the Channels Panel if it isn't already open (Window > Channels)
- Drag the Blue channel to the
New Channelicon at the bottom of the panel to copy it
- Highlight the Blue Channel Copy and choose
Image > Adjustments > Levels
- Move the left and right triangles inward to the edge of the histogram and click OK
This will darken the channel and increase it's overall contrast. So the solid areas become black
- Hold down the Command/Ctrl key and click the thumbnail for the Blue Channel Copy.
This will create a selection (marching ants) based on the channel.
- Move the Layers Panel (with the selection active)
- Hold down the Option/Alt key and click the
Add Maskicon at the bottom of the Layers Panel
This will add a layer mask to the layer and make the white transparent
If you need to further refine things, you can use Levels or Curves on the mask you just created.
Just in this case the actual shape is totally mixed partially to the white background. I guess this tries to be "an impossible geometry B" so it is a solid piece, it only has too bright highlight.
I tried to guess the intended shape and drew the missing piece of the edge. It's made with the pen and it has got a stroke:
After inserting the missing edge the shape (not the black edge) is selected with the quick selection tool and copied to a new layer:
After some practicing one can draw with the pen the whole clipping path, convert it to a selection and get substantially more accurate background removal result than with color and contrast based methods.
