how to isolate an image and delete background

Post Reply New Topic

a long time ago, someone here made this for me:



I'm interested in learning how to isolate a feature in a picture so it can be used for other purposes using photoshop.

Also, I noticed that I can delete the background in a PNG image but not a JPG. If I were to highlight and hit delete anything on a jpg, it'll just turn white. But if I do that same thing on a PNG, I'll see gray and white squares which is good. That's what I want.

What you want to do is use the magnetic lasso tool. surround the shape (it doesn't have to be perfect you can touch it up later) once you have the entire flowerbaby surrounded by the lasso go ahead and connect both ends of the lasso toghether, and then copy and paste the picture of the baby onto a new PNG. There you can zoom in and use the eraser tool to touch-up the babyflower, put in your own background, whatever you want to do.

You could also:

duplicate the layer

Use magic wand to select the background (adjust the tolerance to cut as close the the image as you like)

then delete

add a new layer with black behind it to see how clean your image is or if you need to adjust tolerance more

when your satisfied delete the original locked image and colored layer

save as new png to keep transparency

This is my quick and dirty way cause I don't care to spend time cleaning up the image. If you want even crisper edges, use use the pen tool and make a path around the image.

I was more interested in knowing how he isolated the face to put it into the flower.

Thanks for your responses!
