Well, OK, extract a rhino! We have a herd of rhinos on display around Southampton and took lots of photos at the weekend. Here's the first page of my album with one I extracted:
Choose the lasso and draw a rough shape around the object.
This was like using one of those contraptions where you move a ring along a bent wire without setting off the buzzer. It only has to be a very rough shape. Go to edit - cut, then File - new and open a new canvas with a transparent background. Click Edit - paste and your roughly shaped object will appear. Now use the eraser and start removing the bits you don't want. You can see here that I started under his chin...
Start with a large size brush and go all round then zoom in and use a smaller brush so you can work in fine detail. It really didn't take very long!
There's a website which tells you all about the Rhino project HERE. To see more photos, go to my album HERE. I've started the scrapbook HERE. We only got about half of them so more to come!
