is another tutorial that has come about by a request from the forum.
This is how you wrap something around a cylinder. This us useful for creating labels for cans etc.
Begin with a cylinder. or make your own with the gradient tool.
If you make your own, set the gradient to reflected and linear.
the object you want to wrap around the cylinder and put it on its own layer
Here is where it all happens:
Filter>Spherize set the amount to 100 and change the mode to horizontal only.
See how it looks distorted?
Press Ctrl/Cmd+T for free-transform.
Drag the sides in until it matches the size of the shape.
step will add a boost of realism.
Change the top layer to multiply mode. See how it appears to blend into the cylinder, and it shares the shadows and highlights.
If you want a more rounded look on the ends of the cylinder:
Make a huge selection with the circular marquee tool.
Invert the selection. Ctrl/Cmd+Shift+I
Now use the eraser tool to erase the corners away.
