Although I would suggest not manipulating what we were learning... (sorry don't know how to explain it) - ie. for the composition lesson, don't crop your photo on the computer too much if you can help it, because the aim of the lesson was to learn how to compose good photographs in camera.
And there is an assignment where you have to 'pan' your camera on a moving object resulting in a blurred background from movement - don't take a sharp image and then whack it into photoshop and give the background a motion blur
That's just so when we show our images, we are showing the result of the lesson, iykwim?
But it's really up to you!
