No, I zoomed in on a cd, that light pattern was showing on a cd laying on my dresser so I decided to shoot it. Used a 50mm 1.8 and got as close as I could, only cropped a small amount off edges to get the original starting image.
7D 50mm 1.8
2.0 sec; f/22; ISO 100
The end result was this first larger image in this post...which I made various crops of to get different patterns. I also made some circle thingys that I didn't really care for, images 2 and 3.
As you can see, with the final larger image...there are many possibilities for crops with something like that. I rent a room in a house and it's quite small...so I am limited and have to get creative sometimes to find things to shoot. lol
I'll just post 'em all. Feel free to crop up and play with it if you like.
