Today I have been learning about depth of focus. Here are the final two photos that I have created. 

About to go out now and scream!! :)))

My brain, she is fried!! 

Thank you for your patience while I document this learning so that I have some chance of remembering it!!! 

*following day... have updated the image to show the data so that I really can refer back to it... As Bom says, it is like Mirror, Signal, Manoeuvre!!!
