Hello,
This is something that might be useful for those projecting large format cameras or trying to figure the behaviour of a new combination lens/camera. So many times I took paper and pencil to undergo these calculations that I decided to do it once for all. I hope you will like it. Case you find any trouble, or have any suggestion for improvements, please get in touch. This is a sort of beta version. Cheers Wagner
