How Can I Calculate Lens Needed for Projection?

Postby Donnieclark » Sat Nov 11, 2017 4:14 am

hii,
I have an image that I want to project. The lens needs to be situated a foot away from the image and I want the image to be projected clearly on a wall about 10 ft. away. How can I calculate what type of lens or combination of lenses I need?I wasn't able to attach an image of a diagram, but I'll try again later.

Thanks!
I didn't find the right solution from the Internet.
