Howdy, new member and completely new to photography.
I built this wood box camera after seeing a video of a guy in Afghanistan using one so thought I`d give it a try.
I`ll post a walk around video of my camera and some pictures I`ve taken with it.
The lens is a magnifying glass that is about two inch in diam. it so far works the best for taking a negative and for taking a picture of the negative .
The issue I`m having with the magnifying glass is the image is clear in the center but gets blurry the further out ya go.
I bought some 135mm f4.5 lenses on ebay but they won`t give a big enough picture and I can`t slide the focus glass back far enough for taking a picture of the negative.
I feel like a real idiot asking but can someone give me some idea of a place to start with a lens, do I need something like a 300mm f-8 ?
Any help would be appreciated.
Paper size is 3 1/2 x5
