They're a total experiment. I have a +10 diopter that I got for my Holga and I held it in front of my Lubitel's bottom lens. The tricky part is guessing how far away you have to be from the subject for it to still be in focus. With the +10 diopter I was about 4 inches away. I haven't done any more lately because it can be time consuming to set up but the results are worth it. Thanks for looking!
I forgot to add, if you do Macro Holga it's the same process. Check out my blog...
