It is very interesting to see a bit of barrel distortion even on a pinhole, quite evident in your last photo showing the columns. I am now using cheap daiso 3X glass magnifying lens for my camera obscura project, but I'll be using my digital camera to take a photo of the projected image instead.

@@AnaloguePT Hi! I'm now experimenting with several focus plane materials. The first material I used has too much fibers on the surface, the next material I used is a clouded acrylic sheet, but the 3 mm thick acrylic flared the images too much until I can't see the details. I just ordered some diffuser paper/film, hopefully I'll get better results with that. I'll email you what I have done so far.

Thank you for yr photo. It is a sliding camera design. I also used a 3mm frosted acrylic as ground glass. Did U use a darkcloth ? It will block the reflections coming from yr back and give U a better image. U can also add a fresnel lens (those magnifying reading sheets) to make the image more even..have fun!

@@AnaloguePT Yes I did use the flat fresnel sheet to even out the magnification and brightness. Now waiting for the diffuser paper/film to arrive and replace the screen. Hopefully the image will improve.
