The reason why most of my photos look like this because I use my mobile android tablet(its also the device I use to make all my designs with) camera to make the photos and a small flashlight to make the lighting. Also I really don't have a really high quality camera and a high quality flashlight yet because the cameras are mostly expensive(some of them are like 65$ to 1,999$ in some cases) but I might get a high quality flashlight since some of them are pretty cheap from what I've seen. Also I use tape instead of glue because I kinda find glue messy and easy to mess designs up easily.
I said this because I've gotten these sayings about these every time.
Also if you're wondering about what software I use to make my papercraft designs with is called Sony Sketch. That's all I gotta say about that question
