I don't work with 2D, so take my suggestions with a grain of salt. There are many practical suggestions you can find online and through literature for taking specimen pictures. Barrel distortion is something you need to mindful, as most cellphone cameras often have a wide angle equivalent objective. Usually it is preferred to have farther working distance to the object but use a zoom or tele lens to minimize the distortion.
Working with a fixed height may give you more control over focus (choosing a depth of field that keeps everything in focus), but for those you probably need something like DSLR rather than a cellphone to have the maximum manual control. While the purpose (photogrammetry) is different, , this paper goes through a lot of those for taking many pictures of specimen in controlled settings https://academic.oup.com/iob/article/5/1/obad024/7221338 On Wednesday, February 11, 2026 at 6:21:41 PM UTC-8 Eduardo Henrique Janke wrote: > Yes, standardize is a better word. > > I'm starting my works with MG this year. > I will set my landmarks over penguin bones, so we're sketching a device to > take the photos, with a standardize height, a centered position for my > smartphone camera. > > What i want to know is if you have any suggestion, or idea to help me > build this device > > Em terça-feira, 10 de fevereiro de 2026 às 22:37:33 UTC-3, K.
