In my work (lab research), I have need to take digital photos of thin transparent gels sitting on and being illuminated by a white light box. When I try to take a digital photo, weird orange bands appear in the image. These orange bands are not visible to the naked eye, but they appear in digital images taken using both Samsung and Apple smartphones. We know nothing about photography, so all our images have been made using the phones' default camera settings. To get rid of these orange bands, do I need to change some setting on the camera? Would some kind of filter get rid of these (even though, again, they aren't visible to the eye)? Any suggestions would be most welcome, because we are at a loss about what to do.
Your problem may be caused by flickering of the light source. Many people have problems with fluorescent lights in particular. This is similar to attempting to photograph a television because the bands and flickering are limited to the light box.
Light and dark bands appear when the shutter speed is faster than the flickering of the light source. You can try a slower shutter speed, like 1/40s. If that fixes the problem, you can increase the shutter speed until just before the bands reappear.
