Hi there,

I’m an amateur photographer trying to achieve more consistent results from skin undertone tests using my smartphone camera, but I’m running into some annoying issues with lighting. For example, I took photos of my face in natural window light in the morning, then again under my bedroom’s warm incandescent bulb in the evening, and the perceived undertone changes completely! Sometimes my skin looks cool-toned, other times more warm or neutral, which obviously undermines any analysis I try to do.

I’ve tried adjusting exposure and white balance settings on the phone manually, but the variation under different light sources is still too erratic. It feels like the camera’s sensor alone can’t always be used safely without optimal lighting, which makes me wonder what kind of setup you all use for these tests. Is there a particular type of daylight simulation or color temperature I should go for? Or specific angles or distances from the light source that help the camera better reflect true skin tone?

I’ve found some photography lighting guides focused on skin tone testing and color accuracy, such as soft winter color palette , but I’m still curious about actionable, low-cost lighting hacks or setups that others might have come across. For instance, would using a ring light with a diffuser make a major difference, or is natural daylight near an indirect south-facing window still the best option? Has anyone worked with affordable LED panels or even DIY solutions like using a white foam board to reflect light?

Any examples or photos of your setups would be much appreciated. I’d love to hear from others who’ve managed to get more reliable, camera-based undertone results that don’t vary wildly based on the lighting environment.

Thanks in advance!
