I tried comparing a few fabric colors against my face, but the photos from my phone are not consistent. Under the kitchen light my skin looks much warmer than it does in daylight. I cannot confidently decide whether a cream or a clear white fabric is actually more flattering. I have read a little about
skin tone analysis and would like to use a fair setup before drawing conclusions. I could stand beside a bright window and take both photos in the same spot, at the same time, with the same camera settings. Is it enough to lock exposure on the phone, or would that make the comparison more complicated than it needs to be? I also wonder whether a plain background matters as much as the light falling on the face. I want to compare the fabric rather than the camera's processing. If you have a simple routine for this, what would you control first, and what signs would make you retake the pictures?
