Maybe using the tungsten film caused it to have a different look or response to color? Maybe because the phone and film are different on the Kelvin scale and the photos might be warmer or cooler than the other. That’s my guess. I really like 3/4. I love the monochromatic color scheme and the composition is really nice. I love 4 with the mix of warm and cool tones, I love how the lights are frame and the blue lights contrast it really nicely. Nice work.
