You need to maintain exposure control by varying the amount of light entering the camera

This makes it impossible to use the same 3mm thick frame as the smaller sizes

simply rotate the filter rather than switch it out

You are using daylight-balanced film and the light source is colder than the desired look and you need a specific amount of color correction to match your film's color balance (5500°K)

Hoya Variable Neutral Density Filter 1.5–9 Stops vari-ndx (nm) TH (%) x yDescription The Hoya Variable Neutral Density Filter provides a way to maintain exposure control by varying the amount of light entering the camera by 1. 5 to 9 stops (0. 45 to 2. 7 density for cinematic use). The precision built in double ring design allows the outer ring to rotate to control the amount of neutral density effect anywhere within the 1. 5 9 stop range. This double ring design is thin to reduce the likelihood of vignetting with wide
