Filter order filters filtertray mattebox By Philipp Uhl on 1/26/20, 2:14 PM • 292 views Hi! Do you have a standard order of filters in your Mattebox? I‘ve heard different „rules“ like ND first, then Diff, or vice versa, but when I did a bit of quick testing I couldn’t see any real difference in the image. For convenience I like to have diffusion filters nearest to the lens, because these are usually the ones that stay in there for the whole day, and then have ND in front of that. Do you have something else that works best for you? Or did anyone maybe find a difference in the image that changes with filter order?
ERIC UGLAND On 2/4/20, 1:09 AM I was trained to always keep the diffusion closest to the lens. Placing the diffusion further from the lens can, in theory, change the level of diffusion on the image. In practice I think it's difficult to see the difference, but I think it's important to have consistency. Always keep multiple filters in trays stacked, not with an empty tray in-between. Gaps easily cause reflections.
Chris Steel On 3/18/20, 3:53 PM Pretty much what everyone else has said. Lens, C. Pol, ND grad, Diffusion, FX, Colour, ND†, T. Pol, OpFlat †Heavy ND should be behind Light ND so any back reflections off of the light ND have to go through the heavy ND twice, keeping them minimal. There will still be back reflections off of the heavy ND but this will minimise the problem. Matte-boxes with tilt functions or tilt trays can help get rid of some reflections. (Vinces tip is also great, done that a few times. Little bit of tape stops any jiggling too) When using diopters, to get the "best" out of them I'll get them as close to the lens as possible then stack the the filters in-front. Generally I'd suggest dropping the Dif strength as the diopter will add it's own look. If the DP want's more exaggerated looks then adding the diopter way out front is interesting. Having it on an arm to get tilt effects etc. With old anamorphics, use the least strength needed to get the focus range needed. The 1/2 diopter is your friend. Rough cheat sheet, use as a guide for choosing a diopter. Measure from the Diopter, not the focal plane. Diopter strength 0.25 0.5 1 1.5 2 2.5 3 3.5 4 Max Focus (M) 4 2 1 0.7 0.5 0.4 0.3 0.27 0.2 Max Focus (Ft) 13’2 6’6” 3’3” 2’2” 1’6” 1’3” 13” 11” 9” Rozemarijn On 3/18/20, 4:37 PM Sweet! Never knew about this cheat sheet. Ive always guessed it :) Thanks Chris
This is based on the math and does differ from real life as the diopter can never be exactly on the front element of the lens. I mainly use this as part of a discussion about what filter to use and with which lens for the desired effect and flexibility. Rozemarijn On 1/26/20, 2:40 PM Hey Philipp, i actually do the same. Any dif. Filter close to the lens. Mostly its just the ND or Pola up here and if its just 1, always as close as possible to the lens. But im also curious what other people do!
Klim Jurevicius On 3/3/20, 4:17 PM Thats how I've been taught, it does makes sense to do it that way. 1.Look filter 2. ND 3. OF Vince On 1/26/20, 2:44 PM I do something similar. Only when the DP uses a rota pola, I place this one always as close to the lens as possible. Infront of that I put it the ND filters and any special filters. What I tend to do when having those really special filters, is keep a tray "empty" in between so I can remove the empty tray and tilt the filter when there are unwanted reflections or such.
