Filter Density and Format Size (2 replies and 4 comments)
I am trying to do as much as I can to match a look between formats. One format is anamorphic S35 and the other is slightly larger than 15-perf IMAX (76mm x 56mm). If I'm using a 1/8 Black Pro Mist filter on the anamorphic S35 format, should I use a denser filter for the IMAX+ format?
Thank you in advance
But why are you shooting in IMAX and trying to soften it down to look like 35mm anamorphic or Super-35? And are you talking about film formats where grain size / enlargement is also an issue? Are you blowing-up the 35mm to IMAX or shrinking the IMAX down to 35mm? How are you doing the post to be able to intercut the formats? Digital intermediate? Optical printing?
Thank you for your response, David. Those are great questions.
I am trying to match 6x8 medium format still photographs shot on spherical lenses with the anamorphic S35 aesthetic. I need the resolution increase for the still photo work because (in my opinion) grain is much more apparent in a still photograph than in motion picture film. The film will be scanned and presented digitally, film is only used for capture.
I understand that I will not be able to recreate the anamorphic character (cylindrical distortion, oval bokeh, unique flares) with spherical lenses, but I want to match the intensity of the filtration. Since 6x8 is so much larger than S35 (3.05x wider, 5.77 times larger area (6:5 S35 to masked 2.39 6x8)), I wanted to know if special effects filters had to be denser to match the 6x8 to the S35.
I wouldn't use heavier diffusion, then the artifacts are larger which might not match (larger halation areas, etc.) I'd match the filtration and then find ways in post to match better -- believe me, making an image softer in post is the easiest thing in the world! It's the other way that is hard.
Would you recommend that I just apply the entire BPM filter effect in post so the software has the most accurate information to work with when applying its blur algorithm or should I use a BPM filter to make the effect feel more organic?
You should do whatever gives you the look you want. If the BPM filter gives you the look you want, then why not use it?
I will. Thank you for your time and sharing your experience
