F5: F5/F55 4K shot through 2K OLPF

As the title suggests, this is what I've been testing.
I like it, a lot.
4K shot through the 2K filter is not intended use (2k OLPF is intended for HFR 2k to minimize aliasing etc) but I just love the effect it has on 4K shot leaving the 2k filter in. It's more organic, creamy and takes the "edge" off what can be too harsh 4k video.
It was a bit difficult to focus with it in at first, but I just left it in there and within a day, focus was bang on and easy as per usual.
Here's a frame from my F5 shot 4K RAW through the 2k OLPF, at night, using one diffused LED and natural street lights around.

whats your guys thoughts?

Can you link a 4K PNG or something?

Once it's resized down to less than 1920x1080, there's not a lot to tell from it.
 
I know the OLPF behind the lens is a much different effect than something which can be placed in front of the lens - but is that entirely true? Has anyone created creamy images either from a lens filter or some concoction in post?

I was able to do something quite similar around 10 years ago using some script based video processing software. I forget how I did it, but it looked like very celluloid-like.
 
For Any one interested, Here's a link to download the referenced still, as both Ungraded and Graded, in PNG and DPX (although its 4K UHD, not FUll 4K, as Resolve lite restricts to UHD, and yes, I tried the "render at source resolution, but came out with huge black borders)

Shot RAW 4K to R5 as 50P, 2000 ISO, 180 degree shutter, Nikon 17-55mm F2.8 (so not the sharpest still shot wide open, it is a bit soft and would have natural motion blur)
Processed/debayered through Resolve lite with Slog2/cinegamma3.cine baked in on export.

Hey Justin, thanks for indulging me!

I personally think it's pretty soft. That doesn't make it bad...just softer than I myself like, especially if people involved in the production were also hearing "we're shooting 4k"

I suspect, going forward into the 4K distribution era, there will be some times when a DP or director will have to decide whether real 4K resolution adds to the project or detracts. I, (like you, I suspect?), don't subscribe to the idea that seeing every little thing in the frame is conducive to good storytelling or communication. That means choices in both black levels/shadows and resolution. There seems to be a trend that now we have cameras that can resolve crazy detail and see deep into the shadows, you can wind up with a very busy frame and the eye may have too much to look at.

If I was going for what you shot, I personally would just shoot it 2K or 1080 with the same OLPF and call it a day....I don't think anything approaching 4K resolution is making it through in your still, but it's truly hard to tell...
 
I totally agree Nate.

You right to assume I don't subscribe to seeing it all in the frame (and the grade is a throw on impulz LUT)
but I shoot 4K (and clients here in South Adrica don't care about 4K, nor do they know what it means) purely to either stabilize my handheld tracking, or in my mind resolve in post the best I can by working in the higher space, only to down sample to HD in the end. As far as I can tell, images are sharper shooting 4k down sampled in post to HD. I never master in 4k anyway.

i know it's a bit soft, but I like it. And for HD it's fine, and I did mention a lot is in play to make it soft. 2K filter, f2.8, slowish shutter, motion blur of the singer, motion blur from myself walking backwards in shoulder mount mode, under exposed etc etc. But I love it! Maybe this isn't a good example of the 4K thru 2K filter, but I'll upload a better example soon.

All in all I just love what I'm getting from this combo, I leave the 2k filter in all the time.
 
I kind of like the look too, I wonder what the difference is like between shooting 2K with OLPF vs. 4K with OLPF then downscaling to HD?

Anyway I should know soon enough my OLPF is on order.

:grin:
 
I myself found the definition of crispy in two steps:

1-Got the R5, now can shoot 4K raw

2-Got Zeiss compact zooms.

I never thought I'd say it, but I inadvertently found/bought a combo that is going to be too sharp for some jobs. But that's ok, I know how to soften it up and I'd rather have the option.

BTW, I found the resize method from 4k to 1080p in Resolve makes the biggest difference for me..."Smoother" vs. "Sharper"

Using "Mist" in Resolve does nice things too.
