Fujifilm X T3 F Log High Contrast ProRes Ninja Flame – RW test

A VERY short Fujifilm XT-3 real-world contrast test.

I shot a few contrast-rich scenes with contrast ratios exceeding 10 stops in some occasions, to test the F-Log and sensor performance.

Very harsh, very bright directional light at 12:00 noon.

Exposed-to-the-right, trying to balance between retaining shadow detail and not blowing out the HLs too much.

Lens: Fuji 50mm F2 + B&W Polarizer filter
Recorded in Prores-HQ 10 bit 4:2:2 on the Ninja V
X-T3 settings used: DCI 4K, HDMI output, Boost mode, Sharpness and Noise Reduction dialed down, No temporal noise reduction, No peripheral light correction, F-log.

Edited and cropped to 2:1 aspect; no scaling. Minor color correction, only blacks, mids and highlights adjusted.

The X-T3 held out great! Watch the fine detail and the shadow detail. It’s phenomenal – our Panasonic GH5-S is no match for this camera; the Fuji it blows it out of the water!

The Ninja-V was NOT behaving as expected; it still needs some special treatment when used with the Fuji X-T3. E.g: if you end a recording via the camera, the Ninja will flash black and the kangaroo icon appears; after that, most of the time, the Ninja will stutter and you will have to remove and plugin the HDMI. Nothing that a firmware update can’t fix i guess.

The X-T3 performed as expected, only…. i have two stuck pixels that are very dim and only visible in the shadows. It is no big deal; these pixels are so small. You have to know where they are, and disappear if you lower the blacks on the F-Log image. This is a €1.450 camera, so no complaints here!

GH2 HDMI output recorded with Atomos NINJA

Ninja Graffiti by Martin Beek / http://www.marvelsfilm.com

Recorded at the annual Graffiti event in downtown Eindhoven (The Netherlands) using the Panasonic GH2 and Atomos Ninja digital recorder. The Ninja is a GREAT sub-1000 euro ProRes422(HQ) HDMI recorder from http://www.atomos.com .

I’ve used the GH2’s Smooth picture profile (all settings on -2 except for color saturation at -1) and Voigtlander Nokton 25mm/f0.95 lens with Fader ND filter. Aperture fixed at f2.8. Mixed 160 and 320 ISO.

Quality of the footage is stunning; it’s a pity that i had to convert it to H.264 to upload to YouTube, plus the extra compression crap that is added during YouTube’s conversion.

You can download the original hires/hi-Q input file (H.264, not the FCP ProRes444) from the Vimeo page at : http://vimeo.com/user6312268/gh2cleanhdmininja

Music: “Yeah Yeah” by “Bodyrox featuring Luciana”. Buy the music here: http://itunes.apple.com/us/album/yeah-yeah/id211458233

HDMI Ninja-recorder footage was deinterlaced, decrippled and converted to uncompressed 4:2:2 “fcp-ready” footage by using the free AviSynth and FFMpeg tools as described here: http://www.dvxuser.com/V6/showthread.php?237584-HDMI-Capture-Problem-SOLVED-AviSynth-RULES! and here: https://marvelsfilm.wordpress.com/2011/04/27/gh2-hdmi-recording-avisynth-script-update/

Cheers!

High ISO Noise Reduction on Canon DSLR cameras explained

High ISO Noise Reduction is a new feature that’s appeared on recent EOS Digital SLRs.  As of early 2009, it’s a Custom Function choice in the EOS Rebel XS.

The new High ISO Noise Reduction feature gives a further option for users of recent EOS cameras to improve the quality of their images.

It has a noticeable impact on the level of visible noise in shots taken at higher ISO levels, and can even have a positive effect on an image at lower ISOs (if it’s subsequently lightened using image-editing software).  Especially if you shoot JPEG images (MB: and video), we strongly recommend trying the different settings to see the effect it will have on your images.  For RAW shooters, it can also make a noticeable difference in how Canon’s software processes your images — although with Digital Photo Professional software, you’re free to independently adjust chrominance and luminance noise reduction beyond the initial in-camera settings.  More than ever, today’s digital SLRs are capable of excellent pictures at ISOs that were unthinkable just a few years ago.

With Canon’s most recent digital SLRs, the High ISO Noise Reduction technology is an important reason why.
