Nick Hughes Posted August 9, 2015 Share Posted August 9, 2015 I prefer Aaron's original grade. Skin looks more natural to me. I also prefer a warm grade over a cool one, but that's purely personal. Quote Link to comment Share on other sites More sharing options...
Zak Forsman Posted August 9, 2015 Share Posted August 9, 2015 Yeah, that Alexa LUT does make for a nice look. It's little more contrasty than I'd like to go, personally. But an excellent starting point overall. Here's some more clips shot in the Natural profile (0, -5, -5, -2, 0) that I've applied my own custom LUT to.

AaronChicago Posted August 10, 2015 Author Share Posted August 10, 2015 I'm definitely a fan of your looks. I prefer (like yours) a more stylized less saturated grade for most projects. The main reason I was testing color with GH4 Portrait was to get something close to Canon C100 colors. Focusing on the girls hair was a good indicator of how realistic I could make the red channel. When I added the Alexa LUT it looked spot on with how it looked in real life. I don't know how or why but it just takes the GH4 color and turns it into a more realistic looking image. 90% of the time I wouldn't finish a video with a "100% realistic" color look, but there are times when I do and it's nice to have that option.

Guest Ebrahim Saadawi Posted August 10, 2015 Share Posted August 10, 2015 Wow that Alexa LUT makes ''the'' exact trick that's needed to fix the slight GH4 colour issue. Very nice. The skin of the girl is magically transformed from GH4 skin to pleasing skin. And the hair and greens. I wish my NLE (Vegas Pro) supported LUTs (Come on Sony, Vegas Pro 13 is a 2015 update of an industry professional NLE and no LUT support came to mind?!) It's such a shame as I wanted to try this on my footage. Now I need to research and pay for fiddly third party software to start using LUTs and pray they work. Nice catch Aaron. An enormous subtle difference! Quote Link to comment Share on other sites More sharing options...

kaylee Posted August 10, 2015 Share Posted August 10, 2015 what a coincidence: that very same alexa lut in premiere is doin some magic on my slog2 rx10ii footage shot w a modified version of kholi's pro color settings. i just randomly tried it playing around with lumetri. im looking for a baseline of pleasing, naturalistic color and what i described is working really well Zak Forsman 1 Quote Link to comment Share on other sites More sharing options...

But an excellent starting point overall. Here's some more clips shot in the Natural profile (0, -5, -5, -2, 0) that I've applied my own custom LUT to. 1. Those look great. Natural, understated colors, nice neutral highlights, and healthy skintones. Excellent work.2. You are a stunningly rugged man. Respect.3. Any chance you'd be willing to share your custom LUT? Or is that too much of a trade secret? Quote Link to comment Share on other sites More sharing options...
Guest Ebrahim Saadawi Posted August 10, 2015 Share Posted August 10, 2015 Vegas doesn't have LUT support? That's crazy!We've been telling Sony that for the past 5 years! Perhaps I'll buy Magic Bullet LUT buddy (in a package of other software that I absolutely don't want) which is said to be able to import Luts in Vegas so I could try these on my cold GH4 footage.

PannySVHS Posted August 10, 2015 Share Posted August 10, 2015 Aaron,looking sweet. Kinda fleshy and rich. One thing though as with a lot footage done in Cine D+LUTs: it seems in some shots there is some greyish tone in the skin color, very lightly though. Am I wrong? Other than that, looks like a Canon color parade. Or am I wrong on that one too?:) Thanks for the LUT. Gonna check it out.cheers, Marty AaronChicago 1 Quote Link to comment Share on other sites More sharing options...

Yeah there is still a tiny bit of grey cast, but enormously better looking than the regular profiles. It mixes really well with C100 footage (which was my goal). The key is riding a fine line with the hue slider and pushing toward magenta. Quote Link to comment Share on other sites More sharing options...
PannySVHS Posted August 10, 2015 Share Posted August 10, 2015 Hey again,maybe giving it a little bit more contrast on the shooting profile could get rid of the tiny amount of greyish cast?Picking -2 or -3 like it has been suggested a lot of times for shooting with the G6 on Natural profile. Did that and in Resolve picked an inputLUT like this one: http://juanmelara.com.au/downloads/video2log_lut.zip. Got it from this friendly fellow man: http://juanmelara.com.au/print-film-emulation-luts-for-downloadSo maybe in camera a little less flat and "flatening" via Input Lut in post, then your beautiful Arri LUT on top. Maybe that could cure the greyish cast? AaronChicago 1 Quote Link to comment Share on other sites More sharing options...

Maybe that could cure the greyish cast?it's worth a shot. The amount of contrast added by the Alexa LUT is nearly perfect for -5 in camera, but maybe shooting 0 and taking out a bit of contrast in post would work.

TheRenaissanceMan Posted August 10, 2015 Share Posted August 10, 2015 Here is the full video with the Arri Alexa SL LUT applied. My camera settings are under the description.Definitely a little flat in the skintones, luma-wise. It needs a little more contrast in post or the internal profile dropped to -2. Tests show that cranking the contrast lower than that just flattens the image without providing any extra DR. I don't know if people just don't test their cameras these days or what, but...Natural IS one of the normal profiles. Just because one of them has "Cine" in the name doesn't mean you have to use it. Natural for low-contrast and Standard for high-contrast have been my go-to GH3 profiles for years and provide excellent results in all kinds of shooting environments. All this "bad GH4 colors" and "lousy skintones" nonsense is 100% operator error. Glad to see people are finally digging into the camera properly.

AaronChicago Posted August 10, 2015 Author Share Posted August 10, 2015 Ok so I pushed up contrast what would normally make (I believe) up to a -2 in camera. Check them out: Before/After TheRenaissanceMan 1 Quote Link to comment Share on other sites More sharing options...
AaronChicago Posted August 10, 2015 Author Share Posted August 10, 2015 I went ahead and updated the orginal video. Added some contrast throughout the whole thing. Shooting at -2 in camera seems like it is the answer. Thanks TheRenaissanceMan 1 Quote Link to comment Share on other sites More sharing options...
AaronChicago Posted August 10, 2015 Author Share Posted August 10, 2015 Added Kodak 5205 Fuji 3510 (by Adobe) LUT on top to add some grit. Quote Link to comment Share on other sites More sharing options...
