Robert Collins Posted August 20, 2018 Share Posted August 20, 2018 8 minutes ago, jonpais said: I shared my latest video and some screengrabs with a filmmaker friend who shoots with the GH5s, asking for his opinion about the tonal transitions, color, noise, detail and highlight roll off. I did not ask him to evaluate nonsense like ISO 100,000, or any other such pointless rubbish cluttering the Internet. He said the shots felt like they needed some shadow adjustment, not the extreme shadows, but around the 20-25% luma mark or so; that colour felt a bit magenta overall; and that noise and detail looked good, as did highlight rolloff. In other words, his evaluation of the image quality aligned perfectly with my own. He guessed I was using the HLG profile, perhaps because he knows that’s what I shoot on the GH5, perhaps because the results looked so good - I’m can’t be sure. Anyhow, that’s coming from a person known for being extremely finnicky about image quality. And he was evaluating images straight out of the camera, with no adjustment in post aside from dragging down the shadow wheel! Discussions about the film look are a rabbit hole. In many ways, the sensor in the a7 III itself outperforms that of many cinema cameras out on the market today, and the meagre 8-bit files look much better than some more robust ones - one downside being that they can’t withstand extreme grading. The point being, the a7 III would make a great camera for budget filmmaking or as a B camera - just as filmmakers have been doing with earlier a7* cameras for years. Have you tried HLG on the Sony A7iii? Just wondering. You mostly use Cine4 right? I used to use Cine4 but ?I find it can be problematic with highlights (in terms of easy to blow and hard to reclaim in post (although it does amount to user error.)

Unlike the GH5, which I try to shoot to the right, the Sony seems to do best protecting those highlights, at least in the profile I’m currently using.

Cinegain Posted August 21, 2018 Share Posted August 21, 2018 I'm calling FAKE NEWS!1!! He only got one so he has content for his next video: 'Why I'm returning the A7III and getting another Canon!'. ? Quote Link to comment Share on other sites More sharing options...

So you're saying that if he returns it after making another clickbait video then the purchase will have ceased to exist? We should use fake news to severely re-write history.... imagine all the people we could save from natural disasters, genocide, etc.. Slightly more seriously, I didn't see anything where he says he's switching, and I do remember him saying he's not definitely switching, so even if he returns it I'm pretty sure no promises will have been broken. Unless brand loyalty means you can't even look at a different manufacturer when an interesting model walks past you in the shopping centre and you turn your head to look without thinking and then get evil stares from your other half. Umm.. what were we talking about again? Quote Link to comment Share on other sites More sharing options...

Pretty please, could you summarize his thoughts, @Mark Romero 2 ? I could only watch up to 19 min. without losing interest. Who in their right mind thinks the a7 III has 15 stops of dynamic range? ?

Basically, lots of color fringing, bad skin tones, bad highlight rolloff, and noise. He said that the best way to salvage the footage was to crush the blacks (helps with color fringing and shifts), but that reduces the DR. Is it just because he is using a blue light in the background and we know the issues that Sony cameras have with blue light??? I will say in the samples he posted the hihglight rollofff looks a lot better than it does on my a6500. Yeah, I don't know who expected 15 stops of DR. And he is comparing the a7 III to a $20K Red Helium (as well as a $6K 1 DX II) noone 1 Quote Link to comment Share on other sites More sharing options...

webrunner5 Posted August 22, 2018 Share Posted August 22, 2018 A Red user complaining that cameras don't have as much DR as they claim! Christ Red is the biggest Bull Shitter in the business for what DR they have. Get real. All that guy does from the videos I have seen from him is try to justify all the money he spent on a Red camera. noone 1 Quote Link to comment Share on other sites More sharing options...

Yeah, I like your footage. It is looking good. I like the video you did with the magenta corrections. If you have a chance though to play around, could you maybe try shooting in Neutral (or Portrait) creative style with the picture profiles off, and then just reduce saturation and contrast (and sharpness) to something like -2, -2, -2 ???

And perhaps burn a hundred candles in my room to test the overheating, throw a hideously oversaturated blue light on the wall behind me just to offend good taste, and rent an Arri to prove I’m no noob? ?

Dave Maze Posted August 23, 2018 Share Posted August 23, 2018 Im so confused by HLG. Is it just applying a non destructive LUT on a log file that you can directly manipulate in post or something? Quote Link to comment Share on other sites More sharing options...
jonpais Posted August 23, 2018 Share Posted August 23, 2018 HLG uses a log curve for the upper half of the signal values, increasing dynamic range. Quote Link to comment Share on other sites More sharing options...
