  • @kronstadt Maybe you should re-read. You said (or implied) something I disagreed with but it was not that. Basically nothing in the section I quoted from you was accurate, but it wasn't that.

    I tried to explain in detail why I thought so but I guess I should have just said, "no."

  • @BurnetRhoades what a nonsense... I never said Roger Deakins was the first one, and of course there were many cinematographers long before him.

  • @kronstadt

    "Roger Deakins are switching to Alexa is for purely budgetary reasons - higher ISO than anything that film stock can deliver, is a major saving when it comes to large sets with complex lighting setup, lots of lights, grip people etc. So the industry is less concerned with the"pale" look of Alexa and Red, and more with how much money and time can a given camera save during the production."

    Roger Deakins wasn't an early adopter of digital, he waited until Digital IP technology was such that it made sense to start using digital technology to craft the look of his photography. The first feature to ever get an end-to-end digital IP was one of his. It would be a mistake to assign budgetary reasons for any his decisions or attribute the results to your inaccurate dismissal of both Alexa and RED.

    Some DPs play in the shadows and grade everything so that much of the image plays out in subtle, almost imperceptible gradations of darker tones. Deakins has shown a tendency to do the opposite and grade to a very bright image with more subtle tones up in the highs. It's not how I necessarily prefer my imagery but it's intentional.

    Alexa and RED footage, finished footage, only looks pale if you grade them to look that way (or don't grade them, like most early RED films). This is a common issue with high-end digital cameras, complicated on-set grading that intimidates directors and accounts for radically different results using the same technology based on the expertise, comfort level and choices of the filmmaker. That's why you would never guess that Michael Mann used the same camera for Collateral or Miami Vice that David Fincher used for Zodiac or any part of Benjamin Button. And who could predict that any CineAlta could look so bad as Mann's Public Enemies???

  • @kronstadt @Aria

    Please, check topic title from time to time, it is about GHx, not about BMC, you can always discuss BMC, in proper topic.

  • I believe the GH1 is about 8 stops. I think you really have to finesse the intake of light so you can hide the fact that it doesn't have great DR.

    As for the BMC's pixel grain, I would have to disagree. I feel the look of BMC footage is very film like. Especially when talking about it's RAW output. I'm not sure what footage you may be referencing, but everything i've seen has proven to me that if you know what you're doing you can get absolutely glorious footage from a BMC. I could only wish that my GH1 could get that kind of overall look. I don't currently have the budget for a BMC workflow, but I do believe it could give me the kind of look i'm after.

  • @endotoxic

    Why i make this thread? Cos no ones has discussed this 3 cameras in not only technical view, but on a final result as an image from sensor codec lens.

    The only way to answer that question would be to arrange for something like one of those Zacuto shootouts which would use Kodak and Fuji film stock as the base and shoot the same scenes with hacked GH13, hacked GH2, GH3 and I would also like to see BMC and Alexa in such a test. Unfortunately, such a test does not exist. The closest to such a test was Zacuto's Shootout 2010 with unhacked GH1, and I just liked the texture of GH1 so much that I ended up buying it. As I mentioned, I e-mailed Zacuto 2 days ago asking them to include hacked GH1 in their 2013 shootout and to compare it to film stock. You can e-mail them too , to add more weight...

    There are of course die-hard film stock shooters like Wally Pfister. But it seems to me that the reason why cinematographers like Roger Deakins are switching to Alexa is for purely budgetary reasons - higher ISO than anything that film stock can deliver, is a major saving when it comes to large sets with complex lighting setup, lots of lights, grip people etc. So the industry is less concerned with the"pale" look of Alexa and Red, and more with how much money and time can a given camera save during the production. And Zacuto shootouts are increasingly adopting that flavour, rather than the question of which one looks more filmic.

  • @RRRR ,@Aria , @endotoxic if by DR you mean the Dynamic Range, then I'd say it is THE most important factor that separates Film from Digital. Film has roughly 16 usable stops. It shows Black as "more black" than what our eye is used to under normal situations -- that's why Film is a "hyperreal" medium. The other factors are As @Aria mentioned, smooth gradation and color. To that list I would also add the grain texture - Dots vs Pixels. So achieving a filmic look is really a matter of striking the correct balance between all these factors in a way that would best emulate the filmlook. If BMC, for example, with its 13 stops DR and 4:4:4 colour-space had a lower sensitivity (or a setting to deliberately lower the sensitivity) combined with a nice codec that would replace it's pixel grain with more filmic dot-grain and smooth gradation, then we'd have a very film-like footage. But BMC in ProRes 4:4:4 is not up to par as far as I'm concerned, so then it becomes a matter of shooting in RAW and adding these effects in post, which means more resources, more time, more specialists etc. GH13 somehow delivers not so high quality, but acceptable to most audiences, near-filmic footage almost straight out of the box.

    Correct me if I'm wrong, but GH13 has only 8 or 9 stops of usable DR. Am I correct? Maybe not even that.

  • @aria

    agree on this :

    For this kind of scenario, great DR, when it comes to film making is not so important. It can be useful, of course - but we can choose from lighting the interior to lessen the contrast or choose to let the highlights blow or crush the interior (if we´re looking out). These are context-based decisions to make.. but a lot of people avoid making any decisions simply because they have huge DR. (goes the same for post-work as for acquisition)>

    this apply if you are shooting only narrative, since DR is important say...documentary. damm even HFR 4k

  • @Aria I understand well where you are coming from.. and if you want the most eye-like-natural looking image (without working a lot on lighting) then yes, DR is very important. However, when talking about how we see things, it works a bit the same with DR as with focus. If we sit inside and talk to someone who sits next to a window and we pay no attention to the outside; we see the window mostly as certain intensities of light in the periphery. We focus on the person we are talking to.

    For this kind of scenario, great DR, when it comes to film making is not so important. It can be useful, of course - but we can choose from lighting the interior to lessen the contrast or choose to let the highlights blow or crush the interior (if we´re looking out). These are context-based decisions to make.. but a lot of people avoid making any decisions simply because they have huge DR. (goes the same for post-work as for acquisition)

    However, there are situations when the light is so peculiar and beautiful in itself where we cannot record it´s "face value" by any of the methods described above. F.i. when we´re inside a relatively dense foliage in the sun, where you both have light trickling down, "holes" in the foliage where we are used to seeing the sky and our eyes are adjusted to the light conditions below the trees. Now, to shoot something like that with limited DR range we´d have to do it in the morning (when the sunlight hasn´t peaked / is at an angle) and there might be a bit of fog dispersion in the air which acts as a diffuser.. But it might still get too dark underneath the foliage / too bright for any sky to show so that is really a situation where it´s very difficult to replace dynamic range.. the tools available to combat such situations are filters, and flags. For me, if I´m shooting a film in broad summer daylight / exterior and the budget allowed for it; I´ll go for a rented camera simply because it´s easier to handle harsh lighting and differences in light intensities. There will still be work to do with filters and flags, but I´d be more certain that the footage can be matched up afterwards.

    I can often affect when to shoot what and avoid some of the problems. But then again I live in a part of the world with pretty great lighting conditions for shooting outdoors.

  • @Ian_T, I think I somewhat understand what you mean. For me it's a combination of factors. There is a lack of HARSHNESS to FIlm. It's an organic type of detail as opposed to looking like it's been sharpened or the detail has an unnatural look to it.

    The next things are DR, Smooth Gradation and Color. An image that has too much contrast can look really bad to me. As I went thru the different picture profiles of the GH1 I found Smooth to offer the lower contrast image and best shadow detail. When I combine that with lower contrast Manual lenses it really helps even more to help the GH1 to get a more natural look that I like.

    Now artistically I may want more vibrant punchy looks. Say if I'm doing a music video or one of the TV shows I do locally. But then i'm not looking for the Film look. I trying to get good "Video" quality. Usually I light the scene WAY more than I would for a very natural look.

    @RRRR, For me great DR is HUGE. I can't get enough of it, cuz when I look with my eyes and see well into the shadows and my eyes don't blow out sunny windows and curtains, so when I see an image that gets closer to how my eye sees then i'm happy. Then from there I can tweak the image to taste if I want to change the mood a bit or be more artistic with it. I just don't want it coming off the sensor already baked in.

  • Well…ya’ll can take anything I say here with a grain of salt but what it comes down to for me…is the lower the HD resolution…the more filmic (not cinematic) it looks. I first noticed this with the HVX line of cameras. They were a lower resolution HD camera (I know….sort of an oxymoron) but they always had a more film like texture to it than all other HD cameras. That could be what some people are seeing with the GH-1. Personally I don’t see much of a difference between the GH-1 and GH-2 other than maybe sharpness (or rather detail). The driving factor, at least for me, between all of the GH-X cameras comes down to……..lens choice.

    Another example of what I’m saying above is the difference between Alexa footage and Red. The Alexa, in my eyes, always wins when it comes to mimicking a film-like texture. Not saying that it’s a better looking image but just stressing the fact that Red’s strength is in its high resolution while the Alexa is nowhere near Reds resolution but yet it’s “texture” can be a bit more like film.

  • @kronstadt @RRR @Aria @shian.

    Whay i make this thread?

    Cos no ones has discussed this 3 cameras in not only technical view, but on a final result as an image from sensor codec lens.

    This 3 cameras as being made, drop very diferent results and can be used as a set of tools. Canon cant make that, all their Ti series, al its D series have the same look, same color same all almost all. Panasonic i dont kwno if it was their searching for the better or just to try new flavor, but GH series is diferent, and each one has its own personality, not like APS-C over used canon sensor. MHO

  • @kronstadt

    The usage of "cinematic" as a buzz word is promoting stupidity / obscures clear defenitions. It´s far better to talk in terms of "I think, I like or In my opinion.." preferences of different kind of images than to try and make a one clear definition of the cinematic/filmic image (all such attempts hitherto has failed quite miserably and only succeeded in terms being swung all the more recklessly without any real thought put into it). In my opinion, this is all the more important since there are so many popular "sources" around that simply promote stupidity.

    I can fully subscribe to the idea of describing different camera outputs sort of as different film stocks.. Although it doesn´t paint the whole picture since they behave rather differently. What is cinematic / filmic and what isn´t? We all have different opinions on what´s nice and what isn´t and preference for certain characteristics over others. Many on them depend on how we process the footage and for some (me) it also depends on the project.

    For me, the gh1 can succeed very well in emulating s16mm film stock.. The gh2 on the other hand is a bit more in-between and can emulate both s35 and s16. It´s one of the choices I like to have with it.

    @aria I get what you are aiming at but I think we have two different approaches to getting what we want. For me, DR is nice, useful to have and great fun to play around with but it doesn´t always look nice (especially straight out of the camera) and it´s far from always necessary. For me the moldability of the BMCC is the key (while it preserves a natural looking image - with pleasant organic grain). F.i. I hate the "Alexa look" these days. It looks lazy, dslr and not one bit filmic.

  • @Aria

    We can kind of think of these cameras as different Film Stocks!

    Yep, that's one way of thinking about it. GH13 for a normal day 100-320 ISO, GH2 for 800 ISO and GH3 for even higher, but what I have noticed from footages by others is that GH3 treats colour in a totally different way to GH1 and GH2, by having a whole lot less green. In most situations I quite like how GH1 and GH2 treat green, which is closer to film-stock.

  • Wow... there are quite a few people who prefer GH13 texture over GH2 and GH3. For a while now, I was beginning to think that I was crazy, or maybe of just bad taste.

    @endotoxic one of the most recurring confusions is that sensitivity is ISO. Not really. They are quite distinct from each other. Watch that video that I posted from 2:20 onwards.

    Another reason why I like GH13 is that it emulates closer the traditional cinematographic workflow - in a way that it does not make your life immediately easier by easily making available higher workable ISOs. So you have to light your scene, and by doing so, learn from the cinematographers whose movies you liked. You might think that I'm a weird guy for loving difficult workflows? Well, very often I type my screenplays on a typewriter (because the quality of writing improves dramatically), and if I had the resources to shoot on film stock, I would prefer that, but then the costs would sky rocket, especially with montage and sound mix.

    But then one has to ask which particular "cinematic" textures one likes. My personal favorite films are from 1990s and 1970s, so even the modern Kodak 5219 film stock is too "High Definition" for me. I watch those films in BR 1080p along with my own footages from GH13 and I'm quite satisfied.

    Panasonic should have worked to improve the DR and colour space (4:2:2, 4:4:2). Instead, they have improved sensitivity, resolution, ISO, etc, which is great, but does it deliver a more filmic look? No. Why they did it? It's straight economics -- so that they could put an improved chip into a bigger camera and sell it for much much higher price.

  • I'm actually somewhat intrigued by the new AF100A based off the idea that it might produce smoother gradation from it's new Faux 10bit output. We have a bunch of options with the AF100A, GH3, GH2 and GH1. It's really a nice little family of cameras that one could have as a tool set, all with slightly different characteristics. I like the idea of flexibility and variety. No single camera will be perfect for every situation. We can kind of think of these cameras as different Film Stocks!

  • Difficult to say. I definitely like the GH2 hacked over the GH1 period. But there are things to like about the GH3, and things that aren't so great. Until the GH3 is hacked and we can see what is possible I can't make a determination.

    I really feel that the GH2 and GH3 are neck and neck, except for the banding and dynamic range. The GH3 is the clear winner there, but it doesn't yet possess that nice "filmic" grain, and slightly softer image like the hacked GH2 running the high end @driftwood hacks like AN 444 and Intravenus. When the GH3 has those characteristics, it won't even be a competition - the GH3 will be king. For now, it's just in the running.

    that's MHO

  • @endotoxic Yea I understand,I'm not a techhead at all I just liked the hacked GH1 image for whatever reason.Far as the GH2 I have settled on the softer version of "AN Cluster 7" thinking it would resemble the GH1 more.I'm not all at a fan of the overly detailed hacks.

  • repost sorry..

  • @EYESOUL , damm you right, even pictures (on raw). They should have improved upon that sensor i agree...the question is not why the didnt... Its more like..how can we achive the best out of it.

    This is very important topic to me. From a cinematographic poit of view, its important to determine the diferences of sensor and its behaviour in type of light, iso, filter, lenses, and damm even temperature.

    I have secret passion for sensors, that is true..and the impression that GH1 was never fully explored by cinematographers cos GH2 buzz was around the corner, and VK making hack for it so quick, that took over GH1 maturenes

    Silicon can behave diferent in such complex systems... i wish i new more.

  • @endotoxic I agree and also liked the pictures taken with GH1 better.

  • Just for saying:

    @kronstadt @aria @endotoxic @EYESOUL

    prefer GH1 over GH2 and GH3 sensor.

    Anyone else?

    @shian can you make a comment here? you have experience with 3 of them and even post!!

  • Combined with GH1's colour rendering and codec, and Vitali's hack and IPowell Maximum patch, GH13 delivers very filmic looking imagery. In other words, GH13 could be a one-off "lucky accident" , a "freak of nature" . What GHx project should have done is keep the sensitivity low (or give an option to keep sensitivity low) and increase it's DR. That would achieve a more filmic/cinematic look.<

    ITs the best example i have read!! thanks @Kronstadt, your humble opinion makes a lot of sence here.

    I think too that GH1 has better "texture"

    its like GH1 had fixed ISO to work with, like film.

    @EYESOUL i have one question...how can you describe the "texture feeling" tha make GH1 series better for you?

    For me as i have expresed before, lack of detail, and better color reproduction is the base. Maybe its its pixel bining...maybe its matrixed. We could maybe call @lpowell or @cbrandin @driftwood . They maye have a better inside about why is GH1 image more pleasent when even detail is not that good. Maybe they think all this is not about sensor...maybe code... i dont know.

  • Part of being a film director is having a vision, knowing what you want and sticking to your guns. In a way it has to do with confidence, rather than stubbornness. When I first saw the GH13 vs hackedGH2 footages, I immediately knew that I liked GH13 more, and that I wouldn't be getting a GH2 any time soon.

    The funny thing is, when GH2 came out or when it was first hacked, these kinds of debates that would argue that GH1 was somewhat "more preferable" or "more filmic", were pretty much forbidden, or at least met with a lot of criticism.

  • @RRRR the word "cinematic"hasbeen used wrongly millions of times, but we know what is being meant by it - how closely can a camera emulate the look of a 35mm film stock. That's it there's no need to get hung up on it. Cinematic... filmic... etc

    I have bought my GH1 secondhand because back then only 2009 models were hackable. And I hacked it with LPowell Maximum patch (I don't know if there are better patches now). I'm not a videographer- just an enthusiast who wants to make a movie (or at least a digital video that looks to closely to a film that audiences wouldn't notice the difference). So far, I have been getting images so nice, that I have not purchased a GH2 yet. Maybe when the prices will fall further,I will get a secondhand GH2 only because it has higher workable ISO for dark scenes. So GH2 will be my B-cam. I will not be getting a GH3 because it's colour handling is becoming "cold" like most Sony digital cameras, which I hate. The next step up for me would probably be a BMC, but I'm still not sure about many of the factors surrounding it. As far as I'm concerned, GH13 (with legacy lenses, good Lighting kit and good audio gear) is a perfectly good enough tool to make a full-feature-length low-budget movie.

    Yesterday, I have written an e-mail to Steve and Jens at Zacuto asking them to include GH1-hacked in their 2013 shootout along with Kodak 5219 film stock, GH2, Alexa, BMC etc. Why? Because the hacked GH1 has never been featured in their shootouts. It would be interesting to see what their response would be.

    IMO, one of the reasons why GH13 produces such a cinematic imagery at ISOs below 320, is because it's sensitivity is actually lower than that of any other camera in that range. Watch this video to understand and pay attention to how low is Kodak 5219 film sensitivity:

    Combined with GH1's colour rendering and codec, and Vitali's hack and IPowell Maximum patch, GH13 delivers very filmic looking imagery. In other words, GH13 could be a one-off "lucky accident" , a "freak of nature" . What GHx project should have done is keep the sensitivity low (or give an option to keep sensitivity low) and increase it's DR. That would achieve a more filmic/cinematic look.
