I originally read the title as “This Guy Makes Any Camera Shite” and thought my cloud account had been hacked. I enjoy watching Brandon Li’s stuff, particularly the self shooting ones. Self shooting as in shooting on your own as though someone else is shooting rather than self shooting in the vlogging context. Tripods basically. -

It's a good start! Are you targeting a specific film stock to emulate? It seems like you're aiming for negative film now since you're talking about wide DR. Positive film actually has a lot more limited DR, generally speaking. The color images, while nice, don't really "feel" like any film stocks that I know which seems a little more digital. The black and white images, for me, feel like something shot on a modern t-grain film (T-Max, in particular). I think that's a combination of the sharpness of the image, the contrast applied, and the very fine grain. I probably wouldn't think of it if not paying close attention, though! -
I like film and retro filmic looks, but shooting Super-16 (or even Super-8) is still an expensive PITA. After some testing of my equipment, I've realised that my GX85 has image quality equalling or surpassing a Super-16 film camera (with some categories surpassing a Super-35 film camera) so in my pursuit of a pocketable, portable, fun, simple, and fast setup that looks like film, this project is born. The criteria is to work out how to get great images from the tiny setup that are enough like film that most people would believe it if you said it was shot on film. My approach is simply to compare the two and find the biggest differences and then work on bringing them closer together, 80-20 rule and all that. The first point of comparison is already known, the crop factor is similar (2.2x vs 2.88x) so making sure I don't go too hard into shallow DOF then this should be comparable. Second consideration is camera movement, shake, and how they'll be used. S16 film cameras can be hand-held, but they've got some weight so are relatively steady in use. 8mm cameras were designed to be hand-held and are much lighter, so will move more. The GX85 is far smaller than either, but has IBIS (and OIS with some lenses) so that should make it feel larger, but I'll have to watch out for parallax, which will give away the cameras lack of heft. Third is the DR. Film has a huge DR and I wasn't sure how this would go - harsh clipping of highlights and blacks will be a dead giveaway. Without knowing anything about its rec709 profiles, I shot an exposure test where I took shots one stop apart. Film negatives have a lot of DR, but print film has far less, with stocks like Kodak 2383 only having about 5-6 stops in the linear range of their exposure (between about 10% luma and 90% luma, before the rolloffs kick in). Bringing in my test shots and matching the contrast within my standard colour pipeline (based around the Film Look Creator tool in Resolve) I realised the GX85 has enough DR to push its highlights well up into the highlight rolloff curve of the FLC, and same with the shadows, so this is fine too. DR, check! Fourth is resolution and texture. The images should be soft and noisy, but how much? After reviewing a number of sources, I realise that there are all kinds of factors, such as the speed of the negative, how it was exposed (0... or -1 and pushed in post, etc), but often the biggest factor in softness was the lenses used, and the biggest factor on the grain is the processing that the streaming service does when you upload it! In this sense, I have a lot of freedom in these aspects, but I'll have to do further tests on uploading to YT. I have seen videos that have really nice grain in 4K, so I know it can be done, but my previous tests showed the YT compression really changes things, so I'll have to do more tests. Then we're into testing with real images and just seeing what we see. My first test was some random shots in the garden, just to have a starting position. The feedback I got (including one friend who practically lives to talk about film!) was that it looked good but needed more saturation. My thoughts were that I exposed too high (I'd forgotten that the LCD is deceiving and the GX85 has a lot of shadow info) and as such the highlights in the first image were clipped in the file and still show in the graded image. After this test I happened to watch a YouTuber go through their grading process and they said they exposed by putting the image in the middle of the histogram, which made sense to me and I realised this is what I should do with the GX85. Second test was just a few images while out and about. It's the GX85 and 14mm F2.5 pancake lens. I'd previously forgotten this lens is both a 31mm and also a 62mm (with the 2x zoom) and so is much more flexible than I was remembering, so I made sure to include some 2x shots to see how useful that was with this level of image degradation. I also decided to push the images to get more of the kind of look I'm chasing. The 2x seems completely fine too, having quality far more than this level of softening will show. I also re-graded them in B&W, pushing the contrast much further. I may even want to go harder on these. Much more work to do, but I'm really liking the process so far. In these days of digital perfection, the attraction of film is in the colours and the texture. If you want the colours and not the texture, wanting to keep a much more modern level of sharpness and noise, emulating some of the properties of film is so ubiquitous that I think it's just called "colour grading". The phrase "film emulation" then is for the texture of film and deliberately wanting the imperfections and aesthetics of it. You don't have to go hard like I have with Super-16 film + Super-16 lenses levels of softening, but if you did this is easily possible too and FLC has 35mm presets which soften, but do so far more subtly than this. I'll continue to iterate on the colours and textures, but moving into moving images is probably next, with all the testing of the YT processing and compression that comes with that. But seriously, imagine telling someone in the 80s that you could fit an interchangeable lens camera capable of shooting feature-film level images in your pocket... Feedback welcome. -

I think it's inevitable that the original footage is not kept and only the edited and exported video is stored for the long term. If you want to be able to re-edit footage in the future then the intermediate storage format has to be selected to accommodate this. The 7K comes from use of a sensor that has sensible resolution for a broad variety of still photography applications and saving costs by re-using the same sensor in a bunch of cameras. A camera that is genuinely made for video and only video would likely be more expensive, and so video users have to deal with the large files if they want to shoot original files with the best quality. But one can presumably choose to shoot 4K or even 1080p and the problem is alleviated. It's a bit like with cars: top speed helps to sell them even if it can never be actually used. -
Other than the price, that really is my only criticism. Pull out tilt 100%!
