Love the content as always. I personally from my testing would say that I would still try to keep my iso low for bright scenes but I have gone to iso 800, 1600 and been pretty happy with my results but I would not say that it is worth it to shoot at higher isos even in bright scenes. It all depends because I used it as a way to add film grain since I was shooting humans. If you were shooting a commercial for a product like soda or a snack then the clients might want it more clean. I get what you were saying and it is true that people should not be scared but people should be also thinking about why they should raise it. I also keep my noise reduction at -4 to get more noise/pleasing image since I hate how noise reduction smoothes and destroys images. What setting do you keep yours at. Great video once again.
You literally just fixed the biggest thing holding me back from getting the shots I want! All I’ve ever heard from day one was drop the ISO. Thank you for opening my eyes to the actual functionality of it and how to use it properly. Super informative. Just ordered a new Voightlander lens too based off what I’ve seen in your other video. Loving the content.
@@RhettThompsonFilm do you mean? aperture and shutterspeed first than if needed add more light (artificial or natural) and as a last resort adjust iso?
Maybe i'ts just my taste or style but I love the way the gh5 looks when it's a bit underexposed and you bring it up rather than perfectly exposed. (using v-log)
I enjoyed your discussion. I have two GH5’s and GH5 Mk2. I shoot live theatre, concerts and dance shows. I live at ISO 400 and 800. Normally I don’t think about ISO but recently I spent a couple of weeks in the Caribbean and it was extremely bright. I used a variable ND filter but all my video footage was rubbish. I’m old and I couldn’t see what was in focus and what the exposure was really like. I think my ND filter was poor. I also think that not being able to use a matte box or lens hood made a difference.
Hello from Toronto! I shot my last two short films on my channel with the GH5 and Leica 12-60mm. I had nooo idea about the effects of highlight roll-off when you use a low ISO vs. a high ISO. You can see in my "Rat Race Blues" film that I could've used that technique for a couple shots. I wish I saw this video earlier!!
Just gotta be a little careful! Also consider getting a black pro mist 1/8! It makes the highlights glow a little and they feel like they have better rolloff.
Nicely explained! Learned something new about the iso, and was curious about what the lowest extended iso vs native iso were in contrat to one another. Thank you so much for explaining
I totally agree with the dont care part Some of my first videos i shared with people were really overly exposed and noisy, but those are the actually the ones i have gotten some of the best feedback on. Personally i can't go over 1000 ISO because i instantly notice it and i feel like my footage is just completely ruined. I'm just really picky with noise and i think most of us are, noise has gotten itself a bad reputation which it doesn't deserve Great video man
I've done some testing since and you are correct and right about that 100. Thanks for answering my question. NObody is saying this anywhere and I'm a GH5 nut and watched every GH5 video out there. I know there is an a announcement coming today but most people say we won't see GH6 until 2022. What do you think?
Have you tried iDynamic for video - setting ISO to auto and use iDynamic (set to auto) in a room with background window daylight shooting inside which provide a much smoother dynamic range between the window daylight and internal
I was always steered away from those options but if we are being honest I haven't done nearly enough testing to know how well those options really work or not. Future video...?
Personally I use the exposure meter on the screen a little bit in conjunction with the histogram and spot exposure tool. Despite exposure is so helpful to make sure your subject is exposed correctly because everything else really doesn’t matter!
@@RhettThompsonFilm thx for pointing me into the right direction. Vlog not recommended for low light in general because of increased noise i read on the internet. I guess i have to test out for myself 🤷 thx for the help!!
QUESTION RHETT THOMPSON? On High Quality Bit Rate Long Run VIDEO'S...DO Either GH5 Or Olympus EM-1 MKII Video FILES Get Split Up Into Multi Piece Bits? IF One Does But The Other Doesn't ..PLEASE Tell Me Which One Does & Which Does NOT? Or IF Both DO? I'M Of Course Wanting One That Just Spits OUT One Big FILE & Not a TON Of Multiple Small 2GB FILES That Needs Special Software Stitching Together? THANK YOU🙂
That’s an interesting proposition for sure. I would try to do some more research on this if you can because my firmware might not have been up-to-date but the lens did not seem to be parfocal on my GH4. I’m not 100% sure if my camera was out of date software wise but it was kind of strange. That being said the manual focus clutch and aperture ring work well. It’s a very expensive lens for sure and I really like it but I may consider renting it first if I were you and see how you feel about it. And I’m sure you’ve done this research as well but you could be someone who the sigma 18-35 works better for. Let me know if you have any other questions!
This is actually a great question. Some have said the native ISO is 400 no matter what but if you look at cameras like the S5 they have different native ISOs for the different. The info is a little spares out there but it seems in Non-Vlog and non-HDR the native ISO is 200 but I'm not 100% on that.
Photos is different for sure and I was talking about video since it has more stuff applied in camera that you cant turn off as easily. For raw photos Im not sure...might warrent a follow up video.
Considering I have more than enough light available and a variable ND to fine tune the exposure, so that I can choose whatever ISO I want: What ISO is generally best when NOT shooting in Vlog? I heard 400 is best for Vlog, but I´m using CineD. So I guess it´s either 400 or 200, but people say different things. And by the way, I´m not on a snowy mountain or something like that, just wondering for my general go-to ISO setting. Thanks a lot in advance!
So if I am shooting a night time rocket streak shot, where I will be using the long exposure noise reduction function as I will be exposing for 4 minutes or more, will the extended ISO100 benefit me as I go from a smaller aperture like f16 to a larger one like f10 of f8?
Stop. This whole video is about how iso shouldn’t be used for basically anything. I guess theoretically maybe you might see a 1% noise reduction but the highlight rolloff is so Awful I wouldn’t use 100 unless you’re desperate
Thank you for the video. I have many different camera brands, but Panasonics such as my G85 colours - specially on faces - is horrible. It creates extra red and yellow colours that's very hard to remove in post process. Wondering if you have or noticed similar issues.
@@RhettThompsonFilm Hi, Rhett, Yes I guess it happens when there is not enough light - I use Standard profile. However, I don't have the same issue with Olympus, Nikon, Canon or Fujifilm in the same scenario. Also I think there is lots of color noise. Thanks for the reply.
thanks for these reflections on ISO ... on another note, are you wearing the same hat as ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-leKJMfXZ1IE.html ? is it Lumix-recommended hat color?
You made the first mistake 6 seconds into the video. XD ISO isn’t an acronym. It comes from the Greek word isos, which essentially means equivalence. The ISO website itself that coined the word explains it meaning and derivation on their website. (If it was an acronym it would be “I.O.S.” For the International Organization for Standardization) So its pronounced “Eye-So”. Not “Eye, Ess, Oh”. :)
Yeaaaaah I know this and I honestly go back and forth with how I say it. I wouldn’t really call it a mistake per say since I feel the majority of people say I-S-O but technically it isn’t correct.
You are seriously confused both on how the camera works and what the implications are. On the GH5 ISO is not a complicated topic, the camera is ISO invariant when it comes to shadow recovery. You also make some confusion about definitions. The value of 200 on MFT camera is the base value where gain control is applied. The extended ISO values are those where highlight compression is applied. As your video editor does not expect that and does not know how to deal with it the highlights look clipped but they are not. 400 is simply the value where noise reduction starts working there is no benefit shooting at 400 vs 200 if you are exposing properly. I do not recall reading any documentation nor statement from Panasonic where they mention native ISO for any of their standard front illuminated sensor digital cameras. Some of the examples you use to make the point are also not well chosen like the black frames which only show that read noise on a standard front illuminated sensor increases with gain, this is always the case unless the sensor has a dual gain architecture. For a video that is supposed to help people not to make mistakes this is pretty confusing
@@gopolarisstudio where? Find me a reference. The manual has 174 mentions of the word ISO and neither base or native feature. If you find something please let me know
@@Interceptor121 www.panasonic.com/au/consumer/lumix-cameras-video-cameras/lumix-cameras/lumix-g-cameras/dc-gh5sgn-k.specs.html Ctrl-F "native". Note: if you are then about to counter with "but it's not the manual, I said the manual", then that would make you a dipshit. Fair warning, lol.
@@Interceptor121 lol shifting the goal posts now. You said Panasonic. Now I'll show you GH5 and it'll be "b-b-but it's not the manual". You got what you asked for.
Your video is making me nauseated. Lots of people cannot tolerate moving images which are shaky and not stable--it causes motion sickness and is a well known medical condition. It's a bad idea to have a handheld shaky camera just for the sake of having a shaky image. It is literally impossible for a lot of people to view your video.
@@RhettThompsonFilm That's okay, it seems that lots of filmmakers and others have no idea that shaky handheld camera motions can make a lot of people sick in just 2 seconds. I literally had to leave the theater when I went to see "Black Hawk Down"--I vomited in a trashcan. And this is a typical response to this kind of motion sickness. I couldn't watch Saving Private Ryan because of the use of the frame rate that made the motion look choppy. The director thought that it looked cool but all it did is make some people nauseous--it's a cheap gimmick that didn't exist in the days of film. So when I run into videos on RU-vid that have this kind of shaky motion, I have to immediately stop watching.
Underexposing is almost always the reason when people complain about noise. Panasonic doesn't help that because I think they cheat a little on their ISO ratings. I find that it's best to overexpose by ⅓ stop or, better yet, use the luminance guide and expose to the right without clipping.
