Traditional exposure compensation works this way. When you change the EC dial/settings you're changing the shutter speed or aperture or ISO depending on what mode you're in. The camera takes the exposure settings you've manually entered, or set on Auto, and it is adjusting one of the three parameters to under or over expose. So let's say you're at ISO 200 and the aperture and shutter speed are fixed manually. In other words, Iso is the only variable that you can change in that mode. If you change the EC down one stop, the ISO switches to ISO 100. Dial the EC to +1 and the ISO goes to 400. Likewise if you have ISO and aperture locked and you are at ISO 100 at f/2.8 at 1/500th of a second, dialing EC down by one stop makes the shutter speed 1/1000th, and up makes it 1/250th. So, this IS exposure compensation, same s on a camera.
Well, not really. The difference here is you can’t adjust the aperture, only shutter or ISO. So when those are locked there’s nothing else to adjust. And also you can only use exposure compensation when you’re in auto exposure mode.
Although not to do with this I would love your advice about banding in the sky. I am at the moment in India filming mainly on my iPhone 15 Pr Max, a variable ND filter and the BalckMagic camera app. I am using ProRes HQ and Apple LOG. What I am finding is at times I am getting banding in the sky which I find rather odd as ProRes HQ is supposed to be 10 bit which generally I thought should not give banding. I am viewing the rushes on my iPad Pro in DaVinci. Would love your thoughts on this as although I can remove it in DaVinci I would rather not have it there in the first place.
I’ve not seen much sky banding with ProRes, but it can happen on any camera. And if you’re accidentally shooting too high of ISO due to the VND and/or if you’re crushing the sky too much with ND that can affect it. I’ve had both those inadvertently happen. Blue skies can definitely be tricky. You might try a test shooting without the VND and see if it improves. But you’re right about the 10-bit video aspect, though again it can definitely happen. I’ve actually had it happen with my RED Komodo shooting 16-bit raw.
@@iphoneographers Thank you for getting back so quickly. I am shooting at 100 ISO with ND set to around ND400 (Oh how I wish they would all use the same measurements for ND). I will do a bit more experimenting but it is good to know you have not experienced the problem. DaVinci fortunately seems to remove it OK with the Banding filter on the colour page.
What I find very odd is shooting in Apple log, using a lut, and false colour. False colour is BEFORE the lut, but it’s only after a frustrating hour I realised this. And there’s no way to swap them. It just seems I’m more likely to crush highs and lows
Yeah it can be tricky and I also don’t completely trust zebras in the app. However, if you find a LUT you trust then load that and you’ll be good in most cases - even can auto expose and then lock it.
Thanks heaps, much appreciated 😊❤ So are you saying it's changing the iris, therefore the dynamic range level, depends on how wide the aperture is? I've found a workaround and it's by pressing down on the screen, until the AE/AF lock shows up Unfairly there's still no auto ISO I think 😢
The aperture is fixed so that doesn’t change, so the exposure changes via the shutter and ISO. And yes, can lock everything by pressing & holding on the screen. But no auto ISO when shutter is locked!
love the video, but this is ridiculous front part of Blackmagic, we need to have a control to block iso, and block shutter separately, this will be amazinggg
Interestingly I don’t think you can. I’ve wondered that in the past myself. They have a feature where you can trigger the flash when you start recording, but it won’t stay on constantly - at least not that I can find.
AT 0:48, how did you get that exposure control in the native app. I have 15 Pro and have never seen that option. In fact the Apple support docs for the camera do not even mention it.
When your phone is in landscape, look on the left side and you’ll see a small arrow. Click that arrow then on the right side you have some controls that pop up. And also go into your Camera settings in the phone menu and then Preserve Settings and make sure Exposure Adjustment is selected.
@@iphoneographers Preserve Exposure Adjustment setting. THAT was the secret! Thank you so much for pointing this out. As it is off by default, I am sure a lot of users missed this setting as well.
After going through all of the cameras app I have on my iPhone, none of them have the ability to lock SS and allow auto ISO. Please share if you have an app that does this. Thanks in advance!
It’s my understanding this is an issue with the phone and not an app. Likely to do with phones being fixed aperture. Although seems to me like it’s something that could be implemented, but at this point no one has it that I know of.
@@iphoneographersI honestly don’t understand what it has to do with a fixed aperture. You can just use the other two variables. For photos, like in a Timelapse where the light is changing, I’d like these to allow me to expose how they will (using an exp comp or not) but with a fixed ISO. I could also set shutter min and max values, for example.
Came here to find out how to lock Exposure so that both Shutter and ISO can be LOCKED. I didn't find that answer. I don't want my iPhone to make scenes brighter or darker because something in the scene changed brightness. Please tell us how to do that in the Black Magic app.
@@iphoneographers If that is true, why then does a LOCK icon not appear on the ISO? And, why then does the iPhone change the BRIGHTNESS of the scene when the brightness of an object in the scene changes? For example, I am filming an LCD monitor. I start the iPhone recording a video using the Black Magic app with mostly white filling the center of the LCD I am filming, then when I clear the LCD I am filming so it displays nothing but black, the iPhone tries to adjust brightness. But I don't want it too! In fact, it should not do that! But it is. And this is why I said ISO has no lock icon and therefore it must be the ISO or something else other than the Shutter (which is LOCKED) that is allowing the iPhone to change the brightness in this case. I can set my Panasonic GH5 to manual settings and avoid any kind of automatic brightness changes by the camera. But on my iPhone 15 Pro Max with the Black Magic app, how to do that is a real mystery to me. That's why I Googled, found your video, watched it, but then found it didn't help me resolve the problem, so I posted my previous comment.
Google “iPhone dynamic tone mapping”. That’s what you’re dealing with. The phone will slightly “auto adjust“ in dark or bright situations even if all the settings are locked. That’s been an issue since the iPhone 8. DTM is really designed for photography where it’s fine, but it happens in video too and is not good. However, if you have an iPhone 15 Pro or an iPhone 16 Pro you can shoot an Apple log and dynamic tone mapping is turned off. This video is a few years old and shows FiLMiC Pro, but it explains what’s going on… ua-cam.com/video/tn6xL5oE25w/v-deo.htmlsi=YHpZYBEw486702ca
I'd lock the shutter at 180, lock the ISO as low as your shot is happy with and then use a variable ND to tune the image. You can get clip on filter holders or bodge a fliter over the lenes somehow.
BlackMagic app works like a camera program. They have to make different modes like shutter priority or iso priority (aperture priority is not possibile because the IRIS is locked on the iPhone ) So to have shutter locked and exposure compensation ( and not ISO control to compensate the exposure ) they have to make a shutter priority mode. Now or you have full auto or you have full manual. There are many request for something like this either to the blackmagic app reviews to the apple store , and some forums. Hope is the feature Blackmagic give us this features because also personally most of the times i shoot with Shutter priority mode with my Sony Camera. The only app that does this Cinema P3 that have this function and many other useful option like max ISO settable , bitrate to any codec that you set for capture etc etc but unfortunately is not so stable like Blackmagic.
When I did a quick video test last week, I got so confused that I switched back to Cineam P3. I am sure Blackmagic Design will work this out. I am grateful to BMD for giving us so much to work with at no cost.
@cliquemediaproductions Yeah, I use Filmic Pro a lot still b/c I’m used to it. But BMD is nice especially for a brand new app that’s free, so I’m trying to get used to it.
@@iphoneographers I tried, does not appear in the menue 🤷🏻♂️. is it because it‘s an iphone 13 Pro. I have the latest IOS and the latest BM camera app version 🧐 I only have 30 fps in 4k and 60fps in HD to choose from 🤷🏻♂️
Hello! How can I have auto ISO but the shutter stays the same? I shoot real estate and need the auto feature while keeping the shutter 180 degree rule… thanks!!
This is a big frustration as Blackmagic Camera App is NOT offering that. Not all situations give you enough time to manually adjust all parameters of the exposure. For run & gun, auto ISO is indeed a must have feature. The app CinemaP3 is doing that.
It's the strangest, most complicated system one unclear mind could ever design. These controls have been standard and practical for 100 years but Blackmagic was able to kill it.
Not sure this is accurate. When in full manual mode you can choose how to under or over expose your scene😮 yes the aperture is fixed so you can only manipulate speed and iso It works as it should 😊
You manually expose a shot with ISO and shutter of course, but you can’t under or over expose a shot with “exposure compensation” in manual mode. That only works with auto exposure.

Yeah for run & gun type stuff like that it would be nice.
Me too
Really useful clarification thanks. I lock off shutter and ISO and use a variable ND.

So there is really no option to set ISO to auto and keep Shutter angle fixed at 180 deg.? That doesn´t make sense to me. Do I miss something???
Correct. No auto ISO with shutter locked. Maybe someday.

Does the app shoot AEB? If not is there an app that you recommend for that?
Are you talking about bracketing with still photos? If so, this app shoots video only.

Why you’re using 180 shutter with 24fps? Shouldn’t you use 50?
This is set to shutter angle, so 180° would be for every frame rate. Same as 24fps = 1/48 or 25fps = 1/50, etc.
