Apple iPhone 15 Pro Max RAW File Sizes

I Was A Bit Curious

This morning I was walking Maggie (my dog) and was thinking about a question that was posted on the forum.  The OP wanted to know if it was worthwhile upgrading to the iPhone 15 Pro Max.  Part of the question had to do with ProRAW file sizes.  

I had my iPhone with me and I thought I would take an informal look at file sizes for the different cameras on the iPhone.   There are plenty of places you can search on the internet for more detailed information about file sizes and how these different cameras work in the iPhone.  

The big selling point is that there is a 48 MP camera on the iPhone.  This format is available when using 1x camera or normal lens format.  More on this below. 

I’ll have more to share on iPhone photography, Apple iCloud and how to get your RAW files into Lightroom for editing in the future.  

Camera Settings

My iPhone camera is always set to shoot RAW by default.  You set this up in the camera settings on the iPhone. 

As you can see from the image below, this is what the top part of my iPhone Screen looks like.

The top of the iPhone screen shows that camera will shoot a RAWmax file. 48mp. This is set in the camera settings section of the iPhone. It is also set to open the camera to last settings used thus the camera will always shoot raw until set to something else. It should be noted I have the 2TB storage iPhone.

Below is the bottom part of the screen of my iPhone.  If I tap and hold for a second on any of the four setting for the lens I can see the 35mm equivalent of what the lens will be.  A dial will pop up if you hold the selection down, showing magnification settings and under the number the 35mm equivalent. 

 

You can see in this screen capture the camera is showing the main camera is set at 28mm.

By holding any of the camera setting buttons you make a dial pop us showing the full range of capture magnifications available. You can also see 35 mm equivalent focal lengths

Here Is What I Did

As I was returning home, I decided I would shoot a few RAW images using the different camera settings and a few with the cropped sensor telephoto setting.  I thought my house would be a good subject.  The light was quite nice this morning. After I returned home, I exported these RAW files to Lightroom. 

In case you have never done this, select the images in the Photos app and then go to File > Export.  Selected Export Unmodified and choose the destination.  These will export as DNG RAWs.  You simply import these into Lightroom and you are ready to go.  These then can be edited as you normally would.

I did not do any modifications to these files that you see below.  I included the info panels for each exposure so you can see the information from each shot.

The first image shows the files as they were displayed in the finder level with the files sizes.  You can refer to this image as you view the images by file name.

Here ids a screen shot of my finder with the files used in this article. Please note the file name and refer to the images shown larger below in this article. This will allow you to see the files sizes for the images shot in ProRAW at the different camera/lens settings.

The Images

These are the images that were shot at different focal lengths and the metadata from the info screen in the Photos app.

This is the .5 or 13mm setting image

This is the meta data for the 2X image. Notice the file size has dropped to 33mb. That's because this is being shot on a 12MP sensor. But it is still a RAW.

This is the 5x option. This would be a 120mm equivalent 35mm lens.

This is the info for the 5X setting which an equivalent of 120mm. Once again notice the file size for the RAW file in comparison to the others.

And finally, for giggles and maybe a grin . . .

Finally this is the image with the zoom all the way out which is a ridiculous 577mm equivalent. Not really great but in a pinch it's not bad especially coming from an iPhone. Some magic could be done in post processing to make this even better.

I tried one exposure going to the max zoom. Obviously this is a digital zoom and cropped sensor. Still not to bad for a phone and optical zoom. It could work in a pinch and post processing magic can be applied.

Final Words

The iPhone is a useful camera, and it makes great images.  If you can use the normal (1x) camera, you get a really nice 48mp RAW file that can then be fine-tuned in post-processing.  I use Lightroom for this processing as they have a great profile made for Apple ProRAW; it’s a camera that is always with you.  I have made some great images and some amazingly good large prints.  Many of you may have seen my article On How Big Can You Go.

There is a lot of confusion about the iPhone and its clever marketing regarding file sizes and such.  I hope this quick article may have explained a bit more about what to expect from each of the settings.  I have always had a camera with me wherever I go.  The iPhone has made it possible to leave some of my bigger cameras behind and still have the confidence that I have a capable camera with me.

I do consider the iPhone to be an indispensable tool.  It is great for doing geo-tagging and using the photos app; it actually shows you where images were made.  I use it a lot for workshops, not only to get me back to previous locations but as a teaching tool.  It allows me to show attendees on a workshop composition I am seeing and help them understand how I see something right there on the spot.

Rumors are already surfacing that the next iPhone will have a larger telephoto lens and be capable of doing higher resolution RAW files with the different sensors or lenses in the camera.  The iPhone, as well as other mobile phones, are certainly affecting camera sales.  For many people, their iPhones are all the cameras they need.  A number of well-known photographers are making a big deal about how they shoot only with an iPhone.  One thing is for certain: it is only going to get better in the years to come.

I am on a yearly trade-in plan for my iPhone.  So, I get a new iPhone every year.  I pay a monthly fee of $70.00 USD for the 2 TB iPhone 15 Pro Max.  That is less than a $1000 a year to have a 48MP camera in my pocket.  At the present time, in just the photos app, I have 118,314 photos and 775 videos on my iPhone.  I have images broken down into albums.  The search feature on the photos app is pretty cool and super smart.  Type a word like “Fire Truck”, “Cat”, “Jeep” and in less than a second you have all the images that it sees for those searches.

Say what you will or want.  I’m an Apple fan.  I have had Apple products since they were first introduced.  I have invested heavily in Apple stock and have had phenomenal returns.  While I have certainly been frustrated with Apple products, the service has always been prompt and great, and things tend always to work.  My Apple devices, and especially my iPhone, get the job done.
