With iOS 17, you can now shoot 48-megapixel photos on your camera without having to use a really large file size in the Pro formats. Here’s how you can change the settings to enable this new mode.

We’re going to jump into the Settings app to begin with, and then we’re going to scroll all the way down until we find Camera. I’m always surprised how far you have to go to get to Camera, to be honest. From here, we’re going to tap onto Formats. From this screen, we’re going to tap onto the Pro Formats option, and here you’ve now got three options. The new one at the top is 48mp HEIF, and that stands for High Efficiency Image Format. It’s going to capture all the data with the 48-megapixel sensor, but it’s going to do it as a much smaller file size than the old ProRaw setting that you might have used before.

So, what I’ll do is I’ll choose this new HEIF option as my default, and then I’m going to jump straight out of Settings and into the Camera app instead. Now, in the top right corner, I’ve got a new option to change formats. At the moment, you can see that 48-megapixel HEIF is turned off. That means when I get a photo, it will do the normal 12 or 24-megapixel resolution. But if I tap on here, it will enable 48-megapixel mode for me. Now, when I use the shutter and take a photo just like normal, I’ll get a 48-megapixel image instead. I can also tap and hold that format button at the top, and I can choose between Pro RAW or HEIF or regular as well. Now, those images will be captured. I’ve got one standard 12-megapixel, 48-megapixel HEIF, and a 48-megapixel ProRAW. Let’s have a quick look and see how the file size compares to those three images.

As you can see, the HEIF is right in the middle, and it’s a much smaller size than ProRAW. So, you get all the data of the 48 megapixels for about a tenth of the file size that you would have had before iOS 17. And that’s just another way that iOS 17 has made your phone better than ever.
