I find it really admirable that Halide team writes some great articles on Smartphone computational photography.<p>Those who are interested in this area should check out their explainer article on what’s iPhone’s ProRAW format: <a href="https:&#x2F;&#x2F;lux.camera&#x2F;understanding-proraw&#x2F;" rel="nofollow">https:&#x2F;&#x2F;lux.camera&#x2F;understanding-proraw&#x2F;</a><p>I’m from this field (tech for phone photography) and it was really helpful.

I have a 13 (not pro), coming from a Pixel 2. I used it almost exclusively while tramping around NZ for a month. It&#x27;s definitely good enough to replace a larger camera for day-to-day adventures and the ultra-wide is very useful. I put my mirrorless in a storage unit for the trip because it wasn&#x27;t worth the weight, and the only thing I missed was the telephoto.<p>I do find the HDR to be a bit in-your-face, even on &quot;neutral&quot; settings. Sunsets are very saturated when you want to take a picture of pastel shades. Cloudy or sunny skies are a bit hit or miss, often there are blown highlights. The lens also seems much more susceptible to flare at night than other phones I&#x27;ve used with the dreaded green dot - not something I ever noticed with the Pixel. Motion photos are pretty great, really handy for low-effort blur on moving water, although you have to use Photos. Google Photos will play the clip, but it won&#x27;t do the long exposure&#x2F;bounce modes. Also a pain if you subscribe to G Cloud (which can sync photos fine), because iCloud is incessant about not having enough backup space. I tried Halide, but I didn&#x27;t see a significant advantage over Slow Shutter Cam which costs a couple of bucks - if you&#x27;re going to shoot raw, you&#x27;re going to edit it somewhere else anyway. Maybe aperture and focus control is worth it? The risk with shooting in RAW and post-processing, is that the camera isn&#x27;t really that good compared to a larger sensor and you&#x27;re relying on a huge amount of computational photography to fix those limitations. I did try some astrophotography resting the phone on the car roof, but it never really worked.

&gt;In the iPhone 11 and 12, I found it useful to have the ultra-wide in my pocket— way more useful than the iPhone’s Panorama Mode— but I still mostly avoided it. It was ‘fixed focus’, which means there is no way for the lens to adjust what is sharp. It was designed so all of the frame was in focus. This caused smudgy images, trading clarity for a wider field of view.<p>This part doesn&#x27;t make a lot of sense. The iPhone 12 ultrawide is fixed focus, so it&#x27;s sharp if your subject is at infinity (which is pretty close, given the focal length) and blurry if it&#x27;s not. There&#x27;s no reason why having a fixed focus should yield &#x27;smudgy images&#x27;. I guess maybe the article is suggesting that the fixed focus is set at a hyperfocal distance to increase the sharpness of closer subjects. I&#x27;m not sure if that would really make sense for such a short focal length, though, as the majority of elements in the frame would typically be at infinity.

I had to return my iphone 13 pro max twice because the pictures were blurrier than my iphone X. I don&#x27;t know if the reviewers and prominent users get the tested and calibrated models from Apple. Here is a discussion on Apple forums on how bad iphone 13 pro max cameras are in the wild.<p><a href="https:&#x2F;&#x2F;discussions.apple.com&#x2F;thread&#x2F;253181534" rel="nofollow">https:&#x2F;&#x2F;discussions.apple.com&#x2F;thread&#x2F;253181534</a>
