ProCamera.

I’ve been a loyal ProCamera user since its early days on the App Store, and with every major release it continues to raise the bar. I have purchased nearly every premium add-on, including RAW Exposure Bracketing, Auto Perspective Correction, Private Lightbox, the San Fran Filter Pack, Food Filter Pack, Low Light Plus, and vividHDR. Every one of these features has been worth the investment. With ProCamera 18.3 running on my iPhone, I can confidently leave my DSLR at home for most trips. The image quality, manual controls, RAW capture, HDR capabilities, and low-light performance are simply outstanding. The app gives you professional-level control while remaining intuitive and reliable. One feature that has been especially valuable for my real estate photography is Auto Perspective Correction. It quickly fixes distorted vertical lines with a single tap, producing clean, professional-looking images without extra editing. It has become an essential part of my workflow. The developers deserve tremendous credit for continually improving an already exceptional app instead of simply maintaining it. Every update brings meaningful enhancements, improved performance, and new capabilities that make photography even more enjoyable. If you’re serious about mobile photography, ProCamera 18.3 is, in my opinion, the gold standard on the App Store. Whether you’re a casual photographer, a content creator, or a professional, this app delivers results that consistently exceed expectations. If I could give it more than five stars, I absolutely would. Highly recommended!

The application is initially free, the developer indicated that there is no "In-app purchase" in this free application. But when you download this application, it turns out that you have to activate the trial subscription period for a week, and then switch to a regular subscription.

I click anything and “Oops, looks like you tried to use our free app. Did we mention everything is locked behind a pay wall?” What’s the freaking point of making the app free if you’re not even able to use the app without paying???

This would be my default camera app, except… 1) I take a lot of wildlife videos and listen to podcasts while I’m out walking. The default camera app lets me continue to listen while I have the app open, but it stops when I open PC in video mode. 2) I wish there was a way to switch between the 1x and 4x lens while the video is running. I understand that not everyone has the same workflow/shooting style, but these are two small but nonnegotiable features for me. If I had them, this would be a 5-star app and upgrading would probably be a no-brainer.

THE BEST!!! First I’ve been using this app since the iPhone 4S now on my iPhone 13 Pro Max still the best - Photo quality choices, choices, choose TIFF etc. Photo, Video, HDR, Night mode, Q scanner, Builtin editing, filters & more. Crop W/built-in sizes, flip horizontal, straighten. Flashlight with different brightness setting's, choice of App library or iPhone Photo library. Choice whether or not to keep photos or delete later right from the app! Shooting in HDR automatically keeps both HDR & regular photos or just HDR when editing photos keeps original image I think this is the best photo app I've used on my iPhone 6 or 4s & I do believe I had the previous version/app on my 3Gs? It's still the best & running great on my iPhone 13 running iOS 18.4 but you will have to learn how to use it! There are a lot of options although you can make it simple or use it as an expert in (expert mode) which is still easy once you get the hang of it. I think using the previous version helped me to move to the newer versions. Best of luck...

.. And that’s a lot of trust- occasionally my work is extremely poignant. Art. Whatever. And I want as much control as possible MANUALLY because MANUAL ANYTHING IS BECOMING A LOST ART! Update: Went all out full purchase for all functionality, support these developers cause they kinda really REALLY are handling things properly compared to the rest. They GET that neural imaging is not something every user wants futzing their work.
