Camera+'s interface now resembles that of Apple's latest mobile operating system.

Apple has a way of making a splash. Instead of a slow release of its mobile operating system like Android and Windows Phone 8, Apple had millions of iPhone users updating their phones all at once when it released iOS 7 last week.

App developers have had months to update their mobile software to accommodate the new iOS 7. When Apple's latest mobile operating system was released on Wednesday, many of the best photography apps released updates as well. 

For some app makers, iOS 7 was a good excuse for an interface makeover while other developers opted for more extensive overhauls. We went hands on with the latest versions of a few of our favorite photo apps and tried out some of their new offerings. 

Camera+'s new interface for iOS 7 is cleaner and brighter compared to its old app (right).
Camera+ still has the same editing tools that made the original a must-have app.

Camera+ and Hipstamatic get an interface-lift

App Store mainstays Hipstamatic and Camera+ both got makeovers in their first post-iOS 7 update. Camera+ saw the most changes, with the addition of exposure compensation in the capture screen, including a square crop in the viewfinder, and an updated look for its editing tools. But the app also feels a lot newer. The editing screen is lighter, with less white-on-black text and thinner fonts. It seems like iOS 7 was the push that Camera+ needed to clean up its interface and provide some fresh new features.

Hipstamatic's updates, on the other hand, are a little more hidden. Its capture interface is relatively unchanged, but once you try to share an image, you will find a brighter and cleaner screen. It has also released, for a limited time, the "Seven" Hipstapack with three new "flashes" and two new camera cases. (And no, none of them are gold.)

The brushed steel and more analog-looking buttons are gone in Hipstamatic's sharing screen. The capture part of the app and the Hipstamatic store, on the other hand, remain as charmingly retro as ever.

ProCamera and DipTic release brand new apps

The original Diptic creates customizable photo collages and can apply exposure and color edits to individual photos in the grid.
Diptic PDQ has all of the same functions as the original Diptic, but with a very different interface.

As an app developer, what do you do once when your app sales have plateaued and you don't want to push more in-app purchases? The answer usually falls into one of two categories: make a new app, or sell your app to a bigger company. ProCamera and Diptic have both used the release of iOS 7 as a chance to do the former.

Releasing a new app instead of just updating your old one is not just a money-driven decision by the app makers. By keeping the old apps the way they are, Diptic and ProCamera avoid alienating their core user base while attracting new users with brand-new apps.

Diptic's new app is called Diptic PDQ (for "pretty darn quick"). It's essentially a re-packaging of Diptic's essential tools to better fit the iOS 7 aesthetic while improving the overall "flow" of the app. Instead of the somewhat cluttered Diptic interface, Diptic PDQ keeps its editing and filter features hidden, prioritizing the placement of its grid options.

You can still access all of the editing tools from the old Diptic, but you have to tap on the individual photo to see them. By condensing Diptic's high-powered photo features into an easier interface, Diptic PDQ's app developers have created a new user experience and, yes, it is pretty darn quick to use.

There was a lot happening on the viewfinder screen of ProCamera's old interface.
ProCamera 7 compartmentalizes capture information into a sidebar and also allows for a full screen capture mode.

ProCamera has been around since the dawn of iPhone photography, and for the most part, the app hasn't changed. Over the years, more features have been added, and a few interface tweaks have improved the tools, but the look, feel and spirit of the app has remained constant. Instead of throwing away the old ProCamera to suit iOS's new aesthetic, ProCamera opted to create a new app. ProCamera 7 has many of the same features of ProCamera like separate exposure and focal point locking and live shutter speed and ISO readings on the viewfinder, but it also introduces some new tools.

ProCamera 7 includes square and wide capture formats, a 3D Tiltmeter and a full screen capture mode that hides unwanted information so you can focus better on the viewfinder. If those new features aren't enough to make you want to buy a whole new app, the cleanliness of the user interface might change your mind. In the original ProCamera app, you have to enter a separate Settings menu to find most of the capture options. In ProCamera 7, the menu pops up on a low-opacity over the viewfinder. 

In ProCamera 7's "Night" setting, you can set your shutter speed as slow as 1 second. 

Flickr lands a spot next to Facebook for iOS photo sharing

Now users can easily upload photos straight to Flickr from Apple's Photos app as the classic photo sharing social network has proudly taken a spot next to Facebook, Twitter and iCloud in the photo sharing menu.

Long before Instagram, Flickr was one of the first platforms to make social networking with photos commonplace. After a complete overhaul of its mobile applications, Flickr has made its commitment to iOS known, so it is only fitting that it has earned a spot next to the extremely popular Facebook and Twitter in iOS's native photo application.

Flickr has taken a spot next to Facebook in iOS' photo sharing tool.
You can add a caption and choose which Set you want to share your photo in and who you want to share it with.

In the coming weeks, we are expecting more apps to undergo major updates while other, brand new photo apps that take advantage of the new iPhone camera and flash emerge on the scene. Stay tuned to Connect for hands-on experience and breaking news on all the latest photocentric iOS apps.
