This article is intended for advanced photographers and, of course, programmers.

As an imaging and iOS programming pro (see my latest Nokia Lumia 1020-specific article), people often ask me about the photo and video capabilities of iOS. While I'm currently working on no less than four major tutorials & roundups (panorama, HDR, low-light, and action shooting) I'll publish in the near future, I've decided to dedicate a “quick” separate article to a forum question HERE. Note that my HDR (High Dynamic Range) shooting article will build on the information in this article so that advanced users know how exposure compensation can be done in the best way on iOS.

Note that I'm discussing both bracketing and, generically, exposure compensation. The former is based on the latter—you generally shoot more than one exposure-compensated shot to get a bracketed series of shots, typically, for future (HDR etc.) processing. This also means that, as long as you understand what exposure compensation is, you'll also easily understand what bracketing is.

I have four regrets in my life:

1.  A tattoo of an arrow that starts under my right armpit and runs down my side, past my hip. It’s big, bold, and will most certainly look like a crumbled, smeared watercolor painting when I’m 60;
 

2.  The tattoo I got one Saturday night in Soho during a two-week trip to London circa 2004. This tat-ta-roo on my ankle of a heart the size of a fist looks like it was drawn by a 4-year-old with a permanent marker and underdeveloped motor skills;

3.  Letting my parents develop the disposable cameras from that trip. (My mom still can’t look me in the eye.);
 

4.  Dumping my iPhone 5 for the Galaxy 4. 

There are many compelling reasons to teach children sign language at a young age. For some, it is a valuable skill they will have for the rest of their lives. For others, it is a necessity due to a medical condition or developmental delay. No matter the reason, there are apps out there that help teach little ones sign language. The icing on the cake is that all of these apps are free, which makes them accessible to anyone with an iPhone. 

VLC for iOS Returns to the App Store

By Werner Ruotsalainen

VLC is probably the best all-in-one multimedia player for both Mac OS X and Windows. It also has ports on mobile platforms (or will have when Windows RT and Windows Phone 8 are concerned).

The iOS port, which was released back in 2010, had a stormy history. Shortly after its release, it had to be removed from the App Store, only to return almost three years later, this week VLC for iOS (free). Before, the only VLC version available on iOS was from Cydia, the jailbroken App Store. The Cydia version of VLC has always been the same as the 2010 (initial) version of VLC.

The removal of the initial version of VLC has understandably caused quite much uproar because people tend to think of VLC as the best of all players no matter what platform it's running on. This, unfortunately, hasn't been the case of the initial (2010) version – actually, it has been one of the absolute worst players in terms of compatibility, features, and efficiency. As I've always recommended in all iOS forums, you simply didn't want to use the then-current (2010) version of iOS VLC, because it was plain inferior to the top App Store players (GoodPlayer, It's Playing, AVPlayerHD, nPlayer, HD Player Pro (currently unavailable), RushPlayer, BUZZ Player HD. etc.), and Cydia ones (XBMC, RushPlayer+).


Apple is preparing to upgrade its mobile operating system to iOS 7, and with that, we can expect to see a host of new features on our iDevices as well as significant improvements to already-existing features and apps. One of the things I'm excited to see is how mobile gaming evolves with iOS 7. On that note, it seems appropriate to feature a serious gamer’s headphone. Hardcore gamers and audiophiles alike will appreciate the quality of sound of the V-Moda Crossfade M-100s ($310) over-the-ear headphones. 

While many companies develop great headphones, very few pour as much time, energy, and resources into research and development as has V-Moda. The Crossfade over-the-ear headphones are very much the product of extensive crowdsourcing and feedback from a variety of audio experts and connoisseurs.

Although marketed primarily as a device for recording and broadcasting Xbox 360 and Playstation 3 gaming exploits, Elgato's Game Capture HD ($179.95) also can capture iPad games and productivity software. By pairing it with a laptop and an Apple Digital AV adapter, the Game Capture HD records and broadcasts iPad content in glorious high-resolution video. With the press of a button within the Game Capture's software interface, you can also stream the video to YouTube or gamer-centric Twitch.tv. Read on to learn more.

Elgato's support of the iPad has been surprisingly strong, producing both the eyeTV and eyeTV Mobile for iPad users.

I installed iOS 7 beta 3 on my iPhone 4S a few days ago and have had some time to check it out and the results are in—my iPhone works again!

For those of you who installed beta 2 on your iOS devices, you know what I'm talking about. With beta 2, I couldn't take a picture without shutting down and restarting my iPhone. I often had to tap the surface several times before my tap was recognized, and a few times each day, my iPhone would simply reboot itself.

This is par for the course for an early beta of any software, especially an operating system. However, I wanted to install the early betas of iOS 7 on the devices I use on a daily basis because it's the best way to become intimately acquainted with this revamped version of iOS.

This article is intended for iPhone 4S and 5 users who want to shoot video at 60fps (double the framerate) using iOS 7 as well as programmers wanting to support the new 60fps mode in their apps. No iPad or iPhone 4 users should read further since, to my knowledge, their hardware doesn't support 60fps.


Executive Summary

iOS 7 will support 60fps video recording at 720p (as opposed to iOS 6). While it does have image quality problems on current, compatible iPhones (4S and 5), at least it works.

This article is highly recommended for programmers and people interested in shooting video.

As of iOS 7 beta 2, the built-in Camera application can't make use of the extra pixels of the sensor when zooming. Only custom-written, third-party apps currently can do that. Hopefully Apple fixes Camera in the final version of iOS 7; before that, should you want to use zooming while shooting video, avoid using the Camera app and make sure you write or install an iOS 7-specific video recorder application for best results.

Many of my readers have asked for a complete elaboration on the brand new zooming features of iOS 7, both in the stock Camera application and the programmatic API support (AVCaptureDevice.videoZoomFactor and the related, highly useful properties AVCaptureDevice.activeFormat.videoZoomFactorUpscaleThreshold and AVCaptureDevice.activeFormat.videoMaxZoomFactor).

Welcome to my iPhoneography workflow. Here, I'll share the images I create with my iPhone and the hand-picked, trial-and-error methods I use to capture and edit them with.

This image I took recently, titled "Sunday Serenity," is a very easy-to-approach iPhoneography photo. I want to share a few quick tips first off. Using your iPhone to take professional-looking photos involves a little manipulation. Trying to get those far-away landscape shots with your iDevice can be difficult compared to using a DSLR camera.

In this photo, the sun was about to come up, which is THE BEST time to catch sunrises (for sunsets, the best time is right after the sun goes down). It all relates to lighting, and colors are more intense before or after the sun makes an appearance.
