iPhoneography 101: Get great photos, and great control in iOS

iPhoneography 101: Get great photos, and great control in iOSI’m a nit-picky little punk. Ask any of the truly wonderful creative people with whom I’ve had the pleasure to work (who will no longer work with me). Also, I love taking photos, and I love punching them up to make them look interesting. So it stands to reason that I’d be persnickety about how I go about that as well.

The popularity of filter-rich digital photos has shaped our cultural aesthetics. For people that view photography as more than just a break in the work day, I’ve decided to put together a sort of iPhone Photo Theory 101, detailing the processes I use nearly every day and the apps that make it possible. This page contains just shy of a bazillion photos, so… warnings for those of you on dial-up.

And I promise to go into more details than Marco Arment’s famous how-to.

Acquire

Camera.app

iPhoneography 101: Get great photos, and great control in iOSiOS 5 has made access to the built-in Camera.app quick and easy. Often, this is a fine enough place to capture images quickly. The built-in HDR functionality gives you a little better image to work with (sometimes). Usually, though, I have the time to take a controlled image. When possible, I use other apps to acquire my image.

An aside about RAW

Most DSLRs on the market offer the ability to shoot in a RAW format. By “raw”, the manufacturer means that all data collected by the photosensor is saved into the file.

iPhoneography 101: Get great photos, and great control in iOSMost digital photos go through two steps before they are committed to storage — processing and compression. Processing is typically determined by your camera’s settings (like white balance, exposure, etc.). Your camera may have different compression level settings, but most cameras use JPEG-type compression. The resulting image is much smaller with often little discernible difference in quality.

You can achieve a great large, lightly compressed JPEG image with most digital cameras. So why use RAW? Raw images are especially helpful when you plan on really manipulating the colors and light values in an image. It gives you the most data possible, comparable to what the film world (literal celluloid film, darkroom processing, Ansel Adams types) might refer to as a “thick” negative.

While you can certainly take RAW images with your DSLR and import them with the affordable iPad/iPhone camera connection kit (and process using an app such as PhotoRaw for iOS), there’s no way to get raw data from the iPhone camera, nor would you probably want to.

But there are ways to cheat, ways to get a rich image with which to begin.

ProHDR

ProHDR is without a doubt the camera app that I use most. It allows me to take a manually controlled couple of photos, which the app then aligns, merges, and tonemaps based on its built-in algorithm. It often gives me a great image straight out of the box, but being the control freak that I am, I will usually mess with the controls a little bit to get what I feel is the best starting point.

A good “thick” image may actually not look like a great photo. It will be milky and low contrast, though it might be fairly saturated color-wise. The aim is to make sure not to push or pull anything too far so you have plenty of room to play later down the path.

Camera+

The downfall of ProHDR is that while I can have manual control over where I expose my two photos, it still uses the built-in camera in all its automatic, untamed glory.

Occasionally, I will incorporate Camera+ into the mix. This gives me the control to focus on one spot while using another area of the image for exposure. The added ability to lock white balance is a feature critical for photos outdoors or in mixed lighting scenarios.

In the screen caps above, the box is the focal point and the aperture circle is the point of exposure. Note that white balance (WB) is unlocked.
Consider this photo of Bald River Falls that I took on a recent fishing trip. The falls itself is in deep shadow, while the ambient sunlight bouncing off the blue sky has gone super-blue. The composition is nicely framed with some foreground objects backlit by the much warmer light of a powerful, mid-afternoon sun.

iPhoneography 101: Get great photos, and great control in iOS
Using Camera.app or ProHDR, the camera will white balance to the focal point, sometimes making it hard for ProHDR to align and tonemap the two images together properly, resulting in a poor HDR photo. By using the manual functions of Camera+, I can choose a focal point to achieve my desired colors, lock the white balance, then manually focus.

With focus and white balance locked, I take two photos of differing exposure levels to get the widest range possible of image data.

Satisfied with the two photos I’ve taken (one dark, one light), I use ProHDR to import, align, and merge. With practice and patience, the results can be pretty stunning.

iPhoneography 101: Get great photos, and great control in iOS
I have to be careful not to choose places that are too drastically exposed or to move around too much between photos, or I’ll have some ghosting problems when ProHDR gets a hold of them. You can see some ghosting to the left of the falls in the final.

iPhoneography 101: Get great photos, and great control in iOS
“Ghosting” occurs when the HDR software has problems aligning,
often due to insufficient overlapping data from the two source images.

Some options

Owle Bubo + Canon lens adapter

iPhoneography 101: Get great photos, and great control in iOSIf you want to get super fancy, you can get the Owle Bubo to snap onto your iPhone. An optional lens connector (for Canon or Nikon lenses) from EnCinema gives you near-DSLR power. The combo, however, approaches the price of a low-level Canon or Nikon, so unless you plan on shooting some movies with your iPhone, your money may be better spent on a DSLR body with a kit lens.

AutoStitch Panorama

You can make some great panoramas out of your images by using AutoStitch. I’ve found it’s better to AutoStitch your unfiltered bright and dark images before importing the resulting panoramas into ProHDR, but it’s tough work. The photos need to be the same size (resolution) and should end up with roughly identical fields of view. But if you have the time to play with it and get it right, the results can be really great.

iPhoneography 101: Get great photos, and great control in iOS
Note: Beware of panoramas TOO large for your image editing app.

Editing your photos

Once you’ve acquired a beautiful image with which to start, the real work begins. While there are a number of photo editing apps available for iOS, the one I have fallen in love with is Photoforge2 from GhostBird Software. (I’ve written about it before, here.)

Aspect ratio

The shape of your photo may seem like a simple thing, but it can often have a subtle psychological effect on the viewer. Usually, my photos end up the same size as they were acquired. But every now and then, I’ll crop it for one reason or another.

A common reason is to crop out unwanted areas of the image. But among the cropping options in Photoforge2 are various locked-in aspect ratios. The two I use most commonly are 16:9 and 1:1.

iPhoneography 101: Get great photos, and great control in iOSThe 1:1 or square aspect has obviously been part of photography for ages, but it has recently been re-popularized by Instagram. Of course, it first came to pop culture through the Polaroid camera, and the retrophile culture loves to throw back their photos with this simple adjustment. The square shape intimates a moment frozen in time for posterity, something from the past worth holding on to.

Because most photos we see all day are rectangles, the square look also instantly brings a retro-hip neo-tech air to your photo. In my opinion, getting a good composition in a square aspect is very difficult, but if achieved, it can be very powerful.

The 16:9 ratio has, of course, been established by widescreen digital television. And though 16:9 (or 1.78:1) is a relatively new widescreen format for motion pictures, using this preset is a quick way to bring a cinematic feel to your shot. Many compositions fit nicely in the 16:9 cropping, and with the right treatment, your photo can feel like a still from some movie we’d all like to see. This subtle adjustment can give your viewer the sense of a captured moment from a larger scene.

iPhoneography 101: Get great photos, and great control in iOS
Whereas the 1:1 freezes and captures a single instant, the 16:9 ratio can intimate a longer period of time at which we’re momentarily privileged a mere glimpse.

(…maybe I’m thinking too much about this.)

Layers

One of the most powerful aspects of any photo-editing application is the ability to use layers as a non-destructive way to edit your photos. Photoforge2’s layer support is surprisingly robust.

With masking, blend modes, and opacity controls, most of the things for which you’d use layers in a pro-app like Photoshop are available to you in Photoforge2. I’ll share some practical uses of layers along the way.

Curves and other controls

I prefer the look of older film stocks (which these days would be ALL film stocks, I guess). From studying old photos that have been digitized and from the guidance of much more talented colorists than I, I’ve learned a bit about the way the old stocks (negative and print) took light. I use this knowledge a lot for my films, but I bring the same sensibilities to my personal photos.

While there have been great advancements in digital photo technology, no one has really captured the filmic curve. So no matter how the image is acquired (even with an expensive DSLR), my first adjustment is to take my thickened negative and give it a filmic coloring.

Sometimes this is just a subtle adjustment, but often I want to bring some nostalgia and timelessness to the photo. The other day, my mother remarked that a photo I sent her “looks like something from an old calendar”. I considered this a high complement. Just looking at the photo immediately took her mind to something from the past — timelessness achieved!

iPhoneography 101: Get great photos, and great control in iOS
While there’s not really a magic Coke formula for my curving, I generally add some reds to the blacks, take the whites a little yellowish, leave blue in the middle, and kill green from everywhere but the top. Then I roll off the top a little easier, crunch the bottom end to black, lower the high-mids, and bring up the low-mids.

iPhoneography 101: Get great photos, and great control in iOS
This will generally give a more filmic look, but you have to be careful with the adjustments as the digitally processed and compressed photos will thin quickly. How do you know if you’ve achieved the look? To repurpose a Ray Charles quote, “what does it look like, baby?” You’ll know it when you see it.

Photoforge2 also offers a lot of controls that I sometimes use later in the process, including Hue/Sat, Levels, Vibrance, Noise removal, and more. We’re talking almost Photoshop level control out of an app that costs $4.99 (on sale at the time of this posting for $2.99!!!).

Vignettes and other effects

Apart from the various image controls, Photoforge2 offers up some built-in effects, most of which I don’t use.

iPhoneography 101: Get great photos, and great control in iOSI do make a lot of use of the vignette feature, though. I often layer multiple, very light vignettes as a way of highlighting a focal point. Even greater control may be achieved by using layers and masking, but painting a mask with Photoforge2 is kinda clunky, especially on the iPhone. (If GhostBird Software ever adds in a Gradient painter, the layer mask would be the better way to go.)

Layers and masks are pretty useful for blurring vignettes. I don’t use them often, but it’s really the only way to make that happen. Dupe the layer, add a Gaussian blur, add a mask, and fingerpaint with concentric shapes from black to white (transparent to opaque) to get close to what you want.

iPhoneography 101: Get great photos, and great control in iOS
iPhoneography 101: Get great photos, and great control in iOSThe only other filter option I make use of is the PopCam! Fx, an in-app purchase for $1.99. This gives you some Hipstamatic-type controls (choose a lens, filmstock, flash, etc.), and I will occasionally see if something in there can punch up my photo in a way I haven’t thought of yet. While the filters are many, there’s little control to them; it’s basically filter on or filter off.

Textures

One interesting feature of the PopCam! FX is the ability to add textures to your photos. Especially if you’re going for an old photo look, this can be a neat way to color, stain, or grunge up your photo. But the developers have given you even more control over this functionality in the Photo Properties pop-up. Choose a built-in texture and choose a blend mode and opacity level.

iPhoneography 101: Get great photos, and great control in iOSiPhoneography 101: Get great photos, and great control in iOS
Still, this isn’t enough control for me! So I often add a color layer to my project, then apply a texture to that layer using a multiply mode. With a texture layer created, I change the blend mode of that layer to Multiply or Overlay and adjust the opacity to get the desired texturing.

For real pro-control, you can download lots of free grunge textures online and make an iPhoto album of them. Instead of adding a blank layer and applying a built-in texture, you can load in one of these photos as your texture layer.

Curation

Cleaning up your Camera Roll

Having your photo go through multiple stages is great for your photo, but makes a mess out of your Camera Roll. iOS 5 gives you the ability to create photo albums so you can quickly locate your selects. When you go to clean up your camera roll, Photos.app will let you know if one of the images you’ve selected for deletion has been put into an album.

iPhoneography 101: Get great photos, and great control in iOS
Of course, a better option is to offload them to iPhoto or Aperture next time you’re connected to your Mac. Once you’re sure you’ve moved everything to your Mac, cleaning your camera roll is a lot less scary.

Note that Photoforge2 projects are BIG. I’ve filled up my 32GB iPhone with them more than once. Once I’ve created my final image, I will usually delete the Photoforge2 project. The only reason for keeping the project is if I think I might tweak the photo some more or if I particularly like the overlays and textures. I can open the project, create a new layer above the base layer by importing another image to give it the same treatment as the original.

Photo Stream could be another way to back up the photos in your camera roll. While these methods make for a messy camera roll (and therefore a messy, un-editable Photo Stream), it’s good for snapping pictures on your iPhone, then using your iPad for Photoforge2.

Catalog and Share

iPhoneography 101: Get great photos, and great control in iOSWhile you can catalog your photos on your Mac using iPhoto or Aperture, Photoforge2 allows you to export to a number of online options such as Twitter, Facebook albums, flickr, Picasa, tumblr, and Dropbox.

iPhoneography 101: Get great photos, and great control in iOSI use Photo365 to remind me to take a picture every day. Even though I’ve missed a few days, it’s made a nice visual journal, reminding me of where I was and what I was doing on a given date. It also exports to Twitter, Facebook, and flickr.

If you’ve amassed some really great photos, a cool way to share them with family or friends is as a gift. iPhoto allows you to create coffee table books of your photos. A number of online sites, such as CanvasPeople, will put your photos on canvas for a reasonable price, turning your pocket hobby into a gallery masterpiece.

The new iOS Cards.app allows you to send custom greeting cards using photos from your iPhone’s Camera Album. While I initially rolled my eyes at the Cards app when it was announced, I’ve used it several times. It’s a great way for a hi-tech geek who doesn’t even use pen and paper any more (like me) to connect with someone who still has an appreciation for a personal paper card in the mailbox (like my mom).

Conclusion

This is a ton of info about what should be a simple process of snapping a camera phone pic and showing it to people. While I’ve gone into a great bit of detail, realize that I rarely spend more than a few minutes doctoring these pictures. Sometimes I do it on the spot, sometimes I do it while conversing with my travel companions, and sometimes I’ll use it as a way to wind down in the evening before bed.

The key is to find out what resources are available to you, use them often, and do not fear adding to the complexity of your process.

And what’s more? The total current cost of every iOS app I’ve mentioned in this article is $19.94 (and over half of that is just for PhotoRAW). Head to the links below to learn more.
