Hipstamatic ($1.99)

Most iPhone users are familiar with this wonderful app. It offers several “film” types and lenses that distort in a colorful, exaggerated way. It’s fun and makes everyday snaps look artsy and retro. Some of the Instagram filters seem to mimic the look of Hipsta, but the real deal is still the king for funky street photography.

Old Photo Pro (free)

One of several apps that give images that faded photo print look. Not only does it give the pictures a weathered texture, but the edges also have a burned and damaged look.

ShakeItPhoto ($1.99)

One of many apps that simulate the shape and look of a Polaroid Instant photo, but taking it one step farther: When you click the shutter to take a photo, it actually makes the “click . . . whirrrrr” sound of an instant picture exiting the Polaroid camera. And if that’s not cute enough, you actually have to shake your phone back and forth for 30 seconds to develop the photo, just as in the old days. I like the old Polaroid look, but I’m still deciding whether I find it silly or clever that the designers went to all that trouble.

6x6 (99 cents)

I post to Instagram, Twitter and Facebook using the functionality of Instagram. But my preference is to take the original photograph using 6x6, which keeps the square Instagram dimension but doesn’t force me to process and upload immediately. It lets you shoot and automatically save to your Camera Roll. It also gives you the option of color or black-and-white, it offers a grid so that your horizons don’t tilt, it gives you the option of manual focus and exposure control, and if you prefer, it doesn’t add additional processing to your images.

Snapseed ($4.99)

This is one of my favorite apps and the most expensive one that I own. It’s robust and offers many ways to enhance, tone and manipulate images. The auto-correct option is a one-touch way to quickly add contrast/sharpening and vibrancy to any image. If you have more time, it offers pinpointed tone adjustments, cropping, sharpening, selective focus and additional options to grunge it up. If you’re familiar with photo-toning software for your computer, this app is similar in its robustness and options.

AutoStitch ($1.99)

Great for capturing panoramics of the settings around you. It’s easy to use, saves high-resolution images to the Camera Roll and offers the option to crop the final image. If you have a Facebook page, then you’ve seen pages with a panoramic image across the top. AutoStitch is the perfect app for creating an image for this design.

Diptic (99 cents)

Allows you to combine multiple photos into one image using any number of pre-loaded layouts. If you took three beautiful shots, consider combing them into one image and using each frame to highlight the different details that caught your eye. You don’t have to use separate pictures; you could use the same photo but zoom in on different details in each frame. With a little bit of creativity, you can use Diptic’s multiple frames to tell a story or show action the way a comic-book artist might. To use it, first select the layout you want, then tap each frame to load your photo. Zoom in by pinching or stretching the picture.
