FX Photo Studio (iPhone | iPad) lets you edit images on your iPhone, add multiple effects, then add stylized text for a unique look. The app includes all the basic image-editing controls such as brightness, contrast, and color balance, along with cropping and rotation tools.
But where FX Photo Studio shines is in the amount you can do with your photos by selecting from an enormous number of effects. As of this writing, FX Photo Studio includes 190 high-quality effects you can add to your images. You can also combine effects for virtually limitless combinations. But while the app features a ton of effects, it doesn't have a live preview like many other photo-editing apps. Instead you can look at the different effects, pick one, then the app will show you your photo with the effect. To help this somewhat slow process, you can cycle through effects when you're looking at your image using the arrows at the top. Still, it's not an ideal workflow.
Get started by either taking a picture with your iPhone camera or picking one from your photo library. From there the app defaults to showing you its entire list of 190 effects with a standardized preview photo to give you an idea what you're getting as you browse through each. With so many effects, it can be overwhelming, but fortunately you can also view effects in category folders, which makes it a little easier to find what you want. If you find an effect you really like, you can touch a star-shaped button to add it to your favorites list.
A couple of features let you create a mask on your photo for mixed effects. For the color-splash look, you can start with a gray scale photo, then splash color only on the parts you want. The color-splash button changes your photo to gray scale automatically, then lets you paint a mask with your finger to bring out the original color where you touch. You can do the same with filters. With a filter selected, you can touch the paint brush button in the lower right, then paint the filter only on the parts of the image you want. Other apps have similar features, but with FX Photo Studio, you can make the mask, then layer more effects on top of your work for some really interesting projects.
