Flickr’s new iPhone App
It combines Flickr's great sharing & viewing functionality with a fairly solid camera application (following hot on Twitter's heels, using the SDK from the folks at Aviary).
It shoots at full iPhone size (2448 x 3264 pixels on the iPhone 5's main camera, above; 960 x 1280 pixels on the front facing camera, below).
Before you take the shot, you can take a light reading from one place, and focus on another (drag your fingers apart on your phone's screen to do that), set a background grid to straighten your shot, and zoom in (though that's an artificial zoom, you're really just cropping into the pixels).
Once you've taken your shot, before it's saved, the app lets you play around with some admittedly rather arbitrarily named filters, as well as make various adjustments: cropping, brightness, contrast, saturation and sharpness. You can also add some very basic text, do some basic drawing, add brightness and fix blemishes. All of that while keeping the image at full size (though you can set it to be smaller in the settings if you want).
Once you're done editing, you upload the image (it only saves to the camera roll at this point, which speeds things up, but can lead to you thinking you've saved a shot that you haven't).
You can upload directly to Flickr of course, with all your tags in place, and send it to all the Groups and Sets you fancy at the same time. Rather neatly, at the same time as it loads to Flickr, you can send the image to Twitter (works well on the native app, but not at all on a third party app like TweetDeck) and Facebook (the images are hi-res, and dumped into a Flickr Photos album on your page).
Once you've finished shooting, you can do all the browsing you'd expect too - that's Alistair's Signs and lettering set below.
Good work Flickr.
