If, like me, you find Lightroom to be an essential piece of software, and if, like me you have an iPad, you may be interested in this.
LRPAD is an iPad app that lets you play with Lightroom’s numerous sliders. The app is available from the App Store, current price £5.99 (around $9.99 in the US, other prices elsewhere, no doubt). You also need to install a free plug-in into Lightroom, and your iPad needs to be on the same network as the computer (Windows or Mac) running Lightroom.
Once you’ve got the plug-in installed, you need to start the app on the iPad and type in the IP address of the computer (it can’t sniff for a running copy of Lightroom, which would make it slightly easier). You then get a nice touchy-feely interface for manipulating your images. Lean back in your chair and experiment.
I’ve had a quick play, and so far I’d say it’s a qualified success. Moving the sliders on the iPad makes the corresponding ones move in Lightroom, and makes the appropriate changes to the current image. However, there is a slight lag between moving a slider and the change taking place, so you’ll probably want to take things slowly at first.
I don’t know if I’ll use this a lot, but it has the potential to be very useful – more features are promised for future versions, which could make it more attractive.
More details including screenshots and a demo video on the developer’s site, along with a small support section.
Worth a look at the very least.
 Don’t think I mentioned that. I succumbed and got the WiFi only 16GB version, and find that I use it intermittently. Just enough to keep it, but not enough to consider upgrading to the imminent new version
