Some time ago Adrian explained how to colour pop on the PC. Today I happened to come across Color Splash, an app for the iPad which does the job so easily I couldn't resist investing the £1.50 or so. In fact it was more trouble finding out how to transfer the results from the iPad to the PC than it was to go a popping.
It took well under an hour to achieve the above results, including the time to download and install the app and searching for help to transfer the results to the PC. No other processing was used and no wildlife was harmed in the process.
