Use your iPhone or iPod touch to provide a label, title or banner for your photos.
Either position your iPhone alongside the subject of your photograph, or take a photo of the iPhone screen before and/or after taking the shot.
This helps supplement the date information provided on your camera, which can be helpful after a long day of shooting. I have found this very useful when taking pictures of flowers, and when making a catalogue of items for insurance purposes.
The app includes title, subtitle, optional date and time, optional index counter and optional bar for correcting the colours of your images later.
