I have taken photographs and processed them for over 60 years. In the early 1990s when I bought my first Photoshop program I had film images copied onto disk. Digital cameras began with Nikon 4500 then Pentax Optio X and now Canon 40D. In 2003 Windows PC was dropped in favour of Apple Mac where photography with Photoshop CS3 and Aperture 2 work superbly on a MacBook Pro with a portable SSDs. I use my iPhone 6+ camera in preference to other cameras except when I want to use telephoto. The iPhone 6 plus camera copes superbly with almost every subject, it is excellent in low light conditions and variable lighting conditions present very few problems.
