Have you considered photography software for your food photography? As mentioned in my previous article I use a combination of iPhone 5 with filters and a Canon SLR for my food photography.
The SLR demands I use an SD card to store my photos, which I can then take out of the camera and plug into a computer for photo editing. Some cameras come with the brand's own photo editing software. But I don't use this.
Recently I was privileged to attend a Canon Photography Class at Taste of Melbourne where I was taken around by expert Canon Photographers to learn more about food photography.
It was heaps of fun not only learning from these guys who have travelled the world taking photographs, but to see Taste of Melbourne through the lens of a Canon EOS 5D mark III.
