I really loved David Loftus’s recent Food Photography Masterclass series on Jamie Oliver’s FoodTube. So much useful information and handy tips on improving your photography, creating your own reflectors and food styling. As well as information on lighting, depth of field and other ‘basics’ for DSLR photography.
I made this handy playlist of them all so I would have them all in one handy place.
If you want to improve your photography, I highly recommend this series.
