I have been shooting food for almost 30 years. In the old days, I used a 4 x 5 view camera, a fascinating yet complicated device which was the standard of the day. One had to view the image while hiding under a black cloth; to make matters worse, the image was upside down. Of course, it was film back then which required loading the 4 x 5 film holders in a darkroom and then bracketing (taking differently timed exposures) to make sure the image was exposed correctly. I eventually graduated to a Hasselblad which shoots squares that are much smaller than 4 x 5 images, but still much larger than the usual 35 mm image. Exposure was still a problem such that multiple exposures still had to be made. It was during the Hasselblad period that I switched to digital. Suddenly the exposure problems were gone such that I only had to focus on composition and lighting. Now, I use a Sony mirrorless camera, a marvel of modern sophistication in which you see exactly the image you're going to get.
