Hi, I'm testing out a Canon EOS 7D and trying to come up with settings to achieve a pure white background for product shots using a pair of fluorescent lights in 24" soft boxes and a white vinyl background. On my existing Canon, I used the P mode, a high fluorescent WB setting and a variety of different setting tweaks to do so. I've been playing about with the settings but haven't found anything super yet. Can anyone suggest some basic settings that I could try to work off of for most products? If I had a good starting points I could adjust as needed depending on the product.
