The worst photo shoot I ever attempted was a shoot of my family, including myself using a self-timer, which was to be used as Christmas gifts for other family members. By the end of the shoot, I really thought about murdering my children and leaving my wife. These were the worst photos I have ever shot and the stress involved in trying to get a decent shot of all of us, is something that no human should ever have to endure.
My kids and I look back on it now and laugh, but I can assure you that at the time, it was no laughing matter.
Thanks for the link.
