Yeah, it is way harder than I am used to! Thanks, I was having fun with the lighting that day. The YN560 IV's are insanely good for the price. I have had them for like three years and have not treated them kindly but they still just keep firing away. The built in radio slaves are a massive bonus, I just use them with the RF602 triggers from Yongnuo and it is a piece of cake. If you are a manual flash shooter there is literally no reason to go with anything else, they are by far the cheapest, and in my experience they work like a charm every time. Well worth the (minimal) investment!!
