You never know what you'll run into during a photo session, which is why i have my bag stocked with my gear and other supplies to ensure there is never a problem!
I always travel with two camera bodies. I have my Nikon D750 (my pride and joy) and my Nikon D5600. My absolute, hands down favorite portrait lens is my 85mm. I also have in my bag my 50mm, 24-120mm, 70-300mm, and my macro lens. I need extra lighting in some settings, so I have my off-camera flash with a beauty dish and trigger.
What else do I have you might ask?
Especially for my brides, i have a small kit filled with bobby pins, safety pins, and needle and thread. I have bandages, mints, gum, tylenol, etc. You name it!
You never know when you'll need a quick beauty fix last second, and I've got you covered!
All of my gear is stored in my precious, leather House of Flynn Evermore Camera Bag. It is absolutely beautiful and has plenty of room for all my gear.
