Keleko, definitely paying for the photography tour is worth it. I used Antelope Canyon Tours. Obviously, a tripod and a wide angle lens are musts. Bring only one lens or two cameras if you want to bring a second lens. Too much dust puts sensors at risk if changing lenses while in there. I did Upper Canyon. Lower canyon does NOT allow tripods and has ladder steps to climb up and down and my knees told me not to go there! But I'm an old fart. My wife went on the regular tour while I took Photography tour #2. It lasts longer and is solely for serious photographers. Any other questions PM me. Oh, Horseshoe Bend is under construction so during the day you have to take a bus there but after 6PM you can go there and park for sunset shots. The buses stop at 6PM and run every half hour.
