Learn the basics of using your speedlight to take your photography to the next level. There are bounce flash, straight forward flash, TTL daytime flash just as your basics before jumping into strobe and off camera flash.
I will also recommend my favorite flash speedlight for your Nikon, Canon, Sony or Fujifilm camera and gives few reasons why. I highlight recommend Godox V1 and Flashpoint R2 speedlights over any speedlight and even over the Nikon, Canon, Sony and Fujufilm brand speedlight flashes! They are great quality, tough build, works with each other with transmitter, has HSS and more.
