Hi all, I am fairly new to the external flash. I have the Altura from amazon on my Nikon D3200. I decided to get a 35mm lens and am trying to figure out how to work with different apertures better as well. Since I have been looking into this so much and learning what each mode is on the flash, I noticed that my external flash on “TTL” mode should automatically link to my camera settings and show up on the screen. Unfortunately it seems it is not connecting and only reads “TTL” on the external flash screen. Wondering if i need to maybe change some settings in my camera so it will sync ? TIA.
