Good morning. I am using Nikon's D850 to shoot my son's youth basketball league. They play indoors, with very high ceilings and iridescent lighting. The gym uses normal lights, and generally the lighting is very open inside the gym. However, I am struggling to find the right settings to catch my son in an action shot without having everything in focus. I've gone up on my ISO to 1600, opened my aperature wide, and then came back narrow, changed white balance settings numerous times, changed metering modes (back to matrix now), and experimented with different focus settings. I am shooting in RAW, and have the extra vertical grip along with the Nikon EN-EL18b battery, so still can't figure out why my shots are not focusing when in action. I've tried to shoot around 1/1000 in shutter priority, every photo is still out of focus - primarily the basketball itself while in air. I'll post an image to demonstrate the challenges I'm having. I will gladly take any recommendations from anyone in these forums to have better results. Thanks for reading, and thank you in advance for any feedback!!
