AITA for taking pictures of horse cock with my new camera?

I (30m) on my 30 birthday I got an new expensive camera from my dying grandparents. So I decided take pictures of their horses since they weren’t going to see them soon. While taking pictures of their gracious bodies I seemed to slip on this sticky stuff on the floor. On the ground I was able to take pictures of their giant cock, I got carried away and started taking multiple pictures maybe 30 not a lot well not enough. I then showed them to my dying grandparents and they were furious (I don’t know why).

Word got out and they said they were cutting me out of the will. So now my wife and family members know. My wife of 6 years is saying she going to divorce me and my family members have cut all contact. I don’t think i did anything wrong, just showing my grandparents the most interesting part of the horses. Anyway now everyone hates me so Reddit AITA for showing my dying grandparents 4k horse cock?

Edit: So i’ve read some comments saying I’m not TA (downvoted for some reason) and haves taken their advice and take pictures of their ass instead.
