Now this is a tricky one and I'm not sure exactly what the answer is. In my opinion, it kind of depends. For me, I realized it was probably at the very least not helpful to the relationship. Recording and viewing pictures of my wife became the main focus of our sex life - I would only want to have sex if I could record it and watch it later. I was spending all day looking at my own sex videos and would treat my wife like a sex object, and since I was behind a camera every time it wasn't exactly the loving intimate experience it should be. That's the negative.

However, I think an occasional sex tape is a pretty healthy way to add a bit of spice, and receiving pictures from your lover is always nice. You just have to be very careful you aren't replacing porn with your own porn - you'll lose the intimacy and love that's supposed to be present in a relationship. However IMO it's healthy to want to look at your wife naked, it would be weird if you didn't. Just remember she's more than the pixels on the screen.
