Thank you . There's no doubt it's easier to hold a phone vertically. I've got a fairly high-end camera* but that one was actually taken with my phone since I pretty much always have it with me, I've got a phone holster rigged up that I snap to a belt loop.Beautiful butterfly! I do the same. I think it's because I use a camera and not my phone most of the time. If I'm using my phone I tend to take more portrait photos.
*Well, high-end for me anyway.
