haha I'm glad you noticed I'm reading old posts! Sometimes I wonder "will they ever know I'm trying to talk to them if I comment on old stuff?" Newb question.
Wow, really. You're making me seriously think about it...if you work wonders like that with an entry level, I can't imagine what you'll do with an upgraded one.
There is a "replies" tab in the Steemit profile that notifies me of all replies ;)
Actually, the benefits of an expensive camera are not that significant; for shooting photos for the web, in most cases, you won't see a difference between a 500$ and a 5k$ camera. They can only play their advantages in low-light or when shooting high resolution for large prints, but they are less compact and less suitable for travel photography.
