It really use to not be. I've got studio lights that use $70 bulbs and they last about 100 hours each. Nowadays you can get florescent lighting for nothing and they last forever.
I have a friend who serves on the audio visual team with me at church who has offered to help me in the future if I need help. He does a lot of camera work, making movies, etc... Yeah, he was saying that nowadays, lighting can be pretty inexpensive. Over time, especially if I start making decent money from it, then I'll upgrade as I go along. My wife, who has been a professional photographer in the past (now mainly works with graphic design), has a backdrop, but it's huge! It's not something you could set up and tear down quickly. If I had a room that I could just leave it setup, I would do that, but as big as it is, we can't just leave it up in our spare bedroom, it would have to be setup in our living room. Maybe when warmer weather comes, I might be able to do some of this in our second garage.
I'm trying to come up with some content for this week. I really would like to release two videos a week in the beginning, but it can be challenging coming up with the time to put into it. Right now, I might be lucky if I can do one a week, which would wind up giving me around 50 videos, but it would take all year to do that. I want to make sure the content is good so I'm getting the views I need. Right now, I think my first video has gotten over 70 views, and the second had gotten over 40 views. That's not bad for one week. I'm also trying to join some Sleep Apnea forums in hopes of promoting on those sites, I just don't want to flood those sites and not participate like I should, but what better way to promote than to converse with those who actually do have Sleep Apnea?
