Well, I feel a little bit better about it...I felt like sometimes, for some things, you guys have to drag me along, knowing full well I don't fully understand what you're doing. My pastor many years ago taught me the basics of computers...he could do programming, and had a degree in math which enabled him to teach at college level, so he knew his stuff. I became like a daughter to him, and he made it his business to make me learn the basics of computers, or he felt I would be unable to keep up in a professional environment. Boy was he right. My peers and co-workers in my age group were poo-pooing the whole idea, but I stuffed the information in my head, best I could. In some respects, I suppose he was my private tutor...I just never thought of it that way. Anyway, I was more than prepared for the challenges I had to face, even years later, in the work place....and I was still amazed, at the time I retired, at the level of inexperience of folks who supposedly had IT degrees...simple things like not being able to dig around on a hard drive to find folders just to place a shortcut to it on the desktop....didn't have a clue, and I was called to come show them...I truly felt like a fool for the guy, and couldn't help but be amazed at the humor and irony. I was literally having to train college grads when I prepared for my retirement.
Back to 3D....I don't have the advantage of having had "private tutoring" to get me up and running, so I've had to take learning in snippets. Once I hear something explained in a step by step, logical fashion, usually I can figure the rest out. It's when the information comes at me backwards, least important first, that I get overwhelmed, since I have no way on my own, no point of reference, to distinguish what's critical and necessary from what can wait, or will come in time with experience. When I was helping Sarah, that presented its own challenges since she was not just slightly, but seriously dyslexic....brilliant as she could be, but she had a problem not only with visual disorder, but also her thought processes would get "snags" too....she'd send three page emails to me attempting to explain some simple thing she'd learned that day, and I had to learn how to discern the bottom line. So I had not only my own drop off points, but hers as well. That's why I started the beginner PDF tutorials in just about everything at the time...it was to help her re-order her thinking process to follow simple illustrated steps...and it worked. I had to learn the basics so that I could interpret them for her. Since she passed in 2011, and then my retirement from work in 2012, my focus in 3D has been primarily posing...like my comfort zone I guess.
I do lighting the way you just described....sun is coming from this side, so shadows have to be here, or there. I know it isn't "right", but it's okay...especially for pose set promos....they can be not very good, according to what I've seen out there...haha.
If my health had not gotten onto a slippery slope, I'd probably have irons in every 3D fire by now, learning as much as I could. I did the same thing with music....taught myself six different instruments, and had the same challenges with folks with music degrees...they couldn't understand how I could anticipate what they were going to play before they played it, and they'd sorta be offended that I could do it...haha. It wasn't until I joined with friends who were black in a band that I felt "at home"...they spoke my musical language and we got along beautifully, jammin' ourselves silly. That's kinda how it needs to be in 3D...to find those who speak your language. I think that's why I like your tutorials so much Seliah...because they make sense to me.
