For things larger than scanners, what is the optimal way to photograph large paintings? I'm having a severe problem getting good photos of my stuff, which these days is WAY larger than my scanner plate. I have a really old digital camera, but for the most part it usually does the job... however I just can't get a good photo of artwork

Is it my lighting? Is it really my camera? I am too lazy to go get my camera so I don't know the specs, but.... yeah. Help?
That's why there's no posts, can't get good photos

Sowwy.
Also, commissions. Still doing them, just don't feel like copying and pasting my list everytime I make a new journal.
