Okay! So I've been doing some learning/experimenting with texturing and lighting.
I've decided that these specific canisters are going to be a learning project, not part of the actual full 'kitchen project' I plan to do. I was doing some searching online and found some canisters whose look and style I like a lot more. More curvy, and with a blue and gray earthenware look. I think they'll be more interesting to look at.
So! I did some renders, experimenting with the different settings, but am finding that I can't get the light very bright. At 100% (255, 255, 255), and up close to the jars, it's just not very bright. I also didn't see a multiplier, or any mention in the documentation (though I might have overlooked it) on how to increase the brightness. Is there a way to increase the brightness of the lights? It's a spotlight. Also just realized I'd forgotten to enable shadows for that shot. Whoops.
So, here's a render I did.. There's the base diffuse color, a spec map (which isn't very noticeable in this shot) and an environment map applied.
