Resubmittal...turned the glass a bit to the blue scale and added a bit of glass to connect the stem to the bowl.

Hmmm?

And what about the shape of that reflection? I'm pretty much stumped on it.

Well Mark for good measure I set up a wine glass a cork, and guess what...I didn't see any reflections of the cork in the wine glass. Well there was a very small speck, but basically nothing. Now objects at bowl level or higher did show more of a reflection than those below it.

I played around quickly with the photo and came up with this….but it still doesn't seem right.

I could be easily convinced that a cork casts no such reflection.

I've done a little work on the highlights and shadows and I'm calling this one "done". Here is a final repost.

Thanks for all the help folks. Now I don't know aobut you, but I'm ready to move on. :-)

Not on a par with the other images here but I thought I'd post it anyway.

Started with an outline of the glass shape, used motion blur to soften the outline then smudged in the shading. Duplicated and did different layer blends to get the final result.

Not on par huh....Christine this is not a competition or comparision so please never hesitate to submit something. This site is about learning and sharing techniques so all levels are welcomed.

While your image might not be a true photorealistic image, it has a nice arty quailty. I especially like the smudging of the shadows and highlights. Very nice results! When you say you worked from an outline, did you take a photo and use it as a tracing source or did you create the outline by hand?

Kudos on your entry and I hope to see more.

I just drew the outline using a glass for reference.

Very nicely done! I need to use things as a reference as well. I'm not as strong drawing images from my head...need to see something to really create an accurate drawing. You should give some of the other challenges a try, hint, hint.

I agree this is a well drawn figure. You've got the outline and shape looking very good. I think that in the interest of "photorealism" it might be improved a bit.

The glass that makes up the object looks really thick. The line that defines the rim of the glass looks very heavy. Also, the highlights and shadows appear to be roughly the right shape and in the right locations. As drawn figures they are fine, but would they look more natural if they were actually produced with gradients and burning/dodging over a 50% gray layer?

Again, I think this is a fine looking figure. You've done a truly wonderful job of rendering the shape and roughing in the highlights and shadows that seem to be the key to making these transparent things. It would thrill me to see you get it looking like a transparent 3D object. How about reposting it with a much lighter line defining the rim?

Just curious.

Mark

Christine,

Mark has some good suggestions. The dark band around the top of the glass doesn't bother me however, as it could be coloring added to the glass. I have a parfait glass that looks exactly like this except that the band is gold. I do agree that the rim as well as the base could be a little thinner in thickness.

I’d love you to try Mark's suggestions as your image is almost there. You just need to soften up the rough edges and work on adding a bit more transparency.

Keep up the good work!

Good point T. Making that black line a cleverly highlighted/shadowed gold gradient would look spiffy. It might also improve realism in this case. I'd love to see it.
