Re: Contest 82: Put the glass on the table
Excuse me for another: I wanted to "revisit" just the glass with its at least 4 different areas of opacity and set aside the art portion of this challenge.  |

That's the funniest thing I've read all day. LOVE the Sponge Bob. Thanks for the entertainment. |

Re: Contest 82: Put the glass on the table
Well, I warned you this would be a tricky one! How many of you, I wonder, studied a glass of water to see how the reflections and refractions actually work? Mguyer started things off with a good stab at this one. The refraction's excellent, but I'm not sure about the blurring: the image through the glass should be as sharp as a view through a lens, since that's effectively what it is. But althought the end result is a little fuzzy, there are some good techniques here. The addition of a couple of bottles of scotch in the second entry does liven things up, though. A great entry from kenney added ice cubes and a pale whisky colouring - very neat touch, that - with some fine refraction through the top of the glass, as well as a good shadow beneath it. And the second entry is just fantastic - especially the water on the table surface. Oh, and of course the drunken sot in the background! Looks like it could be a good entry from Robbie, but it's really too small to see. Robbie, I always post the high res images separately - they're linked in the introductory text each week. Use these instead! Welcome to yuvalbra, with some great translucency in the glass. The refraction is a litle hard-edged, though - and it appears to show a tiny impression of the glass itself within it! Some mistake here, perhaps? But a great first entry - welcome to the forum! We look forward to seeing more of your work. A thoroughly entertaining piece from Eggbox, with a perfect packet of painkillers and a beautiful shine on the edge of the glass, reflecting down onto the table. Placing the glass so far into the middle of the table neatly avoids the refraction issue, too - a damn fine Cheat! I really enjoyed jimt's black and white entry, with a choking figure who has a hyper real quality to him. Is he heavily retouched? Or does he naturally have surprisingly smooth skin? I really want to know more about this one! Lighting direction proved to be a problem for many of you, as chris discovered. Great refraction, and a reasonably convincing shadow - but there's something about the shape of the shadow that doesn't quite work. This is a really tricky one to get right, and it was a valiant attempt: I think perhaps the shadow should be skewed in the other direction, so the left edge sticks out further than the top (right) edge? Very entertaining second entry - I love the idea of wearing a diving mask to talk to the fish. Oh, and the shadow of the fish in the glass is great! Some good refraction again from Lexus, and the addition of the ice cubes helps this one a lot. Stretching the glass vertically has made the base a little out of perspective with the table, though: the shape of the ellipse of the bottom of the glass should match that of the table, ideally. And, maybe, a bit more sparkle needed here. Welcome, also, to amy3515, with another tiny entry: as I said above, use the full size images rather than the small previews to work on! Hard to see exactly what's going on here; the only comment I can make is that the shadow seems a little harsh. In cases like this, don't paint the shadow on: instead, use a copy of the glass itself, set to Multiply mode, to create a perfect impression. A fine piece of whimsy from mr.pbody, with Hendrix getting into a purple funk. Not sure about the message here, ut a couple of comments: the dress of the woman needs to be more translucent in front of the table (try the Background Eraser at a low setting), and her husband really should either go on a diet or buy a chair the right size for him! Some beautiful applique work from Tom, with a decorated glass filled with some kind of blackcurrant cordial. Or is that Cinzano, a throwback to the 70s? Excellent refraction, a fantastic window reflection on the glass, and some really neat touches - the telephone on the chair, the graffiti on the table, and the greatly improved table surface. Great work! Superb refraction, and a great indication of the water surface in G. E. Sutton's post - but I'm not sure about those shadows. Surely they should darken the table surface, rather than lightening it? Beautiful glass texture, great shine overall. More ice in pauline's entry, with just the hint of refraction at the very top of the glass. The shadow very nearly works, Pauline: but perhaps you need to make it refract through the glass as well? Top marks to Whaler for being the only one to attempt to reflect the scene in the table. A lovely job, with a great, crisp glass. A couple of things, though: shouldn't the glass be casting a reflection as well? And does the extreme rippling in the surface of the water signify an impending earthquake? And welcome, also, to lawrenceging. Once again, Lawrence, take note of the fact that high res images are linked in the introductory text! Looks like some really good refraction going on in the glass, but it's too small to be able to see it clearly. I suspect, however, that it's a really well executed job. Welcome to the forum! Our fourth new member this week - we must be doing something right! Bob has given us a fantastic piece of work, with a great sense of transparency to the glass and a neatly flipped refraction. Like the drinks coaster, too - a very nice touch. The glass surface looks just right - but I'd have added a little refraction through the empty part of the glass as well. All told, though, this is a beautiful job - thanks for joining! The best reflections of the week award goes to Neal, not just for the room reflected in the glass, but the reflection of the glass on the table, too. Except - er - flipping the glass vertically to make its reflection still has it curving the wrong way. I know you don't have CS2, Neal, but a rotate and quick application of the Shear filter would have sorted this one out. There's plenty of great stuff going on in DaltonX's entry - loads of props, a great splash on the table, ice and a cocktail stick in the glass, reflections on the table, and more. I particularly like the way the rim of the glass has its own refraction - superb attention to detail, there. Beautiful work, and highly entertaining! Plenty more wildlife from jwhite - I especially like the idea of turning that drinks cabinet into a TV. The curious figure on the chair and the lizard on the drinks table work well, but I'd like to have seen a shadow under that panda! The glass itself is a little dull-looking: perhaps the frog needs its water changed? There's some good refraction in Dek101's entry, but the glass itself seems a little ghostly. Perhaps add an extra layer set to Hard Light mode to give this one some clarity? This has been the hardest Friday Challenge for some time, and has produced some excellent results. The trick is to separate the glass into its constituent parts - the water-filled area, the empty glass above, and the rim - and fill each area with different degrees of distorted background. Then, placing a copy of the glass on top at, say Hard Light or Overlay mode to bring some definition back should help to do the trick. The shadow is, of course, best made as a copy of the glass set to Multiply mode, and distorted to lie flat along the surface of the table. So what should all those refractions really look like? Rather than attempt to mock this one up, I held a glass of water in front of the original image on my monitor and photographed that. Here's the result: 
As you can see, the water-filled area distorts the view to a very large extent; the surface reflects the view, but also refracts the scene through the bottom of the glass; the clear area also distorts the view, but to a lesser extent - and it's accentuated at the edges, where the light has to travel through a much greater thickness of glass before it reaches us. Well done, everyone. And it's fantastic to meet so many new members! Keep coming back! |

Re: Contest 82: Put the glass on the table
Thanks Steve for your crit. I first thought the glass might have inverted or reversed the image untill I looked at my room through a glass of water. Is it still a damn fine cheat not to have drawn the box of pills from scratch but to have photographed it? Ted |

Re: Contest 82: Put the glass on the table
Thanx for the comments Steve.... and that was a great idea to take a pic of a glass in front of the monitor.... I originally took a pic of a glass of water on a table myself, which let me see the reflections and refractions ..... but I didn't quite match the angle right... so it didn't really work properly..... never thought of doing wut you did... very clever indeed

Re: Contest 82: Put the glass on the table
thanks, Steve, your comments are as always to the point and appreciated. As far as the rippling goes, I had Jurassic Park in mind and was kind of expecting you and others to comment on that. |

Re: Contest 82: Put the glass on the table
Yes, I was not happy with those shadows, but couldn't put my finger on it; I wanted there to be some bright spots due to the lens effect. When I saw Bob's entry I could see he nailed what I was trying to achieve. |

Learned something new again! Never thought of trying to make the shadow refract through the glass. _________________ Pauline |

Thanks for commenting Steve. Interesting how the couch or chair shows in the actual photo of the glass. I'm glad this wallpaper is not permanent.  |

It'll be gone next Friday. Possibly before, if everyone gets sick of it. Making me a little nauseous already. |
