    Etched Glass

    This is actually a -very- hard thing to get right. This was for a client of mine who allowed me permission to post this. The etchings are a procedural bump texture with an ever so slight irradiance/opacity map to really bring out the etch lines.

    HDRI lighting and caustic refraction elements were used for reflections, as well as ambient occlusive dithering, and of course, depth of field lol.

        Is it 3D or actual. I can't tell with your stuff anymore.

          You've definite gotten really far with this. I love how I find no flaws. Depth of field is on the spot on this one as well as your level of contrast.

            It's 3d, you would know this if you read anything in my post rofl.
            Also I don't have a very good camera, so no picture I could ever take would come out that good.

              I read your post and still thought it was real. I really cannot believe how awesome your stuff is.

                  Seems unrealistic to me just due to the amount of work that would be required to create such glasswork in the real world. You might have had a hard time rendering that thing, but imagine the work it would take to really create it.

                  Looks photo-real though from what I can figure. And is it just me or is there some grain or something to the image to make it look subtly more real?

                    The grain is actually caused by the VRay rendering engine itself when using Depth of Field options, I've just learned to tune the settings a bit so there's not as much grain like there was with the cat picture.

                    VRay needs to clean up this issue in their next release, hopefully it's on their to-do list. And wouldn't glass etching be fairly simple? My dad has a sandblaster and I've watched him do it many times, never tried myself, though it doesn't look hard, especially if you were to stick a vinyl stencil around the cup and then quickly sandblast through the lines.

                      Uh... grain isn't a problem. It's a good thing when used correctly. Like I said, the grain here makes it look subtly more real. Most people probably wouldn't consciously notice it (like the depth of field), but it would still influence their thoughts about how real it looks.

                      Remember: a real photograph is going to have grain. Even digital shots have a similar effect in digital noise. Only rendered graphics are PERFECTLY devoid of these "impurities".

                      And yeah, I'm no expert on glass design, but that sort of thing is uncommon in glassware as far as I know, so I assume it's a lot more difficult than your post implies. Maybe it's just one of those things that's easy for people who know how to do it and have the tools.

                        yeah afro how is that glasswork unrealistic, people around here make this stuff all the time. darksark, you're not gonna have the same outcome as your picture shows with a sandblaster, i'm pretty sure.

                        also professional photographies are nearly completely devoid of graning unless the photographer wants it for stylistical purposes.

                          fine grain != no grain

                          ps I didn't mean the glasswork is unrealistic per se, just that it's not the sort of thing that is common among glass and it would probably ironically look more real without it, even though the whole point was to show how real that unique glassworking technique is rendered here.

                            unintelligible grain by human sight = no grain
