Photoshop Tonic
Just been playing with Cinema 4D (and a fair smattering of Photoshop and Illustrator). I set myself a little exercise playing with reflections, transparency and refraction. When I had finished I found this on my screen.  |

Delicious! But it looks like you've drunk both bottles. (Good thing you're no longer in air traffic control.) Can you fill them up again? |

We've got friends round for dinner and they're polishing off the rest of the case! I'll get them re-filled tomorrow. Prosit! |

Re: Photoshop Tonic
Gordon, That looks very real!! Did you create the bottles from scratch? |

Re: Photoshop Tonic
Hi Anna, The bottles were created in a 3D programme (Cinema 4D). I created the outline of a cross section of half a bottle in Illustrator and then converted it to paths and saved it as an .eps file. This was opened up in Cinema and the outline (path) was ‘lathed’ to produce a complete bottle. This was given some transparency and a refractive index and then lit in Cinema. The labels were created in Photoshop and added in Cinema. I used the background image of the iceberg in Cinema to get the refractions. The whole thing was then rendered in Cinema to produce a .psd file with Alpha Channels. The Alpha Channels allowed me to cut out the bottles and the reflections and then place them separately onto the original iceberg shot so that I could work on both the iceberg and the bottle images in Photoshop. The ‘liquid’ in this new post was re-rendered in Cinema but the bubbles and a few bits of shading were added in Photoshop. Hope I haven't lost you there.

Re: Photoshop Tonic
hi Gordon those are very cool bottles..! did you make the iceberg reflection on the water or is it real? 
i`ve been playing with a 3d programme myself (3d max) but still can`t achieve a level of realism like yours i`m afraid  |

Hi David, Thanks for the comments. The iceberg is real as is the reflection. The water surface that day was like glass and gave some really spectacular photographs. I haven't used 3dmax but all 3d programmes take a bit of learning and I'm at the very bottom of the learning curve with Cinema. |

Re: Photoshop Tonic
Wow! I'm going to have to start learning Cinema! This image is fantastic. I have one tiny little isuue (which is after all what this forum is about). I don't like the bubbles! The rest of the inage is so hyper real that they don't look like they belong in the image. I know how sifficult creating realistic bubbles can be, and on my Jekyll poster I failed miserably and took a shot of real bubbles instead. Can you create bubbles in Cinema instead? You certainly don't look like you're at the bottom of the learning curve, however! Chris |

Hi Nick & Chris, Thanks for the comments. Chris. Yes you can make bubbles in Cinema. Create a sphere. Give this some transparency. As it is composed of a gas it will need no refractive index. (Air = Refractive Index of 1) You can then copy and paste this and move the copies around inside the 'liquid'. Making the first bubble is the easy bit but it takes a little time to distribute lots of them depending on how many bubbles you want in your bottle. The advantage of doing it this way is that the bubbles themselves get distorted due to the refraction of the liquid and the bottle so they look more realistic. I chose to put the bubbles in using Photoshop as it was quicker. What I should have done was to create the bubbles then select that Layer, switch to the 'bottle' layer and Cmd-J. This would make copies of the bubbles from the background. Then apply the embossing in Layer Effects and reduce the transparency to taste.  |

Re: Photoshop Tonic
Chris, It has just occurred to me that you can of course put lots of bubbles in by using an 'array' object and just altering the number and amplitude in the array. Create just one sphere of the correct size and then add it to the array. Make two or three arrays with bubbles of different sizes and 'Robert is your Mother's brother'. Glad you asked the question; it set my mind thinking about the problem. |

Re: Photoshop Tonic
What is an array object - is that in PS? |

Re: Photoshop Tonic
Hi Chris, Sorry no. I didn't make that clear. It's in Cinema |

Re: Photoshop Tonic
Gordon, that is a great image. Does Cinema4D use a massive amount of computer space up? And does it take a long time to render? |

Re: Photoshop Tonic
Hi Deborah, The actual programme is quite small and the .c4d file sizes are also quite small. They are mathematical types of file so they can be kept quite small. The finished file size that you create can be very small or extremely large depending on what parameters you choose to render at. For most purposes you would only be creating fairly small file sizes. You can render out to tiff or psd. Render times can be an issue but they depend on how large a file you are creating and how many calculations the programme has to make as regards any transparency or refraction in the scene. As an example the original bottle scene was rendered to 2,500x 2000 pixels giving a 45Mb file. This took just over 15 minutes to render out on a 450Mhz MAC G4. The pain about this is when you render it out and you find that you have forgotten to add (as I did) one of the textures to an object and you have to re-render. |
