The whole pitch for the new On Air Design of ARD we did was originally specified for some sport events that were coming up on the ARD channel soon and which then will be promoted in HD. The quest thus was also included in designing a siginificant key visual which stands for the basic identifications of the HD technology.
For the logo ARD demanded something what reminds on the line art they did in the early 80's something like a line egg:
I put on the first logo tests of Marcos and modified them with some wave and sine deformers to get a more liquid Effect.
In the first place HD is interpreted with sharper and bigger Images. Sharpeness not uncommonly is interpreted with a sharp lense Focus on specific objects, so putting something in focus would demand parts which are in focus and others don't - which means in a shorter sense: Depth of Field.
I considered using post blurred depth of field by a z-buffer image or luminance depth, but then it often results to blur effects which are not always the best, especially when it comes to fine details like the lines we used.
Considering that we are not using much post layers for this logo i thought it might be best rendering the depth of field effect already in the image.
Mental ray since the version 2008 has a nice bokeh lens shader which allows also to use your own bokeh images.
Knowing that if you magnify images through a glass and not having chroma corrected lenses the images often have the red and blue light shifted based on the refraction index. to get the effect already in the rendering without post filters i shifted my red and blue channels of my bokeh image already in photoshop which result you can see here:
using this bokeh gave me a much better result than i would ever get when using standard post blured Depth of field renders. Though it took some time to render, because getting nice depth of field i needed a proper sampling rate at around 32 or more samples to reduce the grain in the picture.
Generating several different shots with different focus animation i composited them on after effects with the design mainly created from Marcos.
