No problem guys. As Joakim mentioned one more thing in the look chain is the use of tiffen black- and gold diffusion FX (1/2) filters. It did a small but noticable enhancement of the pictures.
Here are some tips about blendingmodes and preserving highlights:
Use the technique contrastmasking(you can find it on several photoshop sites) in conjunction with overlay/hard light blendingmode which adds contrast and saturation. Then there are some more goodies like emulating blackdiffusion and white diffusion with the help of screen blending mode.
Her are som techniques to preserve or make blown highlights better.
An easy one is where I use two layers to re-add hihlights after I've added contrast to a scene. I put an unchanged clip(before contrast) under the clip where I add contrast. Then I remove the blownout bits with a lumakey which reveals the intact highlight from the original(of course this only works on highlights that havent been blown out.
If you have blown highlight I recommend the following technique.
1. Lower the whites in levels filter.
2. Tint the highlight
3.add noise to the highlights(which gives the illusion that the camera has registered "something" which is better than a pure white signal.
Another teqnique is to add a fake background or even some diffuse very lite pattern that gives hint of something. If you've moved the camera you need to track it so the background doesen't drift.
