Glurrk is right: COLLATERAL was shot on HD format and had an high experienced DP working on it. The HD format is still experimental (don't care about what Rodriguez says), and in fact they had any kind of problems with it.
28 DAYS was shot with a couple of CANON XL1S mini-DV cameras that are Normal Definition Cameras (EDIT: I should've said Standard Definition...whatever...) and don't need a balls-like-bulls cinematographer to get it right (I have a XL2 progessive scan camera myself and is not that hard to make it working good) - but, of course, since they're semi-professional cameras, their results are not the same as what you can get with HD when it works good.
28 DAY LATER transferred on 35mm (the version you could see at the movies) was looking like a 16mm blow-up, but less fascinating (no TEXAS CHAINSAW MASSACRE-ish). This is because you can have the highest resolution ever, but if you're recording on a small tape like the Mini-DV, you'll never see the result on screen. Is not strange that COLLATERAL, THE RUSSIAN ARK and all the movies shot on progessive scan in HD had the camera linked to a big hard disk (the size of a backpack) to not lose any pixel of resolution.
HD is still an expensive format: one day, as everything connected to digital technology, it will be cheap and what Rodriguez says (everybody doing their own movies that look like real ones) will be true. Now, only Studios can say it is cheap.
But if VACATION will be distribuited only in Home-Video, it will look very well.
I don't understand your sarcasm, SIC.
