  1. Peter, Good question. I put my faith in the quato's as their modified Betac McGreth DT94 Colorimeter is externally certified byUGRA. Their calibration software has presents for HDTV (HDTV (ITU-R BT.1361 / BT.709) or DCI (Gamma 2.6, 6.300K) compliant calibration). Actually I've just spotted a dedicated Broadcast Monitor on their site: IP260 Braodcast Monitor for those interested. To be pedantic you're right Peter I haven't verified any one companies claims about their product myself. But needless to say, no one really does. regards, Wolfgang
  2. Hi, My background is more still imagery, with the workflow target towards four colour print process, so I may be stepping on a few feet here, but... (read my blurb here...) http://www.cinematography.com/forum2004/in...showtopic=33250 The assumption that computer monitors don't have black is based on the knowledge that nearly all monitors are shipped out with too high brightness/background light level (200-350cd/m2) . This encourages burn out of the colourants, and increases sales when your £2000 proofing monitor starts showing colour fringng after a couple of years... (sarcasm off) Anyway a properly (hardware) calibrated and software profiled device will have proper black. (assuming that 0 cd/m2 is black, tolerance 0.1 cd/m2) Modern proofing monitors don't implement a gamma correction but rather use L* for the tonal response. (quato monitors do) The gamut of the monitors can not only be described by their primaries, the ranges look like strange beasts. See my current profile attached. (white is FOGRA isocoated, White my current display) The L* TRC can be adjusted to your liking values between 1.6 and 2.4 are common. The advantage of using a monitor like this is that that the deviation between hardware calibration and ICC profile towards an output target is not done by the graphic card (at a loss of display gamut) but rather in the monitor. The monitor is connected via USB cable to the computer, where the calibration software feeds the monitor the ICC profile. The graphic card remains unaware of this and continues to send a full 255, 255, 255 range of signals. The conversion towards the target profile is then executed by a chip inside the monitor. (in 12 bit/channel) On a system like this I would assume that you can safly carry out any grading you like, as (from experience) you can expect your colour rendering to fall within ΔE0.5 (ΔE1 being the limit where the "Standard Observer" will start to differentiate colours, and ΔE4 being the accepted deviation in print processes) Hope this helps, Wolfgang
  3. Phil, Tnaks for that, I found "Rushes" who are also organising soho short film festival, which is coincidently where my project is heading (next year...) Cheers! Wolfgang
  4. Naim, Let me shed some light on the matter. As Michael has indicated, calibration implies that you know what you are calibrating for. There is a vast number of hardware calibrated, soft-proofing etc monitors around. A lot of the manufactures will blind you with their marketing blurb. You need to do your part of the homework first. Eizo makes affordable hardware calibrated screen, but most of them (although very good) only achieve an sRGB gamut. Eizo 21CG This is fine if your output gamut is mostly covered by the screen. But you sure as hell wouldn't want to use that monitor for soft-proofing a ISO Coated v2 CMYK image. (Just to prove a point). You can check what standards are equivalent (i.e. what gamut your target has) here (pdf) One of the highest gamuts , excellent uniformity, monitors are Quato Wide Gamut Monitors (although I believe they will break your bank) Calibration devices: For the highest affordable standard colorimeters, try to get your hand on the Quato Silverhaze Pro or DTP94 colorimeter. They are improved designs of the Gretag Macbeth colorimeters, and to my knowledge the only UGRA/FOGRA certified "standard" colorimeters. (I know you're not producing print media, but these guys are ultra picky and what's good for them ain't bad for you) Sony seized production of CRT tubes in 2000, affecting the identical Mitsubishis as well. Production of monitors phased out around 2005 when old tube stocks where used up. As of 2008 Samsung is not including CRTs in their product line any more. As it looks, the future (for now) lies with LCDs. Hope this helps a little. regards Wolfgang
  5. Yes I'm after a greater dynamic range. Not fussed about the format really, as long as AE/Fusion accept the format as footage. (hence the post title, "scan to ..." ;) I'm asking around here as I've written to about 9 or 10 places so far, but no luck. regards, Wolfgang
  6. Hello everyone, I'm looking for a company that can scan 8mm and 16mm film to .exr or similar. There are tone of companies that offer all sorts of "home" coversions, but I'm interested in getting back a stack of openEXR files. If there's no-one catering for small film formats in the UK, I'll happily look further afield, suggestions welcome! Thanks a lot... regards, Wolfgang
