They wouldn't be able to keep it in stock. |

--- Quote from: thinkfat on June 22, 2022, 08:12:21 am ---This is Ektachrome, it's a slide film. You should probably look at an Ektar 100 datasheet to make a fair comparison. Slide film is known to be quite finicky regarding exposure, because the usable range is quite small compared to negative film. Also, the density range is not that important, you can influence that with the developer used, time and temperature anyway, the usable exposure range is what defines dynamic range. --- End quote --- I picked Ektachrome precisely because there's no wiggle room, it always goes through E6 chemistry (unless you're one of the weirdos putting it through C-41 to get funky 'art' rather than accurate reproduction.). Otherwise some bright spark was going to argue about the minutiae of the chemistry used rather than the broad principle. The widest dynamic range you'll get out of any silver emulsion is somewhere between 1000:1 and 10000:1, limited by a Dmax on the close order of 4.0 for continuous tone images (i.e. no fair citing lith film used in strictly black or white processes where Dmax is limited by how much silver you can afford). |

OK, three usable decades of exposure range there. Still less than a digital camera with a reasonably large sensor (i.e. not a phone camera), I believe. And once you create a print on paper, your dynamic range is gone anyway? --- End quote --- Doesn't anyone remember the Zone System? It boils total dynamic range down to f/stops, and that range is Zone 0 for pure black to Zone X (ten) for pure white. So, what, 11 f/stops of dynamic range, or as we engineers like to think, 11 bits. But "usable" dynamic range is somewhat less, so figure Zone II for deepest shadows to Zone IX. Still better than your 8-bit monitor display, right? The point was that you visualized what the image would look like, and then choose your exposure (time and aperture) based on what you wanted to get. Or, as we used to say, expose for the shadows and develop for the highlights (for b&w negatives) so you ensure you capture your shadow detail. For transparencies (slide film), you expose for the highlights to make sure you don't blow them out. |

They are still worthy of being repurposed as external displays. As for the Studio Display, too late here. Been waiting for it for a few years. I had a pre-order in, cancelled that on retail release day and went and picked one up from the local store. The display is actually fractionally better than the last 5k iMac displays are - slightly brighter and higher contrast. Also the speakers are excellent, the camera is excellent (now they fixed the firmware) and it's a thunderbolt hub that actually charges the MBP properly unlike most of the 3rd party junkers. It was worth the price. The pain went away after a couple of weeks :-DD Edit: only criticism is the box is fucking huge. It's currently just about lurking boxed under my desk as I'm in the middle of moving house :( |

--- Quote ---I don't see how 60Hz would cause him to see flicker, unless they were CRTs. LCDs don't flicker, even when run at low refresh rates, unless the backlight driver is faulty, or badly designed. --- End quote --- What if there is fast movement on the screen (as would be expected with games)? There would be discrete steps which might be perceived as flicker. I think peripheral vision is more prone to seeing flicker (certainly is for me with brake lights and roadworks) so the side monitors would be triggering. |
