  6. Re:Colour gamut on Laser TV — the Death of Plasma? · · Score: 1

    Windows has color management support that goes far beyond sRGB. It is capable of doing color space conversions, and its printing subsystem does support this. It's up to the application to spec the source profiles of artwork, and to invoke the ICC support to do the conversion. All that said, Windows color management is crap. That's why all the commercial print products such as Adobe's stuff, disable it.

    I may be wrong but I've been lead to believe the windows ICM converts the photo to sRGB for printing if it's enabled. So, yes, the end result IS printed properly, but it's printed in sRGB space so you lose all the extra gamut that presumably your camera and inkjet are capable of handling.

    I would speculate the ICM behavior is because the manufacturers supply sRGB ICM profiles with their printers.

    Incidentally, photoshop printing doesn't automagically bypass the windows ICM. At least not with Canon inkjet drivers. You get nice double profile conversion resulting in crappy colors unless you un-tick the driver ICM option.

  7. Re:Colour gamut on Laser TV — the Death of Plasma? · · Score: 4, Informative

    Digital cameras can record colours outside sRGB, so if you ensure your workflow never enforces that constraint, you can end up with a file that can be printed using colours your monitor can't see.

    Typically, the input file (usually a raw camera file) is transformed via a device profile (representing the camera's actual spectral response) into a working space (a device-independent space for editing). Whilst editing, the image is viewed using a transform to sRGB (or your display's output profile, if you've calibrated it), but this restriction is for viewing only and doesn't change the file. Then, when you print, the image is converted via a device profile for your printer to print to the extremes of its capabilities - which may exceed sRGB in some colours (e.g. cyan), and be even worse in others (e.g. pure blue).


    Most 6 or 7 component inkjets can go well beyond sRGB gamut.

    Life stops being simple and nice once you take that step, thought. With AdobeRGB for example, you cannot share any of your images with your friends or print them in commercial shops unless the recipient can handle color profiles properly. XP image preview actually can, but none of the browsers do.

    True, you can change the profile but unless you've got full photoshop, it's more conversion steps as the freeware utilities that I'm aware of can only do TIFF and JPG.

    2nd hurdle is actually getting the photos to print. You have to be able to bypass all windows color management (which uses sRGB) and use photoshop (or photoshop elements) to print, which needs to have the profile for your printer AND photo paper for things to work right.

    As an end result, you *may* get images of a lagoon or something that has deeper hues your commercial print shop would print. But how many of images like that "ordinary" people have in the 1st place?

    There are even wider gamuts as AdobeRGB still doesn't surpass what you can see. I think PhotoPro will show all the colors (reference) eye can see and in fact quite a lot it can't, since color vision is not nice and linear.

    Bottom line is, unless you're absolutely sure what you're doing, stick with the sRGB! Going with AdobeRGB or similar will make your photos look WORSE unless the rest of the cain supports it.

  10. Re:If this is true... on The Light Bulb That Can Change the World · · Score: 1

    The main problem with AC/DC Converters is that at higher power consumption, they typically become less efficient. This is partly due to the technologies involved. Switching power supplies are +90% efficient. However, they are solid state and do have a limit to how much power they can supply and still be cost effective. Higher power models require other, more traditional and less efficient converters. The converters can't get much more efficient any time soon. As the more efficient converters drop in price, you'll see them in cheaper applications. In the mean time, efficiency of the device itself is, for now, the best way to go, not in the converters.

    IAASD (I am an SMPS designer) .. AC/DC converter is usually always SMPS (Flyback or forward converter for low powered stuff, half-bridge or full-bridge types for electric tools and the like)) except maybe in high-end audio. Most decent PSUs do have power factor correction too, which doesn't actually make the supply any more efficient but provides much "nicer" load for the network.

    As for the SMPS efficiency, many PC supplies for example are around 70-80% efficient. It takes actually great care to design >90% efficient PSU and requires all kinds of tricks to reach such figures such as storing energy from the filters and gate drivers and feeding it back to the system.

    If you target 75% efficiency, you can get away with much more basic design that uses passive rectifying and turns electromagnetic noise into heat.. At the store you, Joe Consumer, always fork over for the "450W" mystery-PSU which costs 1/3rd of an actually well-designed and built unit (of course price is no guarantee it's been well designed..)

    There are also techniques to extend output power range which is used for example in PC motherboards that have to supply silly current densities to today's processors. For example, 80A at 1.3V for Athlon 64 X2 4800, which is 110W. To reach such output they're probably using 2-phase (40A per phase) to 8-phase (10A per phase) DC/DC converters which have to run at very high efficiency as 20% of 110W = 22W, which is a lot for small semiconductors. So in your typical PC you usually have at least two SMPS circuits in series for the worst power hogs which are CPU and GPU. So for mom + pop 75% efficient PSU and maybe 90% efficient motherboard SMPS you're down to maybe 67,5% efficiency of that ~200W load your CPU and GPU generate while you're playing Half Life..

    So the principal rationale of higher PSU efficiency isn't ecology at all but thermal management. You can cram 92% efficient DC/DC converter into much smaller package with much less aggressive cooling than 75% PSU. Just look at the big-ass 12cm fan at the power supply that sounds like a hairdryer..

    Of course, parent is absolutely correct, Athlon X2 is much nicer about using power than processors from few years ago as it uses similar techniques with mobile processors such as reducing clock speeds and core voltages when you're reading slashdot and not using CPU much, unless you're calculating potential cancer-busting proteins in the background or something.
