    I reckon the first skirmish in the loudness war was Phil Spector's Wall

    played it in the disco.

    I _think_ he achieved his effect by ensuring that most of the audio
    spectrum was used, rather than any compression: compression (for studio
    use) was in its infancy then, apart for on some US AM radio stations.

    And yes, one can _prefer_ vinyl; that's not saying it's _better_. (On
    distortion and dynamic range alone, is certainly isn't - to degrees in
    both cases that surely exceed any more subtle aspects.) And yes, there
    are going to be aspects of its distortion that are more pleasing to the
    ear - much like "valve sound", where (a) class A was used more so
    crossover distortion was less common and (b) they didn't "hard clip" so
    much so if overdriven anyway, it was less obvious.

    Valve amps had more in reserve than early solid state amps, and could
    exceed their RMS continuous power by a significant margin for long
    enough to let a piano's peaks come through clean. Transistor power
    supplies were too low voltage to do the same trick.

    Peak-to-mean power rating - oversimplifying, but basically the size of
    the smoothing capacitor in the power supply section! - was yet another
    factor. Voltage as such wasn't the governing factor. As Liz has
    explained, valve circuits tended to use less feedback, meaning when
    driven out of their (more or less) linear range, the distortion was less extreme: they were less linear in the safe region (but with harmonics
    that tended to be not very objectionable), but if overdriven, didn't
    "hard clip" as obviously.

    True, but I think he achieved it in a way that all sides - engineers and general listeners - certainly found acceptable, and many found novel. As compared to compression, which engineers certainly weren't impressed
    with, and many general listeners weren't either when it was pointed out
    to them.

    Yes. Even I have the equipment here to do it for 35mm slides, using a
    digital camera and a holder, and when quality matters, I use RAW format,
    then edit to suit before compression. JPEG is a lossy format, so is not
    the best choice when editing, as you get generational losses each time
    you change something in a saved image. I can even restore slides where
    the fading is different in each layer, going as far as the odd occasion
    when one or more colour layers has, in effect, reverted to a negative.

    For a very reasonable price, you can buy a slide scanner which will scan
    the slides or film roll onto an SD card or into your computer, and most
    image editing programs have a range of automatic filters which can do a
    rough balance on a batch of images. The current batch of scanners can do
    any where from 150dpi to 7,000 dpi, with prices to match.

    There are companies advertising the service both for stills and movies.

    There are lots of such devices, from about 20 quid (probably less s/h)
    up to ones that have things like infrared to detect scratches etcetera.
    But, as you say, would take hours for all but a small number.

    I take it they're mounted? I've seen scanners with a hopper you can feed
    them into, then operate pump-action like a shotgun: if you've not _too_
    many, that might be worth an investigate. (I don't know how well they
    work with the different types of mount - Kodak thin card, Agfa thick
    plastic, Boots thin plastic ... maybe OK if not mixed?) How many slides
    are you talking about - and what are they in? If projector magazines,
    maybe something could be done with the projector, though I've not heard
    of anyone doing that. Obviously those wouldn't automate exposure/colour.

    For personal recommendations, maybe you have a local photographic club/society/whatever? Look in your local library at the notice-board.
    (Include historical.) I imagine most of those _will_ have done it
    themselves, but there might be some who've used an outside source and
    can recommend (or the opposite!).

    One cautionary tale. I have found that the IR dust/scratch correction of
    slides does not work with Kodachrome, because that film absorbs IR by
    different amounts according to density of image. Ektachrome and the Agfa
    slide films absorb IR uniformly, irrespective of image density, so they
    can distinguish between image and dust. For Kodachrome, you must turn
    off IR and retouch dust manually; with it turned on, the results are not
    pretty :-(

    Our music master at school used to sell bulk (monochrome) negative, penny-a-frame IIRR. I used to refill 126 cartridges with it!
    ("Instamatic"), and then reversal process: black-and-white slides.

    The master at my school who ran the photographic club bought a bulk load
    of B&W negative film and dispensed it to us in reusable plastic 35 mm
    canisters which we could develop and print. Sadly there was a bit of
    grit in the felt light-trap of his bulk loader, so everyone's films
    ended up with a tramline all the way down :-(

    I've only once experimented with B&W slide film. I forget the precise
    details, but I remember that it was *very* slow - either 16 or 32 ASA -
    and I think it may have been made by Agfa.

    I can't remember how the reversal was achieved - whether it was
    performed chemically or whether it involved the film being exposed to
    uniform light after first development and bleaching. Maybe I overexposed
    it to the reversal light or overdeveloped it after that (second
    development) but all the slides were a bit dark and muddy.

    I'm trying to remember which way round it was for Kodachrome and E6 (Ektachrome) - one was chemical reversal and one used a light exposure
    after first-dev. I think Kodachrome used light and E6 used chemical
    (non-light) reversal, but I may have that the wrong way round.



    When it comes to scanning negs and slides, I've found that slides are a
    *lot* easier and require considerably less faffing around and tweaking
    of settings in the scanner's control app. Slides usually "just work",
    and the only adjustment necessary is exposure, whereas negs can look
    muddy, over-saturated and "larger-than-life" - a look which you often
    used to get in 1940s/50s books that included "colour plate"
    illustrations. Also I got horrendous blooming around dark objects (eg
    chimneys of a building) against a light background (eg sky) and very
    coarse grain. That was the case both for a flat-bed scanner and a
    dedicated Minolta film scanner. After a lot of faffing (with different parameters for every single frame) I got some good results which showed
    details in shadow and highlight which were bleached out or lost in
    blackness of a print from the same neg.

    I was staggered at the amount of highlight detail that I could recover
    from overexposed slides. I took some Ektachrome slides of night-time
    scenes - eg floodlit buildings such as the Cabot Tower in Bristol when I
    was at university there - complete with a deep blue filter to correct
    tungsten lighting to daylight film. I had to make wild guesses at
    exposures, and some guesses were better that others! Some slides looked
    washed out when projected, but when I scanned them many years later, I
    was able to get pretty good results with highlight detail that I though
    had been lost forever.

    Scary that nowadays a DSLR can give instant feedback of correct
    exposure, even if you have to alter the metered exposure by n stops
    until the picture looks right, and you can colour-correct immediately by
    the time-honoured process of taking a photo of a white piece of paper
    which is illuminated by the same light. My experience is that digital
    cameras tend to produce better results with discontinuous spectrum
    lights such as fluorescent or LED - none of the sickly green cast that fluorescents gave with Kodachrome ;-)

    I've only once experimented with B&W slide film. I forget the precise >details, but I remember that it was *very* slow - either 16 or 32 ASA -
    and I think it may have been made by Agfa.

    The slides I produced didn't use dedicated B&W slide film - I didn't
    even know such a thing existed. The process used ordinary B/W negative
    film, with extra chemicals from Johnsons and instructions, including the re-exposure part way through the process.

    When it comes to scanning negs and slides, I've found that slides are a
    *lot* easier and require considerably less faffing around and tweaking
    of settings in the scanner's control app. Slides usually "just work",
    and the only adjustment necessary is exposure, whereas negs can look
    muddy, over-saturated and "larger-than-life" - a look which you often
    used to get in 1940s/50s books that included "colour plate"
    illustrations. Also I got horrendous blooming around dark objects (eg >chimneys of a building) against a light background (eg sky) and very
    coarse grain. That was the case both for a flat-bed scanner and a
    dedicated Minolta film scanner. After a lot of faffing (with different >parameters for every single frame) I got some good results which showed >details in shadow and highlight which were bleached out or lost in

    I've always thought slides - though I admit, and negatives - probably
    contain much better depth than prints; the only disadvantage likely
    being that it's much easier to obtain good resolution by scanning a
    print, assuming you've got a good print that is.

    paper which is illuminated by the same light. My experience is that
    digital cameras tend to produce better results with discontinuous
    spectrum lights such as fluorescent or LED - none of the sickly green
    cast that fluorescents gave with Kodachrome ;-)

    I suspect the light sources have improved somewhat too.
