  1. <p>An HDR image may or may not go beyond the human eye's ability to capture the range of the scene (most probably do not). But in either case, that's not why they often look unnatural. They look unnatural because they COMPRESS the range of the scene into the range of the reproduction medium, which is far less. You are reacting to the fact that the shadows and highlights are far closer together tonally than they would be in the original scene. Conventional photography does this as well, but to a much lesser extent.</p>
  2. <p>People see what they want to see or expect to see. It's telling that the first sighting of the Windermere monster seems to have been in 2006, yet there have now been eight of them. This lake is in England, no, not some remote Amazonian jungle?<br /> Nobody had seen a flying saucer or a bald alien with large eyes until the 1950's either.</p>
  3. <p><em>"The only reason prices are going up is because market demand will support the higher prices. Production cost and currency rates only set a floor on prices; not a cap."</em><br>

    Factually incorrect. Production costs and exchange rates have a great deal of effect on the profit-maximizing price. Take an econ course some time.</p>

  4. <p>Canon didn't sell $34 billion of cameras in a quarter, nor even in a year. Not even close. That figure is Canon's annual sales for all products.<br>

    I don't know where they got the Nikon figure either. Their total sales were about $7 billion in 2007. Canon does sell more cameras but it's mostly a matter of Canon being a more diversified company.</p>

  5. <p>@Shawn - you don't need quarks (which are unlikely ever to be photographed anyway) to show quantum effects, even to a layman. Double-slit experiments have been done with objects as large as buckyballs (60 carbon atoms). Hydrogen atoms are as good a quantum object as any, really, so your hypothetical experiment has just been done. You won't ever see any weird behavior in a photograph, because a photograph is just the sort of measurement that collapses the particle's wave function. <br>

    I don't understand the fascination on the part of laymen with "photographs" being some sort of definitive proof anyway. They're just one way of representing certain data. Things certainly exist that can't be photographed, and not everything in a photograph exists.</p>

  6. <p>The other "cult" cameras you mentioned have a following for legitimate reasons. The rationale you mentioned might some day make the D700 the answer to a trivia question, but that's about it.</p>
  7. <p>Unless you have some fairly exacting technical requirements, photography can be done pretty cheaply these days. The old film gear is being given away, and if you go digital you don't have to buy film and processing. I would guess that you're probably the victim of marketing. You can do a lot with a Holga and Tri-X if you want to, or any number of inexpensive digitals. If money is keeping you from your hobby, you are doing it wrong.</p>
  8. <p>Oops, my original answer neglected the fact that these were senior portraits! Sorry about that.<br /> The botanical gardens adjacent to Piedmont Park would be my first choice. It does cost something to get in. I used to go there with a macro and telephoto with closeup accessories to do shots of bugs and flowers, but there is really nice landscaping for portraiture. </p>
  9. <p>The guy was a jerk, but the prosecution is ludicrous. The courts should take a very dim view of any assertion that recording police interaction with the public is forbidden in any way. And no, telling someone to turn off their camera is not a "legal order." Telling you where you can stand to use the camera is, but there is no legitimate reason whatsoever to tell you to turn it off. On the contrary, in addition to dashboard-mounted cameras being standard, some departments are starting to put tiny cameras on officers' uniforms.</p>

    <p>I guess I need to send the ACLU another grand or so. It's been a while.</p>

  10. <p>You can expense capital equipment in a single year, no problem. The limit is over 100 grand. I've expensed basically every computer and business-related piece of software I've ever bought. On the other hand, if for some reason you're not anticipating a profit this year anyway, you'll want to depreciate it.</p>
