  • Created discussions Bye!
    It's bad enough being called wrong when I'm not, the final straw was deleting a thread I stared because someone didn't like it.  I left two years ago because of those things, and I should have ...
  • Created discussions Resolution
    What I've been talking about is resolution.  What Lin insists on talking about and using to claim I'm wrong is digital cameras.  Yes, Lin, you're probably right.  There probably isn't much ...
  • I fail to understand how you can claim interpolation is equivalent to capturing the actual light.  I understand de-mosaicing.  I understand interpolation.  I understand error correction and data ...
  • Nice shots of the foundation and door.  Where's the one that shows what the old grocery store itself looks like?
  • My comments are, and have been, about the absolute, not some specific camera or group of cameras.  Your comments are that within a limited set of cameras, DR makes no difference. Again: If you have ...
  • Dynamic range is at least one-half of a camera's resolution.  Just think if the camera had no dynamic range.  It could only capture one light value.   Q.E.D.  Even if a camera's DR were infinite, ...
  • Why use a wide angle?
  • 1) Apparently you're using the wrong eye. 2)  You're allowed to open that eye when you're not looking through the viewfinder.  I fact, there's no law that says you have to close it WHILE looking ...
  • In my experience, no software can 'upsize' a digital image to a significantly larger size satisfactorily.   There seems to be no technique that yields satisfactory results, either.
  • I'm well aware that resolution varies with film type. Resolution is not simply about 'pixel' size or count, is it? Dynamic range is a huge factor and you have to divide a Bayer sensor's pixel ...
  • What does color vs b&w film have to do with it? I'm curious.  Of course you can make large, beautiful prints with digital, but where' the fine detail?  What exactly is the resolution of digital ...
  • I'll take the liberty of thanking you for this information on behalf of a Sigma forum participants.
  • I'm certainly no technophile, but I found this after a real quick search: http://kenrockwell.com/tech/film-resolution.htm The section titled ' The Digital Resolution of Film ' is especially ...
  • Have yo ever considered . . . film?  It's very high resolution and you can probably find a used compact film camera on eBay for a very reasonable price.
  • It isn't the amount of ram. The Mac's CPU is much more powerful than the ones in IBM-PC derivatives. Also, the video system in the Mac might be faster than the one in your PC, contributing to the ...
  • Thank you both for your clarification. I haven't followed any cameras other than Sigma dSLRs, and even those not recently. It was my understanding that the discussion was about a viewfinder vs. an ...
  • Sorry, but I fail to understand how anyone would want to focus using the LCD---or even how they could.  It doesn't have enough resolution.  On the other hand (and in theory), the resolution of the ...
  • The spoked part is equivalent to a car's 'rim' (don't know what it's called), the outer part is actually called the "tire", and tires wear out and have to be changed.  (That's what's being done ...
  • I've run into that problem.  Windows software used to be notorious for not releasing memory when the program ended, but apparently that's not the problem here.  It seems that SPP is taking more ...
  • Replied in Why not?
    The only thing I did is change the alignment from portrait to landscape.  PhotoShop 'suggested' making sure the printer was set to control color itself, but my printer's software isn't ...
