  1. Re:This too will pass on Protecting Unexposed Film from Cosmic Radiation? · · Score: 1

    Electronics die. And there are very few cameras produced today that do not have any electronics in them.

    Almost every 4x5 camera on the market does not have any electronics. As for the longevity of the camera... My Busch Pressman Model D is about 50 years old, and working fine.

    This question was about 4x5 sheet film, not APS or 35mm.

    I used to get teased about using outdated technology by members of our local photo club who shoot crop-factor digitals and project digitally, until I brought in my 6x6 projector and put some images up on the screen.

    And rightly so. You should be hiding & un-hiding or inserting elements using the DOM, never using document.write (which F's up your DOM tree).

  8. Pelican Case or UK Case! on iPods to be Used as Flight Data Recorders · · Score: 2, Informative

    I work at a distributor where we sell both (otterboxes are the low end line of Underwater Kinetics). Pelican and UK cases are better for this application because they're vented. Otter Boxes have a higher crush pressure, but may burst if there's sudden decompression.

    I wouldn't recommend either company's iPod cases for this application either. Go with something like a Pelican 1200 or UK 5010 so that there's LOTS of foam padding. We're not talking about 15 minutes of jogging followed by a drop from 1 meter, we're talking about hundreds of hours of vibration.

    We have customers that buy UK or Pelican cases, then drill through them to mount ruggedized connectors like Cannon or Amphenols, RF connectors (RFI or Amphenol), or Eaton harsh environment switches to use for controls. Both lines stand up well to field abuse.

  9. Re:Use DC in the data center on Renewable Energy for the Data Center? · · Score: 1

    Which makes me wonder why there isn't a 48VDC input ATX power supply on the market. Voltage regulators are cheap compared to the rest of the components in a power supply, and many can use in excess of 48V input.

    You should only be compiling from scratch in your devel environment, and be installing binaries in your testing and production environment. Even if your devel and test environments are just chroot jails on the sysadmin's workstation.

    Erm... "Upload.php" is a logical thing to call a script which accepts an upload... it doesn't necessarily mean they all do the same thing. Ever noticed that there are an awful lot of C functions called "char** parse(char* s)" even though many programs have errors in their parse function?

  23. Re:Too expensive - get a flatbed on Scanners for Large Negatives? · · Score: 1

    Digicams don't have movements.

    35mm gives me adequate amounts of data for most puropses; 6x6 gives me enough to do 24"x24"@300ppi. Only my press camera gives me perspective and focal plane control.

    As for the "mediocre quality" nonsense, please substantiate it.

    It's not DMax; it's clear from my histograms that my 9950f has enough DMax to capture the data from my film. Even my slides of fireworks are not fully opaque.

    It's not sharpness; useable imagte sizes like 100 MegaPixel are enough of a downsample to restore critical sharpness.

    For those who require extreme flatness, you can fluid mount on a flatbed.

  24. Missed an item... on Scanners for Large Negatives? · · Score: 1

    Scan emulsion (dull) side down and mirror image it in software. If you scan emulsion side up (like the manual for my 9950f says to), the images often have nasty newton's rings.

    I haven't had a newton's ring since I started scanning emulsion down.

  25. Ignore the drum scanner comments. on Scanners for Large Negatives? · · Score: 4, Informative
    I use a CanoScan 9950f for 4x5 and 6x6 (inches and cm, respectively; the photography world is funny like that). It does just fine for prints up to 24"x24"@300ppi from 6x6. True, a drum scanner is sharper, but so many times the price, and you can get similar results by over-scanning and downsampling. True, a flatbed doesn't have the same DMax, but your negatives aren't fully opaque anyways.

    Try this (for B&W negs):
    1. Use a CanoScan 9950f or Epson v750*
    2. Get a registered copy of VueScan
    3. Scan at your scanner's max physical resolution for 6x6, and 1/2 max for 4x5
    4. Set white and blackpoints to 0.
    5. Scan at 16 bit depth greyscale, 2 samples, no sharpening, no dust correction
    6. Save as 16 bit Tiff
    7. Load your images in Cinepaint or Photoshop CS or Elements 4 or later
    8. Adjust the "Levels" to set your desired black and white points.
    9. Save this to your archive as a 16 bit tiff.
    now, for each desired print or display size:
    1. Open the image in your editor
    2. Resample down to the desired size (@300ppi for minilabs and many inkjets, 360ppi for Epson inkjets, ignore ppi and dpi for screen display)
    3. Apply unsharp mask (you can sharpen a LOT on large B&W)
    4. If you have a profile for your printer or lab, convert to that. If you're sending to a minilab you don't have a profile for or posting online, convert to sRGB.
    5. If printing on your own printer, save this file as print-ready, 16 bit profiled tiff.
    6. If you're sending to a minilab or posting online, convert to 8bit and save as JPEG (98% qual for minilabs, 75% ish for posting
