  1. I had one of these a while back. It can produce good results, but the big problem with mine was that it couldn't cope very well with dark areas in images - there was significant banding present. Actually, now I think about it, it produced banding in uniform lighter areas too, like clear blue skies.

     

    I only kept it for a year during which time I sent it back to Nikon twice - they reported that it was within its design parameters.

     

    Hope yours is better.

  2. Beau describes it perfectly. I'll just add that this phenomenon is referred to as 'outgassing' or 'out-gassing', which is described in many places on the web, e.g. <a href="http://www.inkjetart.com/news/gassing.html">this inkjetart article</a>.

    <p>The phenomenon is not limited to either Epson or Ultrachrome inks.

    <p>If you place a piece of plain paper over the print for a day or two as suggested, it's surprising how wavy that paper gets, in a pattern corresponding to the image on the print.

  3. I used a 28-85 for about ten years, then switched to the 24-85. That extra 4mm at the wide end made a big difference for me. I tend to shoot at the wider end and it gives more flexibility. There is a bit of distortion at the wide end, though. Here's one at 24mm.
  4. Thanks for your responses.

    <p>

    I've read up on diffraction and as far as I can tell, that's just going to make the images softer rather than giving these colour fringes. Looking back through some images, I found another shot of a very bright white line next to a dark railtrack. The white line had a bright purple fringe and that was shot at F5.6. So I don't think it's diffraction, but I will definitely get an ND filter to smooth water.

    Puppy Face says '...if you're going to be that critical...'. I don't really accept this argument. If this is chromatic aberration caused by a design limitation, then this is worse than I have ever seen, even from lenses costing a third as much. I find it difficult to accept that a company like Canon would be prepared to even put their name on it or release such a poor product to market.

    <p>

    This leads me to think that the lens is actually faulty in some way, unless...

    <p>

    The colour fringes do look quite similar to some examples of Moire artifacts I saw on the <a href="http://www.lashier.com/home.cfm?dir_cat=20523&gal_col=1">Lashier photography site</a>

  5. Forgive me if you've already found these links, but you can access the technical support page for the scanner here <br><a href="http://www.nikonusa.com/usa_tech_center/dtc_options.jsp?cat=1&grp=2&productNr=9290">http://www.nikonusa.com/usa_tech_center/dtc_options.jsp?cat=1&grp=2&productNr=9290</a>. <p>Specifically, you'll need to get an ASPI driver so that Windows 2K can talk SCSI to the scanner - it's discussed thru the FAQ 'General SCSI Setup Information'.

    <p>Extract from page:

    <p>"Nikon does not support the use of "USB to SCSI" or "Firewire to SCSI" converters. SCSI Scanners can only be used with computers which have either a built-in SCSI port or an approved SCSI PCI card.

    <p>"When connecting a Nikon SCSI device to a Windows based computer a pieces of software called �ASPI� needs to be installed. This is basically driver software that �teaches� the operating system how to interact with SCSI devices. The easiest way to obtain this ASPI software is to download it from the Adaptec web site.

    <p>"Follow the link below (or search for �ASPI� on the downloads section at �www.adaptec.com�).

    <p><a href="http://www.adaptec.com/worldwide/support/drivers_by_product.html?sess=no&cat=%2fProduct%2fASPI-4.70&prodkey=Windows+ASPI+Package">http://www.adaptec.com/worldwide/support/drivers_by_product.html?sess=no&cat=%2fProduct%2fASPI-4.70&prodkey=Windows+ASPI+Package</a>

    <p>"Users may also wish to download the �ASPICHK� utility. When run, this software will display a list of which versions of the ASPI software are installed and is useful when troubleshooting.

    <p>"No ASPI software is needed for Macintosh computers."

    <p>Hope this helps...

  6. This is my first forum thread - please be gentle with me.

    <p>I have some strange colour fringes that are appearing adjacent to

    highlight areas in my images. I've attached a sample image, taken

    with my EOS 10D, down-sized to 600 pixels wide. I've highlighted a

    number of areas as white boxes, and these sections are shown

    separately, magnified by a factor of two.

    <p>Most of the colour fringes are near the edges, red on the left,

    purple on the right, but there's even a slight fringe towards the

    middle.

    <p>If it was a film camera, I'd suspect chromatic aberration from a

    really poor lens, but the body is digital and the C.A. is at a level

    far worse than I've seen with any other lens. Is there another

    explanation? Perhaps digital artifacts from the anti-aliasing filter?

    Is something faulty?

    <p>Here's the technical info:<br>

    <p>Thanks for your advice. I hope I haven't committed a gross faux

    pas with all these images, but they are all quite small.

  7. If playing a DVD on a set-top (i.e. non-computer) DVD player is important to you, you could check out <a href="http://www.dvdplusrw.org/resources/compatibilitylist_dvdvideo.html">this compatibility list</a> for DVD+.

    <p>I think one of the selling points of DVD+ is that it <i>tends</i> to be compatible with more players than DVD-. Although I dare say that most new ones will support both formats.

    <p>If you're UK-based, you might want to get hold of the latest edition of PC Pro magazine which has a review of many different DVD writers and explains the format differences. This is also available on-line. Go to <a href="http://www.pcpro.co.uk">www.pcpro.co.uk</a>. Then click on 'view all labs' (under 'Lab Tests'), then click on 'DVD Re-writers'.
