I have found that whilst shooting cityscapes at night (and bracketing), the best transparency for scanning is normally 0.5 to 1 stop lighter than the best slide for projecting.
I think a lot is going to depend on how well your scanner copes with dense transparencies.

I seem to recall the dpreview preview of the 300d saying that the image chip was being made *for* Canon in Taiwan, whereas the 10d chip was made in-house *by* Canon.

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.

Practically all film scanners will be able to scan mounted slides as well as unmounted film strips. There are a few flatbed scanners with transparency adapters that can also scan mounted slides too.

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.

You'll find it helpful to select manual focusing, otherwise some cameras won't fire a shot because they can't focus in those conditions.

Thanks for your responses.

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.
<p>
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>

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>"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...

You might want to check out <a href="http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=00657v">my thread from earlier</a>, which shows some of the problems I've had with my 28-135mm IS lens. The consensus of the replies implies that it's a design fault/poor lens rather than being faulty.

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.

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'.

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.
