• Digital Camera Basics - a Primer This is a good very introductory article

Other Photography Blogs

• FredMiranda.com wide range of reviews, reader contests, plus active and worthwhile forum. Of particular note is the remarkable "Show us your Studio" forum, a single thread which started in October 2004 and is still running at this writing (May 2007).
• The Strobist, a blog about using electronic flash effectively and creatively

Lens Review Sites

• Photodo.com Lens review site (has been arond a long time)
• SLRGear.com (from the Imaging Resource folks, listed above)

Scanning:

• Scan Tips, an excellent reference on everything related to scanning.
• VueScan, a very flexible non-TWAIN scanner driver for Linux, Windows, and Mac OS (9 and X).

Noise Reduction:

• Photo Ninja can reduce digital noise (akin to film grain) from high ISO digital camera images or from film scanning. (Follow-on to original Noise Ninja; now a full image editor.)

EXIF data:

Here's a clever web page I ran across that can show you the EXIF data for photos you see on the web.

• Metapicz EXIF information page

  Or you can see on a map where a photo was taken with pic2map.com. (But click privacy box!)

Buying:

• DealCam is a meta-site that can help you to find good prices. Don't go for the lowest price! (A lot of these places are disreputable!) Ask David for advice on some recommended places.
• ResellerRatings.com is a place where users can rate the vendors who sell equipment. As always, the complainers are going to be the ones who take the time to write. (I have had good experiences with some places with mixed reviews. However, a place with uniformly bad reviews is best avoided, most likely.)
• For a devastating photo essay on a wide selection of the New York photo places that advertise widely, see Brooklyn Store Fronts. (Contrast that with photos of B&H Photo, Adorama, Calumet, and others at Manhattan Store Fronts.)
