Getting EXIF Metadata with ColdFusion 8

One example that I've been meaning to post is how to get Image Metadata using the Exchangeable Image File Format or EXIF a using ColdFusion 8. It's actually quite simple, to get a list of all the EXIF tags simply use the ImageGetExifMetaData function.

Here's a quick example:

<cfimage action="read" source="#ExpandPath("lobster.jpg")#" name="img">
<cfset exif = ImageGetEXIFMetaData(img)>
<cfdump var="#exif#">

Here's a screen shot of a CFDUMP of the EXIF Image Metadata.

As you can see some of the useful keys are Model which gives you the digital camera model (Canon EOS DIGITAL REBEL XTi in this example), Make gives you the digital camera brand (Canon), Exposure Time gives you the exposure time (1/60 sec).
