You should change the Color Space setting on your camera from sRGB to AdobeRGB to capture color differentials at a higher resolution.

Wow, great post. I had no idea CF8 had a way to extract EXIF data. Thanks!!

Pete in CF 8.1 I am getting zero data returned. Did they change something or is there something I have to do before playing with ImageGetEXIFMetaData?

Is there any way to remove EXIF data before saving an image? Thumbnail for ~2.5Kb can weight ~205Kb just because of EXIF, which is useless in this case.

Hi Pete and thanks for this article.

How can I get the Date/Time out of exif? There is no problem e.g. getting the model info like this: <cfoutput> #exif.model# </cfoutput> But where can I get the "name" for all the Date/Time functions?

<cfoutput> #ImageGetExifTag(img, "Date/Time Original")# </cfoutput>

I have noticed one thing, we use the User Comment field in the EXIF data and with CF8 it comes back as an empty string. CF9 appears to have corrected the issue and returns the contents of the User Comment field. Looks like I'll have to upgrade.

Really great article with very interesting information. You might want to follow up to this topic!?! 2011

I understand what you mean, but for the pseroups of the Tiobe index do they actually make those same distinctions when analysing other languages? If built-in image manipulation functions are part of the framework and not part of a discussion about the programming language that they belong to then similarly every C# article that mentions a native package or Windows API should be excluded from the index but I highly doubt they are excluded. But this isn't really my point When someone talks about ORM in ColdFusion 9, interfaces in ColdFusion 8, or CFC-based custom tags in Railo they are talking about "the language". All these things would be excluded from the Tiobe index because they are being pointlessly pedantic about the use of the word "ColdFusion" or "Railo" or otherwise. The fact is we all say "ColdFusion" far more than we say "CFML", even when we mean "the language not the application server". Chances are someone at Tiobe just doesn't like ColdFusion and thought it would be funny to only rank it based on "CFML" and "CFScript", and we all fall for it every time.
